Question: If the latent heat of fusion of ice is 334 J/g, how much heat is required to melt 50 g of ice? (2019)

Options:

Correct Answer: 1670 J

Solution:

Heat required = mass × latent heat = 50 g × 334 J/g = 16700 J.

If the latent heat of fusion of ice is 334 J/g, how much heat is required to melt 50 g of ice? (2019)

If the latent heat of fusion of ice is 334 J/g, how much heat is required to melt 50 g of ice? (2019)

Step 1: Identify the mass of ice you want to melt. In this case, it is 50 grams.
Step 2: Identify the latent heat of fusion of ice, which is given as 334 Joules per gram (J/g).
Step 3: Use the formula to calculate the heat required: Heat required = mass × latent heat.
Step 4: Substitute the values into the formula: Heat required = 50 g × 334 J/g.
Step 5: Perform the multiplication: 50 × 334 = 16700 J.
Step 6: Conclude that the heat required to melt 50 g of ice is 16700 Joules.

Latent Heat of Fusion – The amount of heat required to change a substance from solid to liquid at its melting point without changing its temperature.
Heat Calculation – Using the formula Q = m × L, where Q is the heat required, m is the mass, and L is the latent heat.
