Question

A copper coin with a mass of 6.30 grams changes temperature in the sunshine from 20.0°C to 32.0°C. How much energy is transferred? The specific heat capacity of copper is 0.377 joules/gram degree Celsius. Express your answer to three significant figures.

Answer 1

The energy transferred is 28.5 j.

Answer 2

The energy transferred is 28.5 j

calculation

energy is calculate MCΔT formula where,

M(mass)= 6.30 grams

C(specific heat capacity)= 0.377 j/g

ΔT(change in temperature)= 32.0c- 20 c= 12 c

Energy is therefore= 6.30 g x 0.377 j/g /c x 12 c =28.5 j
