Question

Which symbol in the first law of thermodynamics represents the sum of the chemical and thermal energy stored in atoms and molecules?
a. Q
b.W
c.V
d.U

Answer 1

Answer:

U

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.
