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

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

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

Define standard atmospheric pressure.

The standard atmosphere pressure is

(a) Show that internal energy of an ideal gas is expressed as U=(PV)/((gamma-1)) when P= pressure, V= volume and gamma=(C_P)/(C_V) . (b) Hence find the internal energy of air in a room of volum 50m^3 at atmospheric pressure. (1Atm=10^5(N)/(m^2))

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 one gram of helium at 100 K and one atmospheric pressure is
