Matter
Anything that has mass and takes up space
Matter
What is the physical property of matter that shows an object's resistance to scratching, bending, or denting?
Hardness
This chemical property of matter is measured by finding the pH of an object.
Acidity
The particles in this state are closely packed and vibrate in place.
Solid
To change states, you have to add or remove _____.
Heat
NOT matter, like heat and light
Energy
What is the physical property of matter that shows how an object floats or sinks?
Buoyancy
The pH of a liquid is 2. Is it an acid or a base?
Acid
The particles in this state of matter slide past one another and have a definite volume but not a definite shape.
liquid
This is what happens when a solid changes into a liquid.
Melting
The amount of matter in an object
Mass
This physical property of matter shows how something dissolves in a liquid.
Solubility
The pH of a liquid is 9. Is it an acid or a base?
Base
The particles on this state of matter bounce all over the place and are far apart.
Gas
This is what happens when a liquid changes into a solid.
Freezing
The amount of space that an object takes up
Volume
There are three physical properties of matter that you would use your senses to identify. Name one of them.
Color, odor, texture
These properties of matter do not change the object.
Physical properties
This state of matter has no definite volume and no definite shape.
Gas
This is what happens when a gas changes into a liquid.
Condensation
What is the density of this liquid if the mass is 100 grams and the volume is 50 milliliters. D= M/V
Density = 2 g/ml
This physical property of matter is an equation of the mass divided by the volume of an object.
Density
These properties of matter change an object.
Chemical properties
This substance is weird because when it is a solid it is less dense than when it is a liquid, so it floats in solid form.
Water or ice
This is what happens when a liquid changes into a gas.
Evaporation
