For an ideal gas :A. The change in internal energy in a constant pressure process form temperatures `T_(1)` and `T_(2)` is equal to `nC_(v) (T_(2) - T_(1))` where `C_(v)` is the molar heat capacity at constant volume and n is the number of moles of the gasB. The change in internal energy of the work done by the gas are equal in magnitude in an adiabatic processC. The internal energy does not change in isothernal processD. no heat si adoed or removed in an adiabatic process |

Answer» Correct Answer - A::B::C::D (1) `Delta U = nC_(v) (T_(2) - T_(1))` in all processes. (2) `Delta U = - Delta W` `|Delta U| = |Delta W|` ( `Delta Q = 0` for adiabatic process) (3) `Delta U = 0` for isothermal process (4) `Delta Q = 0` for adiabatic process |
