Compare the energy needed to raise the temperature of 1kg of water from 20°C to 100°C and the energy needed to boil 1kg of water at 100°C?

Question

I turned 1kg to 1000g water is 4.18J/g°C and subtracted 20°C then i get confused as what to do next to

Answer 1

q1 = energy needed to raise T from 20 C to 100 C.
q1 = 1000g x 4.184 J/g*C x (100-20) = ?

q2 = heat needed to boil 1,000 g H2O at 100 C.
q2 = 1000 x heat vaporization in J/g = ?
