1. There are spaces between atoms
Which state of matter has the most amount of space between particles
Gas
Which state of matter has the strongest attractive force
Solids
Which states of matter contain vibrational energy
Solids, Liquids and Gases
When heat is applied to a solid it changes to what state of matter
Liquid
What state of matter fits the following description:
It changes shape to that of its container but its volume does not change
Liquid
State whether the following is a compound, molecule or both.
CO2
Compound and Molecule
What is happening when perfume can be smelt in any area of a room when only sprayed in a corner
Diffusion
When heat is applied to a liquid it... (the answer is a single word)
Evaporates
Which State of matter is hardest to compress
Solid
A new substance is created
What are the three forms of kinetic energy found in molecules
Vibrational, Translational and Rotational
What is the relationship between temperature and pressure of gases
As you increase the temperature you increase the pressure of a gas contained within a finite volume
What is name of the process that describes a gas transitioning to a liquid
Condensation
Explain the relationship between pressure and volume
Your answer should be similar to these statements
- As pressure increases volume decreases
- if the volume is doubles the pressure is halved
- If the pressure of doubled the volume is halved
Using scientific vocabulary Describe the process of diffusion
You answer must be: particles moving from areas of high concentration to low concentration.
Why does adding heat change a substances state of matter
Your answer needs to be similar to the following:
- When heat is added to a substance, the molecules and atoms vibrate faster.
- As atoms vibrate faster, the space between atoms increases.
- The motion and spacing of the particles determines the state of matter of the substance.
Explain why Popcorn pops when heated
Your answer must have contained the following:
- The reasons popcorn pops is that there is water inside the corn.
- When you heat it, the water turns to steam.
- As the pressure increases, the corn explodes.
Explain the process of dissolving a sugar into water
You answer must have contained:
- Sugar has a greater attraction to water than to itself
- The sugar crystals break apart and bond with the water molecules
given that particles are always moving. Describe the relationship between volume, pressure and the number of collision between moving particles
As the the volume decreases, the pressure and collisions between particles increases
Explain why increasing temperature increases how much solvent can be dissolved.
