3 cards from this section. Quick, good the night before a test.
What is latent heat?
Think about phase changes in materials.
What is the latent heat of fusion of ice?
Consider how much heat is needed to melt ice at 0°C.
What is the heat required to melt 1 kg of ice at 0°C?
Think about what heat you need for the phase change from solid to liquid.
Does the temperature of a substance change during a phase change?
Consider the example of melting ice.
If you start with 1 kg of ice at -10°C, how much heat is required to turn it into steam at 100°C? Provide a detailed walkthrough of the calculation.
Break it down into stages: heating ice, melting, heating water, and vaporizing! Then sum those amounts.
A scientist is conducting an experiment with 300 grams of water and needs to figure out how much energy is required to freeze it at 0°C. What is the computation process?
Think about using the heat of fusion for freezing instead of melting!
