What does it matter?
This is the form of matter that has a definite shape. It's also the form that has the least amount of energy.
What is a solid?
Well that's just the equation for density. Funny how all you need is mass and volume.
What is D=M/V?
Some examples of this type of change would be ice melting, chopping wood, drying laundry and cutting paper.
What is a physical change?
It's the simplest, most fundamental form of matter there is.
What is an element?
It's what happens to a liquid when it gets too cold.
What is freezing?
It's the form of matter that will spread out until it hits the walls of its container and has no definite shape. It also has the second most energy of all the states of matter.
What is a gas?
If 10mL of water has a mass of 10g, what is the density of water? (Don't think too hard now...)
1g/mL
It's the type of change that occurs when you pour vinegar into baking soda for your model volcano.
What is a chemical change?
This is a mixture that has a uniform composition. Everything is evenly distributed and it all looks the same.
What is a homogenous mixture?
If the pool in your back yard constantly needs to be topped off, you can blame this phase change.
What is evaporation?
It's not too hot, and not too cold, but just the right temperature to drink. It also takes the shape of it's container.
What is a liquid?
It may seem strange, but air has density too. If 700L of air has a mass of 903g, what is the density of air?
903 / 700 = 1.29g/L
It's a measure of the amount of energy the tiny particles in any substance has. An increase in energy, will result in an increases in this.
What is heat?
One example would be C6H12O6.
What is a compound?
It's the phase change responsible for fogging up your bathroom mirror after a shower.
What is condensation?
It consists of charged particles flying around at incredible speeds. It has the most energy of all the types of matter, and is the most abundant type in the Universe.
What is plasma?
Jello has a density of about 1.3g/mL. If I have 12 mLs of jello, what is its mass?
1.3 * 12 = 15.6g
Common signs of this type of change are: Releasing a gas, emitting light, making a sound, heating up, changing color and producing a smell.
What is a chemical change?
Carbon (C), Nitrogen (N), Oxygen (O) and Hydrogen (H) are a few common examples.
What are elements?
It's not a very common phase change, because changing something from a solid directly to a gas requires a lot of energy.
What is sublimation?
Named after the scientist who penned the laws of motion, this type of liquid has unusual properties, like becoming more viscus when pressure is applied. They are also kinda fun to make in a lab!
What are non-Newtonian fluids?
Steel has a density of almost 9 g/mL. If I have 72g of steel, what is the volume of steel I have?
72 / 9 = 8mL
It's the kind of change you see when water boils. (physical or chemical?)
What is a physical change?
It's the type of mixture that doesn't look the same throughout. Like a bowl of mixed vegetables, or oil and water.
What is a heterogenous mixture?
A common example of this phase change happens when water vapor (a gas) contacts a cold pane of glass and immediately turns into frost (a solid).
What is deposition?
