Properties of Materials A
It is a property of a material that lets it absorb water and other liquids.
POROSITY
It is the upward push exerted by a liquid, like water, on an object
BUOYANT FORCE
This is a for of decay on food.
For hazard symbols, what shape indicates WARNING?
DIAMOND
MR. PALMER waited for the class to quiet down.
Mr. Palmer- Noun
Porous materials have plenty of spaces inside where can be absorbed.
LIQUID
The buoyancy of an object is affected by the exerted on it.
BUOYANT FORCE
A tin can with a bulging top is a sign of spoilage for canned goods.
BULGING
Give two examples of TOXIC materials.
INSECTICIDE, PESTICIDE
The floating and sinking of objects do not depend on their sizes. They depend on their .
DENSITY
The decaying process takes place with the help of .
DECOMPOSERS
What illnesses may be experienced by a person who has eaten spoiled food? Give two examples
cholera, diarrhea, poisoning
This is the process of breaking down biodegradable materials into nutrient-rich fertilizer
COMPOSTING
It is the tendency of an object to float or rise when put in liquid.
BUOYANCY
These materials can clog drainage and cause water and land pollution when irresponsibly thrown away
NONBIODEGRADABLE
Why must we refrigerate leftover food?
TO DELAY THE DECAY PROCESS
This is the process of converting nonbiodegradable materials into useful products.
RECYCLING
This property of matter is related to the mass and volume of an object.
DENSITY
You can solve for the volume of objects through the use of the .
WATER DISPLACEMENT METHOD
Give three signs of food spoilage.
molds, bubbles, foul odor
This process converts wastes into energy technology by converting materials into ash, fuel gas, and heat.
