Water has a specific heat of 4.18 J/g- °C. What is the quantity of energy (in kJ) required to increase the temperature of a 50.0 g sample of water from 25 °C to 99 °C?

1 answer

q = mass H2O x specific heat H2O x (Tfinal-Tinitial)
Substitute and solve for q. The answer will be in joules. Convert to kJ.
