Physical Properties
This property tells how much matter is in an object.
mass
This state has a fixed shape and a fixed volume.
solid
A mixture is made by combining how many substances?
Two or more substances.
A solution is a special type of what?
mixture
Which state of matter can flow and has a fixed volume?
Liquid
A paper clip moves toward a magnet. Which physical property is being observed?
magnetism
This state has a fixed volume but takes the shape of its container.
liquid
True or false: The substances in a mixture keep their identities.
True.
In a solution, are the substances evenly distributed or easy to see as separate pieces?
They are evenly distributed.
A sample has a mass of 509 g. Another sample has a mass of 205 g. What is their total mass when mixed?
714grams
A thermometer reads 24°C. Which physical property is being measured?
temperature
This state expands to fill the container it is in.
gas
Paper clips, glitter, marbles, and colored water are placed into one bottle. Is this a mixture or solution?
Mixture
Lemonade powder is stirred into water until you can no longer see the powder. What has likely formed?
Solution
A 410,999 g sample is mixed with a 246 g sample. What will the total mass be?
411,245grams
Glitter floats while marbles sink in water. Which property could help explain why they behave differently?
density
An ice cube melts on a table. What state does it change from and what state does it change into?
From a solid to a liquid.
A student mixes sand and water. Can you still identify the sand and the water?
Yes. They keep their identities.
A beaker contains water with sand sitting at the bottom. Is this a solution? Explain.
No. The sand is still visible and has not dissolved evenly throughout the water.
A mixture has a total mass of 725 grams. One substance has a mass of 348 grams. What is the mass of the other substance? Show your work and explain how you know.
377 grams
A student says, "The marble sinks, so sinking is a physical property." Explain why this statement is not quite correct.
Density is the physical property that helps explain why an object may sink or float. Sinking is an observation, not the property itself.
An ice cube melts inside a sealed container. Did the amount of matter change? Explain.
No. The matter changed from a solid to a liquid, but the amount of matter stayed the same because matter is conserved.
What is the difference between mixture and solution
The substances in a mixture keep their identities. In a solution the substances do not keep their identities.
True or false: Every mixture is a solution. Explain your answer.
False. A solution is a type of mixture, but not every mixture is a solution.
A container holds a mixture with a total mass of 1,002 grams. The mass of one substance is 578 grams. What is the mass of the other substance? Explain how you know. r.
424 grams
1,002 − 578 = 424 g
