Demonstate that the inerval energy `U` of the air in a room is independent of temperature provided the outside pressure `p` is constant. Calculate `U`, if `p` is equal the normal atmosphere pressure and the room's volume is equal to `V = 40 m^3`.

The internal energy of the air, in a room of volume V, at temperature T and with outside pressure p increasing linearly with time, varies as

The internal energy of air in a room of volume 40 m^3 atstandard atmospheric pressure is

Estimate the total number of air molecules in a room capacity 25m^(3) at a temperature of 27^(@)C and 1 atm pressure.

Find the internal energy of air in a room of volume 40m^(3) at 1 standard atmospheric pressure.

The total number of air molecules in a room of capacity 20 m^(3) at a temperature of 27^(@)C and 1 atm pressure is

Volume of a room is 15 m times 12 m times 8m . The room was at 22^@C in the morning.What is the percentage of initial volume of air of the room that is expelled when the room temperature reaches 30^@C at noon? The pressure remains constant during the increase in temperature ,atmospheric pressure remains constant.

Find the internal energy of air in a room of volume 40 m^(3) at 1 standard atmospheric pressure. gamma_("diatomic") = 1.41
