You are a legend

[@ytuber3168]

But change in internal energy= ΔE=Q+W. However, everywhere you have taken ΔE=Q-W. Why? Is it correct?
Thanks

[@sammylatterell1410]

The sign convention for work is opposite than that of heat transfer. Work done TO your system is negative, work done BY your system is positive. So ΔE=Q-W.
