The amount of heat needed to melt 423 g of water at 0°C is 141282 J
The heat required to melt water can be obtained by using the following formula:
Q = mL
Q is the heat required.
L is the latent heat of fusion (334 J/g)
m is the mass.
With the above formula, we can obtain the heat required to melt the water as illustrated below:
Mass of water (m) = 423 g
Latent heat of fusion (L) = 334 J/g
Heat (Q) required =?
Q = mL
Q = 423 × 334
Q = 141282 J
Therefore, the amount of heat needed to melt 423 g of water at 0°C is 141282 J
