Water and Air Temperature Experiment
SAFETY NOTE
Safety Note: Hot Water
Handle hot water with care. If spilled, it could burn your skin.
Water and Air Temperature Experiment
Conduct an experiment to gather evidence about how water temperature affects air temperature. Follow the instructions below.
Insert one thermometer through the slot of each lid and measure the initial air temperature of Cup 1 and Cup 2. Record your data in the table.
Pour hot water into Cup 1 and cold water into Cup 2. The cups should be about half full.
Safety Note: Hot Water
Handle hot water with care. If spilled, it could burn your skin.
Replace the lids and thermometers, making sure the thermometers do NOT touch the water in either cup.
Wait 2 minutes and measure the final temperature of the air in Cup 1 and Cup 2. Record this data in the table.
Initial Air Temperature

### Water and Air Temperature Experiment
#### Data Table
| | Initial Air Temperature (ºC) | Final Air Temperature (ºC) |
|----------------|-------------------------------|-----------------------------|
| Cup 1 (hot water) | | |
| Cup 2 (cold water) | | |
### Explanation of Temperature Changes
The air temperature in each cup changed due to the transfer of thermal energy between the water and the air. Here's a detailed breakdown of what likely happened:
1. **Cup 1 (Hot Water)**:
- When hot water is poured into Cup 1, it has a higher temperature compared to the surrounding air.
- The thermal energy from the hot water transfers to the air above the water. As the air molecules absorb this energy, they gain kinetic energy, causing an increase in air temperature.
- This results in a higher final air temperature compared to its initial measurement.
2. **Cup 2 (Cold Water)**:
- In contrast, when cold water is poured into Cup 2, it has a lower temperature than the surrounding air.
- The cooler water absorbs thermal energy from the air above it. The air molecules lose some energy in this process, leading to a decrease in their kinetic energy and a reduction in air temperature.
- Consequently, the final air temperature in Cup 2 is lower than its initial measurement.
### Summary of Energy Transfer
- In Cup 1, heat energy transfers from the hot water to the air, increasing the air temperature.
- In Cup 2, heat energy transfers from the air to the cold water, decreasing the air temperature.
This experiment demonstrates how temperature differences between substances can lead to energy transfers, influencing the thermal environment around them.
### Conclusion
Through the experiment, we observe the effects of water temperature on the surrounding air temperature. The changes in air temperature are a direct result of the flow of thermal energy from the water to the air or vice versa, depending on the relative temperatures of the two mediums.
