Final answer:
The specific latent heat of fusion of ice at 3.3 x 10^5 J/kg implies the amount of energy needed to melt 1 kg of ice at 0°C without any increase in temperature.
Step-by-step explanation:
The statement "the specific latent heat of fusion of ice is 3.3 x 105j/kg" means that 3.3 x 105 joules of energy are required to melt 1 kilogram of ice without changing its temperature. This is a measure of the amount of heat needed to change the state of a substance from solid to liquid at constant temperature. The specific latent heat of fusion is an important physical property and is specific to each substance. For water, the latent heat of fusion is often given as 334 kJ/kg, which translates to 334,000 joules per kilogram. Using this figure:
Q = mLf, where m is the mass and Lf is the latent heat of fusion.
For the melting of 1.00 kg of ice at 0°C, we have:
Q = (1.00 kg)(334 kJ/kg) = 3.34 × 105 J.
Therefore, the correct interpretation is that
1) The specific latent heat of fusion of ice is 3.3 x 105 J/kg, and it represents the heat required to melt ice at its melting point without increasing its temperature.
