The molor heat capacity of oxygen gas is given by the expression C_(v)=a+bT+cT^(2) where a, b and c are constants. What will be change in internal energy of 8 g of oxygen if it is heated from 200 K to 300 K at constant volume? Assume oxygen as an ideal gas. Given a = 1.2 JK^(-1)mol^(-1), b = 12.8 xx 10^(-2) JK^(-2) mol^(-1), c = 3.3 xx 10^(-7) JK^(-3)mol^(-1) . {:((1),"1000 J",(2),"950.15 J"),((3),"830.5 J",(4),"315.5 J"):}
