kinetic theory Flashcards
1
Q
the particles in a solid, liquid and gas are…
A
all the same size, they are just arranged differently
2
Q
solid
A
neat rows and columns
fixed postion + volume
very closely packed
3
Q
liquid
A
some bonds but less order
takes shape of container
fixed volume
4
Q
gas
A
particles very far apart
move randomly + quickly
gas fills space available (doesn’t have fixed volume)
5
Q
particles in a gas have
A
the most kinetic energy
6
Q
particles in a solid have
A
the least kinetic energy
7
Q
solid - liquid
A
melting
8
Q
liquid - gas
A
evaporating/boling
9
Q
gas - liquid
A
condensation
10
Q
liquid - solid
A
freezing
11
Q
solid - gas
A
sublimation
12
Q
temperature time graph
A
0ºC- y axis
100ºC - x axis
shows melting point and boring point in solid, liquid and gas
13
Q
if you heat a gas, liquid or solid it….
A
expands
