1. The problem statement, all variables and given/known data An electrical resistence has a power of 1 kW. It is put inside a container that has 10 liters water. The water is in temperature 20C with pressure 1 atm. Find the time to warm the water to the temperature 120C 2. Relevant equations A=P*t 3. The attempt at a solution I thought to use the equation p1/T1=p2/T2 and t=P/A. How can i find A?
