Effects of Water Temperature on Air

Mr. Reagan demonstrates an experiment with two setups, X and Y, each with a cup and thermometer. Initially, both setups have the same air temperature. Hot water is added to setup X and cold water to setup Y. After a few minutes, the air temperature above setup X increases, while the temperature above setup Y decreases, illustrating the effect of water temperature on surrounding air.

What is the purpose of the thermometers in the experiment setup?

• To measure the temperature of the cups

• To measure the room temperature

• To measure the temperature of the air above the water

• To measure the temperature of the water

What was the initial air temperature above both setups X and Y?

• 44 degrees Celsius

• 21 degrees Celsius

• 22 degrees Celsius

• 19 degrees Celsius

What was added to setup X during the experiment?

• Cold water

• Hot water

• Ice

• 44 degrees Celsius

• 22 degrees Celsius

• 19 degrees Celsius

After a few minutes, what was the air temperature above setup Y?

• 22 degrees Celsius

• 19 degrees Celsius

• 44 degrees Celsius

• 21 degrees Celsius

What was the observed effect on the air temperature above the hot water?

• It increased

• It remained the same

• It decreased

• It fluctuated

What was the observed effect on the air temperature above the cold water?

• It decreased

• It remained the same

• It fluctuated

• It increased

What conclusion can be drawn about the effect of hot water on air temperature?

• Hot water causes air temperature to fluctuate

• Hot water decreases air temperature

• Hot water has no effect on air temperature

• Hot water increases air temperature

What conclusion can be drawn about the effect of cold water on air temperature?

• Cold water causes air temperature to fluctuate

• Cold water increases air temperature

• Cold water has no effect on air temperature

• Cold water decreases air temperature
