Answer #1

Heat Capacity : The amount of heat required to raise the temperature of the substance by 10C

Specific Heat Capacity:The amount of heat require to raise the temperature of 1 gram of a substance by 10C

Average specific heat capacity = mQT, where m is mass ,Q is the heat capacity of whatever sample taken like water and T is change in temperature

Let m= x gram of substance(Assume sample say water )

Q= specific heat of water 4.184 J/ g 0C (assume as units not given)

T= change in temperature (final-initial) = 10C

Average heat capacity= x gram 4.184 J/ g 0C 10C = 4.184x J
