In the formula used to solve problems related to the first law of thermodynamics, what does q represent? a. internal energy b. heat c. work d. external energy

B.heat

Explanation:

As we know by First law of thermodynamics

as we know that

Q = heat or thermal energy supplied to the system

= 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.

energy can be converted from one form to another, but it cannot be created or destroyed in ordinary chemical or physical means. do not understand what you are asking but hope this
