Properties of Matter
This property measures HOW MUCH matter is in an object.
What is mass?
DOUBLE JEOPARDY
True or False: When you pour a can of coke into a glass, the volume changes.
False - The coke still takes up the same space, so its volume is still the same. The SHAPE of the liquid changed.
DOUBLE JEOPARDY
True or False: When ice melts its mass changes.
What is False!
Three common states of matter
What are solids, liquids, and gases?
We measure volume using these metric units (name at least one).
What are milliliters (mL) and cubic centimeters (cm^3)?
The property measures how much SPACE an object takes up.
What is volume?
Cutting paper is an example of a _______ reaction.
What is a physical reaction?
If I add heat to particles, how will those particles begin to change?
The particles will move quicker and will begin to spread apart. If you add heat, the particles do more 'work.' "Heat is work and work is heat."
For anything to be matter, it must do these two things.
What are have mass and take up space?
DOUBLE JEOPARDY
We measure mass using this metric unit.
What are grams?
This property of matter measures the ability of one substance to dissolve into another.
What is Solubility?
Baking a cake is an example of a _____ reaction.
What is a chemical reaction.
The temperature where a solid turns into a liquid because of heat.
What is the melting point?
TRIPLE JEOPARDY
All matter is made out of these incredibly tiny things.
What are particles?
My particles spread apart very easily and quickly. I don't have a definite shape, and my volume can change as well. I am the _________ state of matter.
What is gas (gaseous)?
True or False: Mass and Weight are the same thing.
FALSE!! Mass is a measure of matter, but weight is a measure of gravity pulling on an object. Consider this - if I send you to the moon, your mass does not magically change. Mass stays the same, but the moon's weaker gravity makes you weigh less.
The math formula for finding density (hint: it uses two other properties of matter).
What is mass divided by volume? (mass / volume = density)
The temperature where a liquid turns into a gas because of heat.
What is the boiling point?
My particles hold together and hardly move. I have a definite shape and volume. I am the ___________ state of matter.
What is solid?
My particles stay together, but can also move around. I don't have my own shape, but I have volume. I can be poured. I am the ___________ state of matter.
What is liquid?
This property of matter measures how "tightly packed" an objects matter is.
What is Density?
These type of reactions create a new substance.
What is chemical reaction.
If you cut an apple into slices, has the mass of the apple changed?
The mass has not changed. Even though it has been cut into pieces, if you put them back together, the mass would be the same as when you started!
This state of matter can be found on the sun, in lightning, and in flourescent light tubes.
What is Plasma?
You use this tool to measure an object's mass.
What is a balance? (Also accepting 'scale,' but technically that measures weight - science is weirdly specific, but it'll make sense if you spend enough time with it)
