Question
Phase changes of water (conversions between ice, liquid water, and water vapor) occur constantly in Earth's atmosphere. Heat is either released into the atmosphere (heating the air) or extracted from the atmosphere (cooling the air) during phase changes. Use your knowledge of phase changes to answer questions 7 through 9 7. Which of the six phase changes would release the largest amount of heat into the atmosphere a. Deposition b. Condensation c. Freezing d. sublimation 8. Which of the six phase changes would extract the most heat from the atmosphere a. Evaporation b. Sublimation c. Melting d. Condensation What phase changes can occur during cloud formation a. Evaporation and condensation b. Sublimation and melting c. Condensation and deposition d. Freezing and sublimation 9.Explanation / Answer
when water changes from liquid to ice , molecule of the water needed less energy to bound togeather. so they released the heat energy in the atmosphere and vice versa in the case of water changes from ice to water. and when water changes from liquid state to gaseous form its molecules needed energy to leave their current state, same phenomenan will use in these questions.
deposition is the phase transition in which gas changes into solid directly without going to the liquid phase. ( (heat released )
sublimation is the phase transition in which soild changes into gas directly without going to the liquid phase. ( heat extract)
freezing is the phase transition in which liquid changes into solid. ( heat release)
condensation is the process when vapor condensed and convert into liquid, fo rthe system whihc is vapor changes into liquid energy released, conversely, when liquid changes into vapor energy absorbed.
evaporation is the phase transition in which liquid changes into gaseous form. ( heat extract)
melting is the phase transition in which solid changes into liquid form. ( heat extract)
1. which of the six phase changes would release the largest amount of heat into the atmosphere?
answer- A) deposition, it is the process in which gas changes into gas directly . when molecule of the gases released our energy into atmosphere, they lost their state and that heat loss is on higher amount thatswhy they convert into solid phase without going to the liquid phase.
2. which of the six phase changes would extract the most heat from the atmosphere?
answer-(B) sublimation, this is the two phase transition at one time from solid to gaseous form , so heat extraction in this process will be higher.
3. whate phase changes can occur during cloud formation?
answer- (A) evaporation and condensation, clouds are the form of water by the evaporation of water and condensed at one place.
