Fluids and density 1
This term describes how much mass is contained in a given volume of a substance.
What is density?
This word describes anything that has mass and volume.
What is matter?
The change of state from solid to liquid.
What is melting?
This metric unit, written as cm³, is often used to measure the volume of small solid objects.
What are cubic centimetres?
In the particle model, this describes how particles move around.
What is movement (or motion)?
This quantity, measured in grams or kilograms, is the amount of matter in an object.
What is mass?
This term describes the amount of space an object takes up.
What is volume?
The change of state from liquid to solid.
What is solidification?
This unit, written as mL, is commonly used to measure liquid volume.
What are millilitres?
According to the kinetic molecular theory, when energy is removed, particles move this way.
What is slower?
This property is measured in units such as cubic centimetres or millilitres.
What is volume?
This is not considered matter because it does not have mass or volume: heat, solids, water, or oxygen.
What is heat?
The change of state from liquid to gas at the surface of a liquid.
What is evaporation?
The density unit g/cm³ describes the amount of mass in one of these volumes.
What is one cubic centimetre?
According to the kinetic molecular theory, adding energy makes particles move this way.
What is faster?
These substances can flow because they do not have a fixed shape.
What are fluids?
These three familiar forms—solid, liquid, and gas—are called this.
What are states of matter?
The change of state from gas to liquid.
What is condensation?
The density unit g/mL describes the amount of mass in one of these liquid volumes.
What is one millilitre?
This theory explains how particles act when their spacing and movement change.
What is the kinetic molecular theory?
Fluids can flow because they do not have this fixed property of a solid.
What is shape?
In the particle model, this quantity refers to how far apart the particles are.
What is spacing?
The change of state directly from solid to gas.
What is sublimation?
To calculate density, you divide this quantity by the volume.
What is mass?
The total energy of the particles in an object is related to this type of energy.
What is thermal energy?
