Question

An ideal gas expands from an initial volume v into vacuum under isothermal conditions. For this process. u0,w=0 and q0u0,w=0 and q0 u0,w0 and q0u0,w0 and q0 u0,w0 and q=0u0,w0 and q=0 u=0,w=0 and q=0

Answer 1

at Isotherm U=0

it is expands do q= -ve

from formula of first law U = q+W

so W = -q
