What amount of heat is required to completely melt a 29.95-gram sample of h2o(s) at 0°c?
(1) 334 j (3) 1.00 × 103 j
(2) 2260 j (4) 1.00 × 104 j

The latent heat of fusion for water is 334 Joules per gram. Since there are 29.95 grams, we multiply 334 by 29.95 = 10003.3 Joules, which is about choice (4) 1.00 * 10^4

The answer is b i think

Answer) by studying proton collisions hope this : )
