5
Although they are not rigid, fluids can change shape and flow.Intermolecular space is more than solids and ________ is less than solids.
intermolecular force of attraction
New cards
6
DRY ICE
________- When the pressure is reduced to one atmosphere, solid CO2 is immediately transformed to a gaseous state without first entering a liquid state.
New cards
7
________ drops as a result of the water vapour particles being carried away by the wind as wind speed increases, also rate of evaporation is directly proportional to increase in wind speed.
Humidity

8
Liquids
________ can diffuse solids, ________, and gases.
New cards
9
particles
The forces of attraction between the ________ are defeated by the energy provided by heat.
New cards
10
liquid particles
To make up for the energy lost during evaporation, the ________ take energy from their surroundings.
New cards
11
A drop in humidity: The amount of ________ in the air is referred to as humidity.
water vapour
New cards
12
The particles begin vibrating faster as a result of the increase in ________.
kinetic energy
New cards
13
The particles of matter are very small
they are small beyond our imagination
New cards
14
A rise in temperature
with a rise in temperature,more particles have enough kinetic energy to enter the vapour state as a result of rising temperatures so rate of evaporation increases
New cards
15
a drop in humidity
The amount of water vapour in the air is referred to as humidity
New cards
16
a rise in wind speed
It is a well-known phenomenon that clothes dry more quickly on windy days
