What is the word for:
Changing from gas to liquid
Changing from gas to liquid is called:
Condensation, or to condense
Does the volume of a solid change when it’s put in a container?
a) the volume changes
b) the volume doesn’t change
c) the density changes
b) the volume doesn’t change
Solids must experience a physical or chemical change to change their their volume. Solids have definite volume.
Name two forces that can move objects that are not contact forces.
Gravity and magnetism can move objects without touching that object.
How are solutions and mixtures different?
Mixtures are any two things mixed together, but not dissolved evenly.
Solutions are mixtures that are evenly mixed and dissolved into each other.
How tall is Ms.Yunah?
158 cm
What is the word for:
The amount of matter in an object
The amount of matter in an object is called:
mass
What is the force that helps you run and also stop moving?
a) position
b) distance
c) friction
c) friction
Friction is a force that occurs naturally as two objects rub together.
Give 2 signs of a physical change and chemical change!
*This is a bit of a hard question!
Chemical Changes will show/have:
Form/emit/create of gas
Form/emit/create heat
Form/emit/create light
Physical Changes are:
A change in form. Examples are:
- Rip
- Tear
- Fold
- Broken apart
- Changes in state can also be physical changes
- Liquid water, steam, and ice are all water!
How does gravity affect weight?
Weight is the measure of gravity on a thing.
On the moon, you would weigh less, because the moon has less gravity. (because it is so small!)
100kgs on earth would be about 17kgs on the moon.
On Jupiter, 100kgs would be about 250kgs.
The gravity on Jupiter is so much stronger because Jupiter is so big!
What meat is typically eaten during American Thanksgiving?
Turkey!
What is the word for:
The pull of gravity on an object
The pull of gravity on an object is called:
Weight
What is mass?
a) the amount of atoms in an object
b) the size of an object
c) the gravitational pull of an object
Mass is:
a) the amount of atoms in an object
Mass measures the amount of matter in an object.
What happens to a liquid that has energy taken from it?
Liquid that loses enough energy will freeze and become a solid.
What is the difference between volume and mass?
*A bit of a challenging question!
Volume is how much space a thing takes up!
A bowling ball and a soccer ball have similar volume.
Mass is how much matter is inside of a thing.
A bowling ball has much greater mass than a soccer ball.
What city is Ms.Yunah from?
Boston, MA!
What is the word for:
A mixture when many kinds of matter are evenly mixed in another kind of matter
A mixture when many kinds of matter are evenly mixed in another kind of matter is called:
A solution
If you mix sand into water, you would have a:
a) solution
b) mixture
c) chemical change
b) mixture
A mixture is different kinds of matter mixed together but not dissolved.
A solution is a mixture where matter are mixed evenly and usually entirely dissolved and cannot be filtered out.
Coca Cola is a good example of a solution.
Pizza is a good example of a mixture.
What happens to a gas that has energy taken from it?
Gas that loses enough energy will condense and become a liquid.
When you're ice skating, do you experience more or less friction than when you're walking?
Friction is a rubbing force that will slow things down.
