please homework help
A bowl of 582 g of water is placed in a microwave oven that puts out 729 watts (J/s). How long would it take in seconds to increase the temperature of the water from 12.0oC to 46.6oC?
q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
729 J/s x #seconds = q
Solve for # seconds.
