First Nine Weeks Review Physical Science

Density is a measure of the amount of mass in a given volume. What tool could we use to determine the density of an object?

• scale

• calculator

• ruler

• graduated cylinder

What make physical properties different from chemical properties?

• physical properties relate to elements and compounds

• physical properties appear only after a chemical change occurs

• physical properties can be observed without changing the identity of the substance

• physical properties describe elements in the solid state

gas particles changing states to solid particles is a physical change rather than a chemical change because

• the particles get smaller

• the volume of the matter decreases

• the composition of the matter stays the same

• the particles change into particles of a different substance

What happens to the mass of yogurt when it melts?

• the mass evaporates

• No mass is lost during a change of state

• the mass will increase if he freezes the melted ice cream

• Mass is lost only during certain changes of states

Which type of mixtures are easily seen through, made up a a solute and solvent

• colloid

• solution

• suspension

Which type of mixture is a mix of liquid and solid particles that do not dissolve and will settle over time?
