What happens when a solid turns into a liquid?
What is It melts?
100
What is thermal energy?
The total kinetic energy of all particles in a substance
100
A measure of the amount of mass in a given volume.
What is Density?
200
In which state of matter are particles tightly packed and have a definite shape and volume?
What is Solid?
200
If an object floats on water, what can you infer about its density compared to water?
What is less dense than water. ?
200
What are the 3 states in the PICTURE above
Solid , LIQUID , GAS
200
Heat always moves from ___________ objects to ___________ objects.
what is Warmer to cooler ?
200
Why does hot air rise and cold air sink?
What is a Hot air is less dense than cold air. ?
300
anything that has mass and takes up space
What is matter?
300
Density describes the relationship between ____ and ____.
mass and volume
300
What phase change occurs when a liquid turns into a gas? TRUE OR FALSE
Evaporation or boiling.
300
Why does a metal spoon feel cold when placed in ice cream?
What is Heat moves from the spoon into the ice cream, cooling the spoon. ?
300
Why do icebergs float even though they’re made of solid water?
What is Ice is less dense than liquid water
400
Which state of matter has particles that move freely and spread out to fill the entire container?
What is Gas
400
Which would have greater density: a small piece of metal or a large piece of the same metal?
What is They have the same density ?
400
Frost forming on a window is what type of phase change
What is Deposition (gas changes directly to solid). ?
400
Which state of matter has the fastest-moving particles?
What is Gas ?
400
Why does a balloon expand when heated?
Gas particles move faster and spread apart, increasing volume.
500
A puddle of water evaporates on a hot day. What does this tell us about the motion of the water molecules?
They gained kinetic energy and moved faster, escaping into the air as gas.
500
An object has a mass of 50 g and a volume of 10 mL. What is its density, and will it sink or float in water?
What is Density = 50 ÷ 10 = 5 g/mL, so it will sink (because it’s denser than water).
500
Explain what happens to the energy of molecules during freezing
What is a Molecules lose energy, move slower, and form a solid structure.?
500
These are examA larger pot of water and a small pot have the same temperature. Which has more thermal energy?
The larger pot, because it has more particles
500
These are examHow can a ship made of steel float even though steel is dense?
The ship’s shape creates air spaces, making its average density less than water.
