Snow and ice formed by water sublimate at below-freezing temperatures
See sublimation in action hang wet cloths outside on a day that temperatures are below freezing. First the water in the cloths will freeze, and then the solid ice sublimates into the air.
Dry ice sublimates from a solid directly to an invisible gas
Deposition occures when the particles of a gas lose energy
Deposition- Attraction between particles locks the particles into rigid structure of a solid. No liquid is formed in the process
Ice crystals form on a cold window when water vapor the air is converted to ice by the process of deposition
same kind of matter- when changes from one state to another
What does change as a result of a change of state? The energy particles, the movement of the particles, and the distance between them change.
Sublimation- solid directly to gas
To change a substance from 1 state to another, energy must be added or removed
Particles in a solid can only move enough to vibrate
Particles in liquid can slide past each other
removing energy from a liquid can cause it to change to a solid as the particles stop sliding past each other
Adding energy to a solid can cause it to change to a liquid as particles begin sliding past each other
solids can change to liquids just as liquids can change to solids
liquid is cooled- has less energy then they did before
Particles in a solid have ordered arrangement
particles slow down, the attractions of between particles increase
Solid- particles are warmed- have more energy then before
temp where liquid change to solid is freezing point. Freezing point of water is 0 degrees Celsius
Solid- particles speed up, attraction between particles decreases
Energy removed at 0 degrees- water converts to frozen state-ice
Eventually particles are able to slide past each other
Freezing point of mercury is -38.8 degrees Celsius. Mercury is still liquid
temp where a solid melts into a liquid is the melting point
All matter is made up of tiny particles in constant motion
During a change of state, the motion of the particles change
Particles can gain more freedom by breaking away from each other
Particles can also attract each other more strongly, and have less freedom to move. This happens when gas changes to a liquid, or a liquid changes into a solid.
A substance must gain energy from the environment or lose energy to the environment
Water to air in clouds-
more freedom
Snows on to a mountain-
less freedom
Snow melts into water-
more freedom
Ice cube melts-
gain of energy
Puddle dries up-
gain of energy
Lake freezes-
loss on energy
Particles in gas have a great deal of energy
Removing enough energy from a gas can cause it to change into a liquid or a solid
Adding enough energy to a liquid or a solid can cause a solid to change into a gas
Liquid is warmed- energy is gained
Evaporation happens more quickly at higher temperatures
The greater the air pressure, the higher the boiling point of a liquid
Boiling- change takes place throughout a liquid, not just at surface
Boiling point of water is 100 degrees Celsius
as liquid is warmed to high enough temperatures, bubbles form
Particles in a gas have very little attraction to one another
at which water boils is called the boiling point
A gas is cooled, its particles lose energy
as air pressure changes at different elevations above sea level, so does the boiling point of liquids
Grass- gaseous water vapor in the air condenses on the cool grass
Contrail is short for condensation trail
Water vapor and soot from when fuel burns in jet engines
change substance from 1 state to another, energy must be added or removed
When a substance gains/losses energy. its temperature changes or its sate changes
Temp remains constant until the change of state is complete
Energy is added when going from a melting point to a boiling point
The temp remains the same until all of a liquid changes into a gas
