An ideal gas experiences a change of internal energy of 284 J/kg when its temperature is increased by 12oC (at a constant volume). What is its specific heat

23.5 J/Kg °C

Explanation:

The amount of heat required to raise the temperature of substance of mass 1 kg by 1 degree Celcius.

c = Q / m ΔT

Here, Q / m = 282 J/kg, ΔT = 12

So, the specific heat = 282 / 12 = 23.5 J/Kg °C
