True ..............................
One is when you are measuring a distance in space! I don't know the other but hope you find another example!
P=w/t
so the answer is 500/10=50
1. D) Solid
2. C) They are moving at high speeds and are far from each other
3. A) Gas
4.C) diagram C (as gas has the most kinetic energy so it moves and separates the most)
A)Gas (same question as 3)
5.C) melting
6.C) solid
7.D) condensation, energy is removed
8.D) B is Liquid , it’s freezing as energy is removed
9.A) Gas would change to vapour
10.B) Vaporisation
11. A) As temp increases energy of particles increase and substance changes from solid to liquid to gas
12. particles in a solid are more compact than in liquids and gases & solids maintain a fixed volume whereas liquids and gases are able to move more freely and their volume can change
