Air is heated in a glass bottle. the heat energy added to the air is 2.0 × 104 joules. what is the change in internal energy of the gas? identify the thermodynamic process.

The change in internal energy of the gas is .

In fact, the 1st law of thermodynamics states that the change in internal energy of a system is equal to the amount of heat given to the system (Q) plus the work done on the system (W):

In this example, no work is done on the bottle so W=0, while the heat given to the system is , so the change in internal energy of the gas is

B) raising the temperature and reducing the volume of the gas.|-/
