States of matter
Name the 3 states of matter
Solid liquid gas
Are the atoms in solids tightly or loosely packed
tightly packed
When something floats does it go above or below another substance
above
What is more dense a feather or a brick
A brick
In which state do the atoms have the most energy
Gas
What happens to the particles when you heat a solid
They start to get more energy/ vibrate more and some solids expand. For example metal.
What is denser water or honey
honey
What is density?
Density is how many particles are packed into an object.
What will happen if you heat the gas in a balloon
The particles will get more energy and push harder on the ballon making it expand.
Which state are the molecules moderately close?
Liquid
Can solids and liquids be compressed?
no
If water has the density of 1g/cm3 and oil has the density of 0.9g/cm3 which will float
The oil will float as it is lighter or is less dense.
how do you calculate density?
divide the mass by its volume
What are the particles called?
Molecules
Do solids take the shape of their container
no they maintain their shape
what is the density of an object if its weight is 10g and its volume is 5 cm3
2g/cm3
How do you calculate Mass?
Density times Multiply
Name the process where a gas turns into a liquid
Condensation
what are more dense liquids or solids?
Solids- particles are closer together
How do you calculate Volume?
D/M
What is the process in which a solid turns in to a gas
Sublimation - remember the dry ice!
