2.
Which statement is incorrect
3.
Pressure-temperature relationship for an ideal gas undergoing adiabatic change is
4.
For one complete cycle of a thermodynamic process on a gas as shown in the - diagram. Which of following is correct
5.
5 mole of an ideal gas with initially at STP are compressed adiabatically so that its temperature becomes . The increase in the internal energy of gas in kJ is
6.
A Carnot engine whose source is at 400 K take 200 cal of heat and rejects 150 cal to the sink. What is the temperature of the sink?
7.
Three designs are proposed for an engine operating between 500 K and 300 K. For 1 kcal of heat input, design claims to produce 3000 J of work, design claims to produce 2000 J of work and design claims to produce 1680 J of work. The design which is possible
8.
If , then increase in internal energy when temperature of 2 moles of this gas is increased from to
9.
A given mass of a gas is compressed isothermally until its pressure is doubled. It is then allowed to expand adiabatically until its original volume is restrored and is pressure is then found to be 0.75 of its initial pressure. The ratio of the specific heats of the gas is approximately
10.
When heat is given to a gas in an isothermal change, the result will be
