Question

First law of thermodynamics tells us:

• A. the direction in which a given process can take place
• B. the nature of the process taking place
• C. that heat supplied is used to carry out the process
• D. to what extent the process takes place

Answer 1

The correct option is C

that heat supplied is used to carry out the process

First law of thermodynamics tells that whenever heat is supplied to a system, a part of it increases the internal energy and remaining heat is used in doing external work. Hence, it tells us that heat supplied is used to carry out the process.
