A
How many states of matter are there?
Three
What are the 3 States of Matter?
Solid, Liquid & Gas
Which 2 states of matter will take the shape of the container that it is in?
Gas and Liquid
What is Evaporation?
The process by which a liquid changes into a gas
What is Condensation
List any 2 of the 4 ideas of the particulate theory of matter
1. Matter is made up of tiny particles. 2. There is a force of attraction between the particles. 3. There are spaces between the particles. 4. The particles are always moving.
How does an increase in temperature causes particles to behave?
Particles will gain more energy to move around faster
How does a decrease in temperature causes particles to behave?
Particles will begin to lose energy, move slowly and become compact
If particles are always moving, why does a solid maintain its shape? How do the particles in a solid move?
Particles in a solid move by vibrating against each other. There is a very strong force of attraction between the particles in a solid.
Name of the process by which a SOLID changes directly to a GAS without becoming a liquid
Sublimation
Name of the process by which a GAS changes directly to a SOLID without becoming a liquid
Deposition
Perfume sprayed at one end of a classroom will spread out to the rest of the classroom. Will the temperature of the classroom affect how fast the perfume spreads out? Explain your answer
Yes. perfume sprayed in a hot classroom will spread out faster than that in a cold classroom since higher temperatures will cause the particles of the perfume to gain more energy and move about faster
Jaymar puts his drink in the freezer to stay overnight. When he checks in the morning the drink is hard as a rock. Explain to Jaymar what happened to the particles in the drink that caused it to become a solid.
The low temperature in the freezer caused the particles in the drink the lose energy, slow down and become compact by moving closer to each other.
Krystal hates when her ice-cream is runny and starts to mess up the cone. She can't seem to understand why when it leaves the freezer it starts to drip and become a liquid. Explain to Krystal what happens to the particles in the ice-cream to cause this change.
Th temperature increases as soon as the ice-cream leaves the freezer. This causes the particles in the ice-cream to gain energy and start to move apart from each other turning it into a liquid.
