The pressure in a gas is 1000 Pa, and its volume changes from 1 cubic meter to 2 cubic meters. The work done on the gas

Question

is positive

is negative

is zero

requires more information

Those are the choices, please help! thank you.

Answer 1

This is a case of expansion of gas under constant pressure

W =P ( v2-V1)

The work is done by the gas ( +ve work )

Hence work done on gas the is negative
