Thermal Propert...

The temperature below which a gas should be cooled, before it can be liquified by pressure only is termed as 

The velocity of heat radiation in vacuum is 

Four rods of identical cross-sectional area and made from the same the metal form the sides of square. The temperature of two diagonally opposite points and $$T$$ and $$2T$$ respective in the steady-state. Assuming that only heat conduction takes place, what will be the temperature difference between the other two points 

A thermos flask is polished well

Three rods of the same dimension have thermal conductivities 3K,2K3K,2K. The temperature of their junction is 

At constant volume the specific heat of a gas is $$ \dfrac{3R}{2} $$ , then the value of $$\gamma $$ will be 

At a given volume and temperature , the pressure of a gas

At NTP the mass of one litre of air is $$1.293\,gm$$. The value of specific gas constant will be 

For matter to exist simultaneously in gas and liquid phases 

Beryllium has roughly one-half the specific heat of water $$(H_2O)$$. Rank the quantities of energy input required to produce the following changes from the largest to the smallest. In your ranking, note any cases of equality.
