198. Inside two containers with equal volumes, there are $n$ moles of oxygen gas and the same number of moles of helium gas respectively. During an isobaric process, we give equal amounts of heat to both gases. If we denote the ratio of the increase in temperature of helium to the increase in temperature of oxygen by $k$, and the ratio of the change in internal energy of helium to the change in internal energy of oxygen by $m$, which option is correct? \[
(1)\quad m=1,\ k>1 \qquad (2)\quad m=1,\ k=1 \qquad (3)\quad m<1,\ k<1 \qquad (4)\quad m>1,\ k>1
