I need the formula for the question, if the hot tub heater provides 5900 kj/min, how long in hours will it take to heat the water in the hot tub from 69f to 112f? Help please

Answer 1

Convert 69F to C; convert 112F to C. Use C or Tfinal and Tinitial below.
How much water do you have in the hot tub? You don't have that in the problem.
q needed in Joules = grams H2O x specific heat H2O x (Tfinal-Tinitial)

Then 5,900,000 J/min x ?min = q needed in J from above.
