3 cards from this section. Quick, good the night before a test.
What is latent heat?
Think about phase changes.
What is the latent heat of fusion for ice?
Consider the melting process.
What is the formula for calculating latent heat?
Think about what we discussed regarding phase changes.
True or False: The latent heat of vaporization for water is 2260 kJ/kg.
Recall the specific values for water's latent heat.
If 1 kg of ice at 0°C is warmed to 100°C and then evaporated into steam, calculate the total energy required.
Remember to break the problem into phases: melting, heating, and vaporizing.
To pour 300 grams of liquid water at 100°C into ice, how much energy is released when the water cools to 0°C before becoming ice?
Calculate the cooling energy and then the energy for freezing.
