Practice Questions

Question 1

In a calorimetry experiment, which equation is used to calculate the heat transfer for a substance?

Question 2

A metal sample of mass 30 g is heated to 120°C and then placed in 100 g of water at 25°C. The final temperature of the system is 28°C. What is the heat gained by the water? (Specific heat capacity of water is $4.18 \, \text{J/g°C}$)

Question 3

If the heat capacity of a calorimeter is $10.0 \, \text{J/°C}$, and the temperature of the calorimeter increases by 5°C during a reaction, what is the total heat absorbed by the calorimeter?

Question 4

A 40 g sample of an unknown substance absorbs $1,200 \, \text{J}$ of heat, causing its temperature to rise from 20°C to 50°C. What is the specific heat capacity of the substance?

Question 5

In a calorimetry experiment, 150 g of water is mixed with a hot metal sample. The water temperature increases from 22°C to 30°C. If the specific heat capacity of water is $4.18 \, \text{J/g°C}$, what is the heat gained by the water?
