// aim : To determine
// the heat transferred to the gas and its final pressure
// Given values
m = 2;// masss of the gas, [kg]
V1 = .7;// volume,[m^3]
T1 = 273+15;// original temperature,[K]
T2 = 273+135;// final temperature,[K]
cv = .72;// specific heat capacity at constant volume,[kJ/kg K]
R = .29;// gas law constant,[kJ/kg K]
// solution
Q = m*cv*(T2-T1);// Heat transferred at constant volume,[kJ]
mprintf('\n The heat transferred to the gas is = %f kJ\n',Q);
// Now,using P1*V1=m*R*T1
P1 = m*R*T1/V1;// [kN/m^2]
// since volume of the system is constant, so P1/T1=P2/T2
// hence
P2 = P1*T2/T1;// final pressure,[kN/m^2]
mprintf('\n The final pressure of the gas is = %f kN/m^2 \n',P2);
// End
