# NEET Physics Thermodynamics Questions Solved

NEET - 2010

If  represent the increase in internal energy and work done by the system respectively in a thermodynamical process,which of the following is true?

(a) $∆U=-∆W,$ in a adiabatic process

(b) $∆U=∆W,$ in a isothermal process

(c) $∆U=∆W,$ in adiabatic process

(d) $∆U=-∆W,$in a isothermal process

From first law of thermodynamics

$∆Q=∆U+∆W$

For adiabatic process $∆Q=0$
