Question

The specific heat capacity of copper is .092 calories per gram per degree c. How much heat is required to raise the temp of a 10 g piece of copper from 0 c to 100 c? how does this compare with the heat needed to raise the temp of the same mass of water through the same temp difference?

Answer 1

Favorite Answer

Q = mc delta t

= (10 g) (0.092 cal/g C) (100 C - 0 C)

= 92 cal

This is smaller with the heat needed to raise the temperature of the same mass of waetr through the same temerature. The specific heat capacity of water is 1 cal/g C

Q = mc delta t

= (10 g)(1 cal/g c)(100 C - 0 C)

= 1000 cal

Answer 2

Heat required = m x s x t

m=mass, s=specific heat of the substance

t=temperature difference

For Copper ,

10 x .092 x 100 = 92 cal

For water,

10 x 1 x 100 = 1000 cal

Copper / Water = 92 / 1000
