What quantity of heat is required to change 40.0 g of ice at melting point to liquid water? The heat of fusion of ice is 335 J/g.

Question

Quizplus · Accepted Answer

The formula to calculate the heat required to change a substance from solid to liquid is:

q = m * ΔHfus

where q is the heat required, m is the mass of the substance and ΔHfus is the heat of fusion.

Substituting the given values, we get:

q = 40.0 g * 335 J/g
q = 13,400 J

Therefore, the heat required to change 40.0 g of ice at melting point to liquid water is 13,400 J. The correct answer is (A).
