Question

An ideal gas system undergoes an isovolumetric process in which 20 J of energy is added as
heat to the gas. What is the change in the system's internal energy?

-20 J

0Ј

5J

20 J

Answer 1

Answer:

20 J

Explanation:

as volume remains constant hence work done is zero

internal energy = heat given to system -work done by system

                           = 20 J -0

                            = 20 J
