Question

5 g of copper was heated from 20°C to 80°C. How much heat energy was used to heat copper?

(specific heat capacity of Copper is 0.092 cal )

Answer 1

Given temperature change=60°C


We know H=mc∆T

H= (5/1000)*0.092×4.2×60 [Multiply by 4.2 to convert it into joules]....
You get the Heat energy...
