An electrical heater is used to supply 200.0 J of energy to a 30.0 g sample of water, originally at 285.0 K. Determine the final temperature in degrees Kelvin. (the specific heat capacity for water is 75.291 Jmol-1K-1)

Answer 1

q = mass x specific heat x (Tfinal-Tinitial)
Remember to change mass H2O to mols H2O if you use sp.h. in J/mol
