True or false
The spaces between solids are big.
100
What is False.
100
What is the melting point of ice?
What is 0℃
Is the temperature for ice to melt
100
What is Mass?
A measure of the amount of matter in an object
100
How do the particles move during evaporation?
What is they get farther apart and move freely.
What happens when glass expands?
100
When the Glass expands, the glass will shatter because of the water, which then shatters it.
What is a Liquid?
200
What is a liquid is a substance where particles are slightly farther apart and flow freely.
200
True or false
The boiling point for a liquid changing into a gas is 99℃
What is False, the boiling point is 100℃
200
Define Phase Change.
What is the process of transition of matter from one state to another
200
What is particle movement?
What is particle movement is the movement of particles in a state.
What is thermal expansion?
200
What is the tendency of matter to increase in length, area, and size.
What is a Gas?
300
What is gas is a substance where particles are far apart and can move in any direction.
300
What is a physical change?
What is a change in matter that does not change the chemical composition of the matter/ nothing new is formed
300
What is Sublimation?
What is a process in which a solid substance changes into a gas state
300
What would happen if a movable bridge expanded and there wasn’t enough space between each side?
What is it would get stuck and wouldn’t be able to go up and down when boats come.
What happens when railway tracks expand?
300
When railway tracks are assembled, a slight gap between the tracks is made. When the tracks absorb the heat from the sun, the tracks begin to vibrate
True or false
Are Liquid particles in spaces larger than a solid?
400
What is True
400
What is the term that means turning a solid into a vapour
What is sublimation is when the solid is turned into a vapour[dry ice]
400
What is volume?
What is the amount of space matter takes up
400
Why is there a space between railway tracks?
What is so that when they expand, the railway track won’t buckle.
What happens when metal expands
400
When metal expands, it begins to become larger in width. For example, the DuSable bridge in Chicago began to expand because of very hot temperatures. The bridge began to thermally expand because of the very hot weather, then it began to get stuck, so when the bridge tried to open, it got stuck and it couldn’t open anymore because it was stuck.
Is expired milk a liquid or a solid?
500
What is it still is a liquid.
500
True or false
As the planet gets warmer, the sea levels rise
What is true as the sun heats up oceans, there is thermal expansion, which makes the air particles move faster and expand which makes the sea levels rise
What is the Principle of Conservation of Mass?
What is the total mass of substances that don’t change during a chemical reaction
500
What is a natural disaster that is caused by thermal expansion of liquids?
What is rising sea levels, which could lead to flooding.
What happens when wood expands
500
When wood expands, the wood will become bigger. For example, in the summer when it is very hot, the door will begin to expand, making it harder to open because it is beginning to get stuck, and then it will be harder to open the door.
