How much heat is required, in calories, to raise the temperature of 57.8 g of silver from

17.0°C to 43.5°C, if the specific heat of silver = 0.057 cal/g"C?

87.3 calories of heat is required.

Explanation:

Heat = mcΔT

m = mass, c = specific heat of silver, T = temperature

H = 57.8 g * 0.057 cal/g°C * (43.5 - 17 °C)

H = 57.8 * 0.057 * 26.5

H = 87.3069 cal.

The heat required to raise the temperature of 57.8 g of silver from 17 °C to 43.5 °C is 87.3 calories.
