How are physical properties used to identify substances?

a) Physical properties do not identify substances

b) Physical properties are characteristics of substances that can be observed or measured without changing the substance, which helps us to identify and classify matter

c) Physical properties can be changed, so it makes it hard to identify matter and it’s characteristics

O

b) Evaporation – when a liquid becomes a solid

c) Freezing – when a gas changes to a liquid

d) All of the above

gasd) All of the abovee) Both B and Cf) None of the aboveO

Which is an example of a physical change?

a) Melting – when a solid becomes a liquid

b) Evaporation – when a liquid becomes a gas

c) Freezing – when a liquid becomes a solid

d) Condensation – when a gas becomes a liquid

e) A, B, and D

f) All of the above

g) None of the aboveO

How are mass and weight different?

a) Mass can change, weight cannot

b) Weight can change, mass cannot

c) Mass and weight have nothing to do with matter

d) Nothing; they’re exactly the same

O

What are two different methods of finding the volume of an object?

Formula = Length X Width X Height

Water Displacement Method

How do you find density?

a) L x W x H

b) Mass Volume

c) Water Displacement Method

d) With a triple beam balance

__..O

Why are the freezing point and the melting point the same?

• As temperature lowers, it hits the freezing point of a liquid and it becomes a solid.

-- 0º C0º C --

•As temperature rises, it hits the melting point at the same point it began to freeze, and the solid becomes a liquid.

Why does a rock sink when put in water?

a) It has more volume than the water

b) Rocks don’t like to float

c) The rock is more dense than the water

d) Rocks don’t sink in water.

O

What property of water causes water to defy gravity and travel

up through a paper towel?

a) Absorption

b) Volume

c) Density

d) Capillary actionO

What makes water collect on the outside of a cold glass of water

on a hot day?

a) Condensation – the gas particles in the air around the gas, slow down, change state, and become a liquid

b) Evaporation – the liquid in the gas becomes a gas

c) Melting Point – the glass begins to melt

d) Melting Point – the solid inside the glass becomes a liquid on the outside of the glass

O

What property of water allows water to be soaked up into a paper towel when

wiping up a spill?

a) Absorption

b) Volume

c) Density

d) Capillary Action

O

What property allows you to smell popcorn popping when 4th grade is

having a popcorn party?

a) Absorption

b) Dissolving

c) Diffusion

d) OsmosisO

What property of water allows a dome of water to form over the edge of a glass when you add more water to a

glass that is already full?

a) Saturation Point

b) Surface Tension

c) Adhesion

d) Solvent

O

Why were you able to smell vanilla from inside a balloon?

a) Osmosis – when particles escape from a permeable/semi-permeable material

b) Diffusion – when matter travels from a high concentration to a low concentration

c) Surface Tension – when particles are as close as possible, forming a skin

d) Solvent – liquid substance capable of dissolving other substances

O

What will happen when you place a sugar cube into a cup of

water?

a) It will float to the top of the water

b) It will sink to the bottom of the water

c) It will dissolve into the water

d) Nothing will happenO

What is the difference between diffusion and osmosis?

a) Diffusion is the liquid that dissolves a substance; osmosis is the substance that dissolves

b) Diffusion involves a water based substance and travels through a semi-permeable material, while osmosis travels through air molecules, until molecules are evenly distributed.

c) Osmosis involves a water based substance and travels through a semi-permeable material, while diffusion travels through air molecules, until molecules are evenly distributed

d) Osmosis and diffusion are the same thing

O

What is the difference between a solvent and a solute?

a) A solvent travels through a semi-permeable material, while a solute travels through air until the molecules are evenly distributed

b) A solvent dissolves a substance, and a solute is the substance being dissolved

c) A solute dissolves a substance, and a solvent is the substance being dissolved

d) Solute is sugar and solvent is salt.
