How many joules of energy are required to melt 423g of water at 0°C?

hope this helps mark me BRAINLEST plz ;)

Explanation:42. Practice Problem  How many joules of energy are required to vaporize 423g of water at 100oC and 1atmosphere of pressure. q = mHv m = 423 g Hv = 2260 J/gq = (423g) (2260J/g) = 955,980 J = 956 43. Table T – Heat Formulas
