If R is universal gas constant the amount of heat needed to raise the temperature of 2 moles of an ideal monoatomic gas from 273 ~K to 373 ~K when no work is done is

Step-by-step solution

For an ideal gas, the internal energy in only a function of the gas temperature and is a measure of the mean translational kinetic energy of the atoms. Q = U + Q =0 Q = U = n 2 R T When n = degree of freedom for monoatomic gas i.e =3= 3 2 2 R (373-273)=300 R
