Circle the correct thermal process$($es$)$ for each of the statements

below about $$U$,$ Q$,$ and Wby$.$ You may need to select more than one

thermal process for each statement. The dotted lines represent isotherms. The circle is

the initial state of the gas.

During which thermal process$($es$)$ will the internal energy of the gas increase?

$12345$ none

During which thermal process$($es$)$ will the internal energy of the gas decrease?

$12345$ none decrease?

During which thermal process$($es$)$ will the gas do positive work?

$12345$ none

During which thermal process$($es$)$ will the gas do negative work?

$12345$ none

During which thermal process$($es$)$ was thermal energy definitely added to the

gas?

$12345$ none
