Which of these objects are nonmagnetic?
(You may choose more than one answer.)
iron nail
wooden spoon
aluminum foil
plastic spoon
Which of these substances are soluble in water?
(You may choose more than one answer.)
sand
sugar
cinnamon
salt
You mix baking soda and vinegar. Bubbles form, and the mixture now weighs less. Why did that happen?
It evaporated.
It melted.
The weight changes in a chemical reaction.
A gas formed and escaped.
After you melt some chocolate,
the weight will increase.
the weight will decrease.
the weight will stay the same.
Why would a metal bench outside burn you?
Metal is an electrical insulator.
Metal is an electrical conductor.
Metal is a thermal conductor.
Metal is a thermal insulator.
Why would you not burn your hand on a rope on the playground?
Rope is an electrical insulator.
Rope is an electrical insulator.
Rope is a thermal insulator.
Rope is a thermal conductor.
Why can't you see salt in water?
The salt melts in the water.
The salt is soluble in water, so it dissolves.
The water is not soluble in water, so it dissolves.
The salt no longer exists.
How could you prove water has salt dissolved in it?
Look at the water carefully.
Heat the water so it evaporates and the salt is left behind.
Heat the water and look for bubbles.
Pour the water through a something with holes in it.
How could you calculate the weight of a mixture of different types of juice?
Weigh the ingredients and subtract the weights.
Weigh the ingredients and add the weights.
Heat the juice, so it evaporates.
Use a triple beam balance.
What provides the best evidence that air is made of matter?
measuring the temperature of air
comparing the volume of an empty balloon and an inflated balloon
measuring how long it takes air to escape a balloon
finding the volume of air in spaces by pouring water into the spaces
What is the best evidence that air in a syringe is matter?
You can see through the air in a syringe.
The volume on the syringe says 5 mL.
You can put the syringe on a balance to measure its mass.
You can't push the plunger all the way to the end of the syringe.
What's true about the particles that make up matter?
They're too small to see with only our eyes.
They're always locked in place.
They're only in solids.
They're always the same size.
You have 100 mL of water. You leave it out on a counter and now there are 30 mL left. How much turned into water vapor that went into the air?
130 mL
70 mL
30 mL
100 mL
You heat a solution. When would be evidence that the solution contained matter that could not be seen?
The water level decreased.
The water boiled rapidly.
There were bubbles.
Once the water was gone, you could see white crystals.
What is an example of matter existing but being too small to see?
nuts and raisins mixed in a bowl
rocks and sand mixed on a beach
salt dissolved in water
bricks in a wall
You mix baking soda and vinegar. Bubbles form. Now the mixture weighs less. You think it's because a gas formed and escaped. How could you test if this is true?
Try the experiment again in the exact same way and see if the weight changes.
Try the experiment again but seal it in a bag, so the gas can't escape and see if the weight changes.
Try the experiment again but heat it up.
Try the experiment again but seal it in a bag and don't weigh it.
Which description sounds most like a nonmetal?
shiny and conducts heat well
shiny solid
good at conducting heat and electricity
dull and does not conduct heat well
What is the property when you find the color left by rubbing the mineral on a tile?
color
luster
hardness
streak
A cup of saltwater weighs 145.5 grams. The water weighed 100 grams. The empty cup weighed 35.5 grams. How much did the salt weigh?
150 grams
10 grams
10.5 grams
15 grams
What tool would let you examine the particles that make up matter?
microscope
hot plate
graduated cylinder
triple beam balance
