Six moles of an ideal gas performs a cycle shown in figure. If the temperature are Ta = 600 k, Tb = 800 k, Tc = 2200 k and Td = 1200 k, the work done per cycle is Six moles of an ideal gas performs a cycle shown in figure. If the temperature are [...]

An ideal gas is initially at temperature T and volume V. Its volume is increased by ΔV due to an increase in temperature ΔT, pressure remaining constant. The quantity 5 = ΔV / VΔT varies with temperature as An ideal gas is initially at temperature T and volume V. Its volume is increased by ΔV [...]

Assertion: The internal energy of an ideal gas does not change during an isothermal process. Reason: The decrease in volume of a gas is compensated by a corresponding increase in pressure, when its temp. is held constant. Assertion: The internal energy of an ideal gas does not change during an isothermal process. Reason: The decrease [...]
