Phase Change Practice - Show your work! Be careful with your units!
1. How many joules of energy does it take to convert 10g of ice at 0 degrees Celsius to water at 0 degrees Celsius?
2. How many joules of energy does it take to convert 14g of liquid at 100 degrees Celsius to steam at 100 degrees Celsius?
3. I have 34 grams of ice cubes at the bottom of my cup at 0 degrees C, and I am thirsty! How much heat will it take to turn them into liquid water at 0 degrees C.
4. How many Joules of energy does 1.0 gram of water lose when it freezes?
5. During which phase change does water absorb the, most heat?
6. How many joules of heat would be used to change 20 grams of water from a liquid to a gas?
7. How many joules of heat would be used to change 20 grams of ice to a liquid?
8. Does it take more energy to melt 20 grams of ice or to evaporate 20 grams of water?
Base your answer to the following question on the diagram below and on your knowledge of Earth science. The diagram represents a weather balloon as it rises from Earth's surface to 1000 meters (m). The air temperature and wet-bulb temperature values in degrees Celsius (°C) and the air pressure values in millibars (mb) are given for three altitudes.
- A cloud is forming at 1000 meters. Identify the phase change that is occurring at 1000 meters to produce the cloud Condensation and deposition.
- For which phase change does water absorb the most energy?
- During which phase change of water is the most energy released into the environment?
Base your answer to the following question on cross section below, which shows the general pattern of water movement in the water cycle. Letter X represents a water-cycle process.
- Describe the process of condensation.
- Which phase change requires water to gain 2260 Joules per gram?
