Matter
- Anything that has mass and occupies space
- includes all living and non living matter
- How do you check the mass of air?
-Set two ballons each filled with air and prick one ballon- The ballon without the air becomes lighter
How to you know if air occupies space
- When you pump air into the ballon- the ballon becomes bigger because air is entering
To check more on Matter, try watching the video below
Matter
3 states of matter- solids, liquid and gas
Video to watch
State of Matter
Density- Mass per unit volume of substance
- measured in grams per cubic centimeter/ kilograms per cubic centimeter
- Objects are able to float due to their density
- If the object is less dense that the liquid- it will float
- If the object is more denser than the liquid- it will sink
Application
- Collecting hydrogen gas- hydrogen gas can be collected by bubbling the gas through the water. Since hydrogen gas is insoluble in water and less dense it will be formed on top of the water.
- Rafts
- Floats and buoys
