How do you solve this question?

How much heat (in joules) must be added to change 20.0 g of H2O(s) at –10.0°C to steam at 110.0°C? The specific heat of H2O(s) is 2.09 J/g °C, of H2O(l) is 4.184 J/g °C, and of H2O(g) is 1.84 J/g °C. The heat of fusion of water is 334.7 J/g and the heat of vaporization is 2259.4 J/g

2. Calculate the amount of energy (in kilojoules) needed to heat 346 g of liquid water from 0°C to 182°C. Assume that the specific heat of water is 4.184 J/gᵒC over the entire liquid range and that the specific heat of steam is 1.99 J/gᵒC. (AHvap = 40.79 kJ/mol for water)

1. Calculate the amount of heat that must be absorbed by 10.0 gram of ice at -20C to convert it to liquid water at 60.0C. Given: Specific heat (ice) = 2.1 J/g.C Specific heat (water) = 4.18 J/g-C Hfus = 6.0 kJ/mol or 334 J/g
