An electric heating coil is immersed in 4.2 kg of water at 22°C. The coil, which has a resistance of 260 Ω, warms the water to 33°C in 3.5 mins. What is the potential difference at which the coil operates?(adsbygoogle = window.adsbygoogle || []).push({});

I was looking through the chapter, and did not see any equations that I can use that involve temperatures, but does this problem involve the equation q(t) = CE[1-e^(-t/T)]?
