1. The problem statement, all variables and given/known data A)You have a tank containing 750 mL of water and a heater outputting a max of 400 W. If you start with the water at 25 degrees, how long till it reaches boiling point? B) How much heat must be input to melt 1 gram of ice? What is the volume of meltwater does this produce? 2. Relevant equations Conductivity for heat? Q/t = (k x A x delta temp)/ d Thats all I can think of 3. The attempt at a solution I have tried with the coductivity of heat formula but i dont there is enough information given. I am so lost, I dont know where to start. Help please!
