What's The Matter
What are the properties of a solid?
It has a fixed:
-shape
-volume
-cannot be compressed
-particles are packed tightly together
What term mean how much something can be squished?
Compressibility
Mass is the amount of stuff in an object. Volume is how much space that stuff takes up. So mass is about the amount of matter, and volume is about the space it occupies.
True
Buoyancy is determined by an object's density compared to the density of the water. It this definition true or false?
True
What are the properties of liquid?
Liquids can:
-Change their shape ie) take the shape of the container they are in
-volume is fixed
-cannot be compressed
Everything that takes up space, has weight and is always moving is called...
Fish use something called a ballast tank to swim up and down.
False- They use a swim bladder.
If an object is less dense than the water is it positively buoyant. A rubber ducky is positively buoyant. Is this true or false?
True. A rubber ducky is less dense than water.
What are the properties of gas?
-volume and shape changes
-can be compressed
-particles move around freely
This term means how tightly packed the matter in something is. If something is very _____ , it means a lot of stuff is squished into a small space.
Density
If an object is more dense than the water is it negatively buoyant. A steel spoon is negatively buoyant. Is this true or false?
True
Which state of matter takes the shape of its container?
This term is a force that makes things float in water or air. If something is _____, it can float well.
False- compressed air creates the force in pneumatic tools
What happens to a submarine when we want it to dive deeper?
The ballast tanks fill with water.
What are the 5Physical Properties of Matter?
-State
-density
-mass
-volume
-compressibility
This theory says everything is made up of tiny particles that are always moving. These particles attract each other and have spaces between them.
Particle theory of matter
False-it is more dense.
The ballast tanks fill with gas and water so they are as dense as the water.
