Air is filled ina motor car tube at $$27^oC$$ temperature and $$2\ atm$$ pressure. If the tube suddenly bursts then the final temperature will be [given $$(1/2)^{2/7} = 0.82$$]

$$1\ g$$ mole of an ideal gas at $$STP$$ is subjected to a reversible adiabatic expansion to double its volume. Find the change in internal energy ($$\gamma = 1.4$$ )

Variation of molar specific heat of a metal with temperature is best depicted by 

A mass of ideal gas at pressure $$P$$ is expanded isothermally to four times the original volume and then slowly compressed adiabatically to its original volume. Assuming $$\gamma$$ to be $$1.5$$, the new pressure of gas is

The pressure inside a tyre is $$4$$ times that of atmosphere. If the tyre burst suddenly at temperature $$300 K$$, what will be the new temperature?

At $$27^{o}C$$ a gas is compressed suddenly such that its pressure becomes ($$\dfrac{1}{8}$$)th of original pressure. Final temperature will be ($$\gamma$$ = 5/3)

A diatomic gas initially at $$18^{o}C$$ is compressed adiabatically to one eightth of its original volume. The temperature after compression will be

A perfect gas goes from state A to another state B by absorbing $$8 \times 10^5J$$ of heat and doing $$6.5 \times 10^5J$$ of external work. It is now transferred between the same two states in another process in which it absorbs $$10^5J$$ of heat. In the second process

$$80\ g$$ of water at $$30^o C$$ is poured on large block of ice at $$0^{\circ}$$C. The mass of ice that melts is

The volume of a gas is reduced adiabatically to $$\dfrac{1}{4}$$ of its volume at $$27^{o}C$$. If $$\gamma= 1.4$$ the new temperature is :
