On the Kelvin scale 0 degrees Celsius is,

One calorie is equal to

• the amount of energy required to change the temperature of one gram of water by one degree Celsius.

• 4.186 Joules

• 0.001 kilocalories

• all of the above

The amount of heat entering the Earth's atmosphere is

• greater than the amount leaving the Earth's atmosphere

• less than the amount of heat leaving the Earth's Atmosphere

• The same as the amount of heat leaving the Earth's Atmosphere

• Nonsense, the Earth is an isolated system

An ideal calorimeter is one where

• all calories are converted into heat

• calories are measured carefully

• no heat leaks out of the container

• temperature can be measured

When 100 grams of water at 20 degrees Celsius is mixed with 100 grams of water at 50 degrees Celsius, the final temperature is

In the calorimetry simulation, did the 20 degree sample of water change more in temperature than the 50 degree sample of water?

• yes

• no, the 20 degree sample changed less in temperature than the 50 degree sample

• No, the change in temperature for both samples was the same.
