what is the relation between Cp and Cv? please answer soon
During an Adiabatic Process, the pressure of a gas is directly proportional to the cube of its absolute temperature. Find the ratio of Cp/Cv. Please help, its important. Thanks!
Why G is called a universal constant.?
What is heat engine? Explain the principle of working of heat engine ? Define its efficiency ?
The temperatures of equal masses of three different liquids A , B and C are 12 degree celcius , 19degree celcius and 28degree celcius respectively. The temperature when A and B are mixed , is 16degree celcius andwhen B and C are mixed , is 23 degree celcius . What will be the temperature when A and C are mixed ?

Define Quasi Static Process in simple words ?
i have the the definition but not able to fully understand it....plz help.
Calculate the increase in internal energy of 1 kg of water at 100 degrees C when it is converted into steam at the same temperature and at 1atm.Te density of water and steam are 1000kg/m^2 and 0.6 kg m^ -3 respectively. The Latent heat of vapourisation of water is 2.25 X 10^6 J kg^ -1.
why is it named zeroth law?????? wat is its significance?????

(Here degree of freedom is 5/3 )
how is the slope of an adiabatic curve steeper than an isothermal curve ?
a certain gas at atmospheric pressure is compressed adiabatically so that its volume becomes half of its original volume .Calculate the resultinfg pressure in N/m square . Take gamma = 1.4, for the gas and kindly explain the solution .
one gram of water at 373K is converted into steam at the same temperature. the volume of 1 cubic cm of water bcums 1671cubic cm on boiling. calculate change in internal energy if latent heat of vaporisation is 540 cal/g.
Two carnot engine A and B are operated in series.The first one A receives hat at 800K and rejects to a reservoir at TK. The second engine B receives the heat rejected by the first engine and in turn rejects to a heat reservoir at 300K.Calculate the value of T ,when outputs of the two engines are equal.
