How are Kinetic Energy and heat related to phase changes?
heat increases kinetic energy i.e. motion of the particles leading to bond breakage which ultimately causes phase change
What happens in the phase change of condensation?
In the condensation phase change, a gas cools (loses energy) and changes to a liquid. Example: water vapor turns into liquid rain.
How do you describe each phase change?
Endothermic phase changes - the substance is gaining energy (being heated) and the molecules are getting more active.- solid to liquid: melting- liquid to gas: vaporization- solid to gas: sublimationExothermic phase changes - the substance is losing energy (cooling) and the molecules are slowing down.- gas to liquid: condensation- liquid to solid: freezing- gas to solid: depositionMemory helper: exo is like exit, and the heat energy exits the substance during an exothermic phase change.
What is the energy absorbed by one gram of water as it changes from its liquid phase into water vapor known as?
The heat of vaporization. :D
What are the phase changes of matter?
The melting phase changes are Solid~Liquid~Gas and the freezing phase changes are Gas~Liquid~Solid
What are the phase changes that release energy?
Condensation
Which phase changes are endothermic?
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
What phase changes require the addition of energy?
Phase changes requiring the addition of heat energy are the phase changes from solid to liquid, liquid to gas, and solid to gas. These phase changes are termed melting (solid to liquid), evaporation (liquid to gas), and sublimation (solid to gas).
Do substances absorb or release heat energy as then change from a liquid to the solid phase?
When a substance changes from a liquid to a solid it releases energy. (You take the heat out)
A great amount of water vapor changes phase to become liquid water droplets in the clouds that form a thunderstorm Does this phase change release energy or absorb it?
a great amount of water vaptor change phase to become liquid water droplets in the clouds that form a thunderstorm. does this phase change release or absord energy? how do you know
What phase changes involve the release of heat?
The phase changes that involve a release of heat are those in which the particles move closer together. Thus, freezing is one phase change that involves a release of heat. The other such change is condensation.
Where does the thermal energy go in such endothermic phase changes?
It is converted to bond energy
What always accompanies a phase change?
Heat energy changes.
When Water loses energy when it changes phase from?
Liquid to solid
Is bond formation an energy absorbing or an energy releasing process?
Bond formation most often releases energy. but if other reactions or phase changes that release energy occur at the same time, bond formation can absorb energy.
What is unique about temperature during phase changes?
It doesn't change notwithstanding heat energy changes.
Describe how phase changes of water transfer thermal energy?
