1. Use a thermometer to measure the room temperature.
2. Place a beaker in an ice-cream container and add 200mL of hot water to the beaker.
3. Add 1500mL of cold water to the ice-cream container.
4. Place a thermometer in the beaker and another in the ice-cream container. Start a stopwatch and measure the temperatures inside and outside the beaker.
5. Stir the water gently with the thermometers and continue to measure the temperatures inside and outside the beaker every minute. Do not remove the thermometers from the water.
6. Plot both sets of temperature results on a graph of temperature (vertical axis) versus time (horizontal axis). Draw a smooth curve for each set of points to show the general trend of the results.
clealry explain this:
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.)
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.)

WRITE A PSEUDOCODE THAT RECEIVES AGES OF STUDENTS (VALIDATED BETWEEN 0 AND 100), AGES SHOULD BE RECEIVED UNTIL AGE 0 IS ENTERED, WHEN ENTERING AGE 0 IT SHOULD RESULT IN THE NUMBER OF AGES ENTERED, THE NUMBER OF OLDER THE NUMBER OF MINORS AND THE AVERAGE OF THE AGES ENTERED.pseint.
```plaintext
1. Initialize variables: count = 0, sum_ages = 0, num_older = 0, num_minors = 0
2. Repeat the following steps until age entered is 0:
a. Read age from user
b. If age is not between 0 and 100, prompt user to enter a valid age
c. If age is not 0, increment count by 1
d. Add age to sum_ages
e. If age is greater than or equal to 18, increment num_older by 1, else increment num_minors by 1
3. Calculate the average of ages entered: average = sum_ages / count
4. Display the number of ages entered, number of older students, number of minors, and average age
