16g of `O_(2)` at `28^(@)C` is compressed to half of its initial volume under reversible isothermal conditions. If this gas behaves ideally, the workdone and change in internal energy in this process are
A. `Delta U = 0` and w = -1251.2 ln 2 J
B. `Delta U = 0` and w = +1251.2 ln 2J
C. `w = Delta U = +1251.2 ln 2J`
D. `Delta U = -1251.2 ln 2J` and `w = +1251.2 ln 2J`
A. `Delta U = 0` and w = -1251.2 ln 2 J
B. `Delta U = 0` and w = +1251.2 ln 2J
C. `w = Delta U = +1251.2 ln 2J`
D. `Delta U = -1251.2 ln 2J` and `w = +1251.2 ln 2J`
Correct Answer – B
`Delta U = Q+W`
