Question

One hundred joules of heat is added to a system that performs 60 joules of work. the internal energy change of the system is

Answer 1

U= Q-W
here U is internal energy
change in internal energy is
=100-60
=40j

Answer 2

Answer:

The correct answer to this question is $40j$

Explanation:

Given -  One hundred joules of heat are added to a system that performs 60 joules of work.

To Find - Write the internal energy change of the system.

Internal energy is a property or state function in thermodynamics that defines the energy of a substance in the absence of capillary effects and external electric, magnetic, and other fields.

Using the internal energy,

U= Q - W

Where U is internal energy, change in internal energy is

=$100 - 60$

= $40j$
