matter

Question 1

what are the 3 states of matter?

Answer 1

solid liquid gas

Question 2

what is solid to liquid called?

Answer 2

melting

Question 3

what is liquid to gas?

Answer 3

evaporation/boiling

Question 4

what is gas to liquid?

Answer 4

condensation

Question 5

what is liquid to solid?

Answer 5

freezing

Question 6

what is the movement and arrangement of particles in a solid?

Answer 6

in the solid state the vibrating particles form a regular pattern. this explain the fixed shape of a solid and why it can’t be compressed or poured.

Question 7

what is the movement and arrangement of particles in a liquid?

Answer 7

in a liquid the particles still touch their neighbours but they move around sliding over eachother. this is why you can pour but not compress a liquid.
close packed irregular structure.

Question 8

what is the movement and arrangement of of particles in a gas?

Answer 8

in a gas state, widely spaced particles move around randomly and rapidly. this explains why you can compress a liquid.

Question 9

what happens to the particles in a substance when it is heated up?

Answer 9

when you hear particles they gain energy and move faster, the intermolecular forces can be broken to change a substance to solid –> liquid

Question 10

what happens to the particles in a substance when it’s cooled down?

Answer 10

when they cool down the particles move less and come closer together. more intermolecular forces occur.

Question 11

what is evaporation?

Answer 11

evaporation is also the change of state from liquid to gas that happens at any temperature. it can only happen to particles at the surfaces
