1a states of matter

Question 1

understand the three states of matter in terms of the arrangement, movement and energy of the particles

Answer 1

.Gas:​ ​particles​ ​have​ ​the​ ​most​ ​energy​ ​–​ ​shown​ ​by​ ​the​ ​diagram,​ ​as​ ​the​ ​particles​ ​are the​ ​most​ ​spread​ ​apart​ ​with​ ​a​ ​random​ ​arrangement
.Liquid:​ ​particles​ ​have​ ​more​ ​energy​ ​than​ ​those​ ​in​ ​a​ ​solid,​ ​but​ ​less​ ​than​ ​those​ ​in​ ​a gas​ ​and​ ​the​ ​particles​ ​are​ ​closer​ ​together​ ​but​ ​have​ ​a​ ​random​ ​arrangement
.solid​ ​has​ ​least​ ​energy​ ​–​ ​particles​ ​are​ ​not​ ​moving/are​ ​just​ ​vibrating​ ​and​ ​they​ ​are arranged​ ​regularly​ ​and​ ​very​ ​closely​ ​together

Question 2

melting

Answer 2

solid to liquid

Question 3

freezing

Answer 3

liquid to solid

Question 4

boiling

Answer 4

liquid to gas

Question 5

condensing

Answer 5

gas to liquid

Question 6

sublimation

Answer 6

solid to gas

Question 7

diffusion

Answer 7

Movement​ ​of​ ​particles​ ​from​ ​an​ ​area​ ​of​ ​high​ ​concentration​ ​to​ ​an​ ​area​ ​of
low​ ​concentration

Question 8

solvent

Answer 8

​liquid​ ​in​ ​which​ ​a​ ​solute​ ​dissolves

Question 9

solute

Answer 9

​substance​ ​that​ ​dissolves​ ​in​ ​a​ ​liquid​ ​to​ ​form​ ​a​ ​solution

Question 10

solution

Answer 10

​mixture​ ​formed​ ​when​ ​a​ ​solute​ ​has​ ​dissolved​ ​in​ ​a​ ​solvent

Question 11

saturated solution

Answer 11

solution​ ​in​ ​which​ ​no​ ​more​ ​solvent​ ​can​ ​be​ ​dissolved
