100
This happens when an object is less dense.
What is float?
100
This state of matter has a definite shape and definite volume. Its molecules vibrate in place.
What is a solid.
100
This is the ability or inability of a substance to combine with or change into a new substance.
What is a chemical property?
100
1. This is the amount of matter in an object. ___________________________. Bonus: You use a ____________________ to measure it.
What is mass? Bonus: What is a scale?
100
This is how you measure the volume of a cube/rectangular solid.
What is L x W x H? (cm3)
200
This happens when an object is more dense.
What is sink.
200
This state of matter does not have a definite shape, but does have a definite volume. Its molecules slide past each other.
What is a liquid.
200
This is anything that has mass and takes up space.
What is matter?
200
This is the ability of one material to dissolve in another.
What is solubility?
200
This is how do you measure the volume of an irregular solid.
What is water displacement? First you measure a certain volume of liquid in a graduated cylinder. Next, you place the object in the water. Then, you measure the new volume. Last, you get the difference- this is the volume of the solid.
300
This is how you calculate density.
What is mass divided by volume.
300
This state of matter has an indefinite shape and an indefinite volume.
What is gas.
300
This is any characteristic of a material that you can observe without changing the identity of the material.
What is a physical property?
300
This is the condition or physical property of matter (hint: solid, liquid, gas).
What is state of matter?
300
The sides of the cube are 4. THis is the volume.
What is 4 x 4 x4?
400
This is an ability for an object to float.
What is buoyancy?
400
You need to add or remove this to cause a change of state.
What is heat/energy.
400
A change in the size, shape, form, or state of matter in which the matter’s identity stays the same.
What is a physical change?
400
This is the amount of space a material occupies (takes up).
What is volume?
400
The mass of an object is 40 g. The volume of an object is 20 cm3. This is its density.
What is 2 g/cm3?
500
This is the density of water.
What is 1 g/cm3?
500
When you add heat to a substance, this happens to its molecules.
What is move faster and farther apart (expand).
500
A change in matter in which the substances that make up the matter change into other substances.
What is a chemical change?
500
This is the mass per unit volume of a substance.
What is density?
500
An object has a density of 2.5 g/cm3. You place it in water and this is what happens.
What is sink?
