One way that longer thermometers could help in this situation is by allowing for more accurate temperature readings throughout the container. If the current thermometers are not long enough to reach the colder water at the bottom of the container, it may result in inaccurate temperature readings. Using longer thermometers can help ensure that the temperature being measured is representative of the entire container, including the colder water at the bottom.
Alternatively, using a different container could also help in ensuring that all of the cold water sits in the hot water. For example, a container with a narrower base or a taller height could help to prevent the cold water from staying separate from the hot water. By using a container with a design that promotes better mixing of the two temperatures, it can help to ensure a more accurate and consistent reading of the overall temperature of the mixture.
Overall, both of these solutions can help to improve the accuracy of temperature measurements in the container and ensure that all of the cold water is properly mixed with the hot water.
please elaborate more on this:
This could happen by having longer thermometers or by having a different container so all of the cold water sits in the hot.

how could this impact the results ?
Improving the accuracy of temperature measurements and ensuring proper mixing of cold and hot water can have several impacts on the results of an experiment or process:
1. Accuracy of data: By using longer thermometers or a different container to ensure accurate temperature readings, the data collected will be more reliable and precise. This can help in making more informed decisions based on the results of the experiment.
2. Consistency of results: Ensuring that all of the cold water sits in the hot water can lead to more consistent and uniform mixing of the two temperatures. This can reduce variability in the results and help in achieving more reproducible outcomes in subsequent trials.
3. Efficiency of processes: Properly mixing the cold and hot water can help in achieving the desired temperature more quickly and efficiently. This can be important in various applications where precise temperature control is necessary, such as in scientific experiments, industrial processes, or cooking.
4. Avoiding bias: Inaccurate temperature measurements or improper mixing of the cold and hot water can introduce bias into the results, potentially leading to erroneous conclusions. By addressing these issues, the results obtained will be more objective and reliable.
Overall, taking steps to improve temperature measurements and ensure proper mixing of different temperatures can lead to more accurate, consistent, and reliable results in various applications.

Law of conservation of Energy
This report will investigate (insert your research question here) e.g. Does shading improve the passive cooling of a house
Response:
Energy is the ability to do work or cause a change. It can exist in many forms, including kinetic energy (energy of motion), potential energy (stored energy), thermal energy (heat), chemical energy (stored in chemical bonds), and electromagnetic energy (light, radio waves, etc.). Energy is constantly transferred and transformed from one form to another in various processes. The transfer of energy occurs when energy moves from one object to another, while transformation involves energy changing from one form to another. The Law of Conservation of Energy states that energy cannot be created or destroyed but only transferred or transformed. This means that the total amount of energy in a closed system remains constant, even though it may change forms. This law is fundamental in understanding the behaviour of energy in various systems and processes. This report will investigate how does changing the container the different water temperatures go in, affect the change of water temperature when the total amount of water is kept the same.
Method
Original Experiment
1. Use one of the thermometers to measure the temperature of the air (room temperature)
2. Put the beaker in the ice-cream container as shown on the next page. Add 200mL of hot water to the beaker- being careful not to burn yourself.
3. Pour 1500mL of cold water into the ice-cream container.
4. Place the thermometer in the beaker and the other in the ice-cream container. Start the stopwatch and measure the temperature inside and outside the beaker.
5. Measure the inside and outside temperatures every minute. Using the thermometers to stir the water gently. (Don’t take the thermometers out of the water.)
6. Plot both sets of results on a graph of temperature (vertical axis) versus time (horizontal axis). Draw a smooth curve for each set of points. (The curve doesn't have to go through each point- as long as it shows the general trend of the results.)
Modified Experiment:
1. Use one of the thermometers to measure the temperature of the air (room temperature)
2. Put the beaker in the ice-cream container as shown on the next page. Add 200mL of cold water to the beaker.
3. Pour 1500mL of hot water into the ice-cream container- being careful not to burn yourself.
4. Place the thermometer in the beaker and the other in the ice-cream container and put a lid/cover over the containers to make it a closed system. Start the stopwatch and measure the temperature inside and outside the beaker.
5. Measure the inside (cold water) and outside (hot water) temperatures every minute. Using the thermometers to stir the water gently. And then close the lid back up. (Don’t take the thermometers out of the water.)
6. Plot both sets of results on a graph of temperature (vertical axis) versus time (horizontal axis). Draw a smooth curve for each set of points. (The curve doesn't have to go through each point- as long as it shows the general trend of the results.)

Discussion
- Interpretation
• Identify trends in your data and link it back to your theory
The original experiment showed that the water temperature in the hot water rapidly decreased and the cold water only got a little bit hotter. This was because there was more cold water then the hot water, this meant that the cold water would cool down the hot water easier as there was more. In the modified test the cold water quickly increased in temperature, and the hot water only decreased in temperature much slower. This is because there was more hot water then the cold water meaning that the hot water would make the cold water hotter as there was more of an amount of the hot water.
- Analysis/ sources of error
In our experiments, there wasn’t any major human errors that occurred when we did our test. However, there is still a possibility that one of us could have read the thermometers wrong or measured the wrong amount of water that should have been poured into the containers.

The concept of energy involves the ability to do work or cause a change and can exist in various forms such as kinetic, potential, thermal, chemical, and electromagnetic energy. Energy is constantly transferred and transformed from one form to another, following the Law of Conservation of Energy, which states that energy cannot be created or destroyed but only changed in form. This principle is fundamental in understanding energy behavior in different systems and processes. The investigation conducted explores the effect of changing the container on the temperature of water when the total amount of water remains constant.
The experiment involved comparing the temperature changes in water with varying ratios of hot and cold water in two different container scenarios. While the initial test showed rapid cooling of hot water and minimal heating of cold water due to unequal amounts of each, modifying the experiment by reversing the water temperatures led to different results, demonstrating the impact of container design on energy transfer and temperature changes. Suggestions for improvement included using longer thermometers or different containers to enhance accuracy and consistency in temperature measurements. Further investigations may explore optimal room temperatures for such experiments and delve deeper into energy transfer dynamics.
