Question

A copper block has a mass of 0.2 kg and a specific heat capacity of 290 J/(kg·°C). What is its thermal capacity?

Options

• 145 J/°C

• 1450 J/°C

• 58 J/°C

• 580 J/°C

Answer 1

58 J/°C

Explanation:

Thermal capacity = m × s = 0.2 × 290 = 58 J/°C. This means 58 J of heat will raise the temperature of this block by 1°C.
