Specific Heat Calculations Worksheet

Question 1

A 50.0 g sample has a specific heat capacity of 0.900 J/(g·°C). How much heat does it gain as its temperature rises by 10.0 °C?

1. 4.50 J
2. 45.0 J
3. 450 J
4. 4,500 J

Question 2

A 25.0 g sample with c = 0.400 J/(g·°C) cools from 60.0 °C to 40.0 °C. Calculate q for the sample, including its sign.

Question 3

Two samples have equal mass and gain the same heat. Sample A has the higher specific heat capacity. What is true of the temperature changes?

1. A’s temperature rises less than B’s.
2. A’s temperature rises more than B’s.
3. A’s temperature falls as B’s rises.
4. A and B have equal temperature rises.

Question 4

During melting at constant temperature, a solid absorbs energy. Explain why using q = mcΔT alone would miss that energy transfer.

Question 6

What is the final temperature of block B?

1. 20.0 °C
2. 30.0 °C
3. 35.0 °C
4. 40.0 °C

Question 7
