States of Matter
What are the three states of matter?
What happens if you melt Ice (a solid)?
It will melt into a liquid.
What happens in the Water cycle?
The water cycle is when water evaporates and turns into gas, goes up into the sky, forms clouds through condensation, and then falls back down as rain.
What is an atom?
An atom is a tiny, tiny little sphere that makes up everything. Even humans!
What is water, and what 2 elements is it made up of?
Water is a compound, which is when different elements chemically join into one big substance, and it is made up of Hydrogen and Oxygen. Kind of like Hydrogen and Oxygen had a child together (water).
Why can't solids be compressed according to Particle Theory?
The Particles are held together strongly and tightly packed together.
What will happen if you boil water?
What gives energy to the water cycle?
The Sun.
Can atoms be seen?
No, it cannot be seen by the naked eye. It is tinier than MICRO.
What is a mixture and how is it different from a compound?
A mixture is basically like a compound but the elements don't chemically join — it's just different substances put together, and they can still be separated easily.
How can Gas particles be compressed?
They do not touch eachother and are very far apart, they can spread to fill the space they are in and change their shape.
What happens if you heat up a solid, according to Particle Theory?
The Particles will vibrate and go a tiny bit far from eachother.
What happens when water vapour cools down?
It turns into water and makes clouds.
What does atom mean?
What's an alloy?
An alloy is a mixture, but a mixture SPECIFICALLY of metals.
How are liquids able to be poured easily?
Liquid Particles are held together very weakly and are touching eachother. They can also move past eachother.
What happens if you freeze liquid particles?
The particles will eventually lose energy so they cannot move, therefore staying in one place like a solid.
Why does one side of a mountain get more rain?
Because wet air goes up, cools down, and rains on that side.
Are there different types of atoms?
Yes, actually, 94 different types of atoms. 24 of them were made in a lab.
Why are planes made using metal alloys instead of a pure metal?
Because alloys are stronger than the pure element by itself.
What is the only state of matter that can be compressed?
Gasses.
What happens if you melt Solid Particles?
The Particles will eventually get a lot of energy and start wobbling around and moving around like a liquid.
How does cutting trees change the water cycle?
Less trees means less water in air, so less rain happens.
What is an element?
A substance that is made up of one type of atom, like pure 24 carat gold.
