A heater is used to heat water at an energy rate P = 4,124 J/s. How long will it take to heat mwater = 20 kg of water from Tinitial = 20°C to Tfinal = 80°C?

Question

anonymous · Answer

Is this a chemistry question? If not, any formulae?

anonymous · Answer

delta Q= c*m*delta T

anonymous · Answer

find delta Q (the total heat energy used to heat from T=20 to T=80)

anonymous · Answer

divide that total energy by the power to get the time

anonymous · Answer

this is a physics question the specific heat for water is 4186j there was no response in the physics section so i thought i'd try my luck here
