UNIT 2.3 Changing State
Cards in this deck (20)
- 11. What happens when you heat a solid, liquid or gas?It causes its temperature to increase.
- 22. What happens when enough heat is added to a solid?The substance will change its state
into a liquid.
- 33. What happens when enough heat is added to a liquid ?A liquid will change its state into a gas.
- 44. What is melting?The process when heat causes a solid to change states into a liquid.
- 55. What does heat do to the particles in a solid?It makes the particles vibrate and
move faster.
- 66. What is melting point?The temperature at which
a solid will melt into a liquid.
- 77. What is evaporation?The process in which heat causes
liquid water to evaporate.
- 88. Why do clothes dry faster on hot days?The water particles have enough energy from the sun to break free.
- 99. What is sublimation?When a substance changes to it's third stage without having to go into the second one.
- 1010. What is boiling?When a liquid is heated and it
results in bubbling.
- 1111. What is boiling point?The temperature at which
a liquid boils.
- 1212. How are bubbles formed?By evaporation of pockets of liquid
deep inside the liquid itself.
- 1313. What is the boiling point of a substance?It's the temperature at which it changes
from a liquid into a gas.
- 1414. What happens when a substance is cooled?It looses its energy and the particles
move more slowly than before.
- 1515. What happens to a substance if enough heat is removed from a substance?When all of the substance's heat is
removed the substance will eventually
change state. - 1616. What is freezing?When heat is lost and liquid
changes into a solid.
- 1717. What is frost?Liquid water that has frozen overnight.
- 1818. What is the opposite of freezing?MELTING
- 1919. What is condensation?When a gas loses its heat and
changes into a liquid.
- 2020. What is dew?Water vapor that condenses
depending on the temperature.
