QAIPMT-2010-Ph-2052: NEET 2010 Physics - Class 11 AIPMT-2010-Ph-2052 Solution: If \( U\) and \( W\) represent the increase in internal energy…

If ΔU\Delta U and ΔW\Delta W represent the increase in internal energy and work done by the system respectively in a thermodynamical process, which of the following is true?

Multiple Choice Options

  • A ΔU=−ΔW\Delta U=-\Delta W, in an adiabatic process
  • B ΔU=ΔW\Delta U=\Delta W, in an isothermal process
  • C ΔU=ΔW\Delta U=\Delta W, in an adiabatic process
  • D ΔU=−ΔW\Delta U=-\Delta W, in an isothermal process

Step-by-Step Verified Solution

By first law of thermodynamics, _ Q = _ U + _ W In adiabatic process, _ Q = 0 _ _ U = _ _ W In isothermal process, _ U = 0 _ _ Q = _ W
