Question

In the formula used to solve problems related to the first law of thermodynamics, what does Q represent? A.internal energy

Answer 1

Answer:

B.heat

Explanation:

As we know by First law of thermodynamics

$Q = \Delta U + W$

as we know that

Q = heat or thermal energy supplied to the system

$\Delta U$ = change in internal energy of the system

W = work done by the system

So first law of thermodynamics is basically energy conservation law in which energy supplied to the system is converted into its internal energy and work done by the system.

Answer 2

B, heat, is the correct answer. Heat is represented by a capital q in thermodynamic equations.
