Answer:

U

Step-by-step explanation:

The first law of thermodynamics states that:

$\Delta U = Q-W$

where

U is the internal energy of the gas, which represents the sum of the chemical and thermal energy stored in the atoms and molecules of the gas

$\Delta U$ represents the variation of internal energy

Q is the heat absorbed by the system

W is the work done by the system

So, the sum of the chemical and thermal energy stored in atoms and molecules is represented by U, the internal energy.
