AIPMT 2005 | Heat and Thermodynamics Question 75 | Physics

An ideal gas heat engine operates in Carnot cycle between 227^oC and 127^oC. It absorbs 6 $$ \times $$ 10⁴ cal of heat at higher temperature. Amount of heat converted to work is

4.8 $$ \times $$ 10⁴ cal

6 $$ \times $$ 10⁴ cal

2.4 $$ \times $$ 10⁴ cal

1.2 $$ \times $$ 10⁴ cal.

One mole of an ideal gas at an initial temperature of T K does 6R joule of work adiabatically. If the ratio of specific heats of this gas at constant pressure and at constant volume is 5/3, the final temperature of gas will be

(T + 2.4) K

(T $$-$$ 2.4) K

(T + 4) K

(T $$-$$ 4) K

The equation of state for 5 g of oxygen at a pressure P and temperature T, when occupying a volume V, will be
(where R is the gas constant)

PV = (5/32)RT

PV = 5RT

PV = (5/2)RT

PV = (5/16) RT
