Problem

0.75\,\text{mol}

sample of argon gas is held in a rigid, thermally insulated container at an initial temperature of

290\,\text{K}

. A heater supplies

1.1\times10^{3}\,\text{J}

of energy to the gas. Assuming argon behaves as an ideal monatomic gas and no work is done, what is the final temperature

T_2

of the gas? (Take

R = 8.31\,\text{J/mol\,K}

.) a)

380\,\text{K}
