Perfectly rigid containers each hold n moles of ideal gas, one being hydrogen H2and other being neon Ne.
If it takes 100 J of heat to increase the temperature of the hydrogen by 3.50° C,, by how many degrees will the same amount of heat raise the temperature of the neon?
The main concept used to solve the problem is energy transfer.
Initially, use the expression of energy transfer to calculate the amount of heat required to increase the temperature of the hydrogen. Later, use the expression of energy transfer to calculate the amount of heat required to increase the temperature of the Neon. Finally, equate the both expression to calculate the temperature.
The energy transfer expression is,
Here, Q is the heat, n is the number of moles, c is the specific heat, and T is the temperature.
The energy transfer expression for hydrogen is,

The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then C=1ndQdT. This is the definition of molar heat capacity--the amount of heat Q added per infinitesimal...
