Suppose a quantity of gas, held in a fixed volume V and initially at the ambient temperature
Question:
Suppose a quantity of gas, held in a fixed volume V and initially at the ambient temperature T0, is heated by a resistor to temperature T. Let Q be the heat delivered by the resistor and let CV be the (assumed constant) heat capacity of the gas at constant volume. How much energy is destroyed in this process? Show that when T − T0 ≪ T0 essentially all of the initial energy is destroyed.
