Val warms up some soup on the stove. assuming no phase change has occurred, what effect does warming have on the soup?

its particles have less kinetic energy.
its particles have more kinetic energy.
its specific heat increases.
its specific heat decreases.
(i think its the 3rd one but can someone check my answer)

Atoaster oven has a resistive heating element. the average rate at which it dissipates energy as thermal energy is 1.00 \(\rm kw\). in the united states, emf amplitude in household circuits is \(\mathcal e_{\max}\) = 170 \({\rm \; v}\) and the \(\rm ac\) oscillation rate is 60 \(\rm hz\). part a what is the root-mean-square current through the heating element?
