important general knowledge

Question 1

why does a real gas deviate from the ideal gas the most under high pressure

Answer 1

this is because at high pressures, the gas particles are compressed together, therefore allowing for the intermolecular forces to be effective enough and the particles to become attracted to each other

Question 2

at lower temperatures why do gasses deviate from ideal gas law

Answer 2

this is do to the molecules moving slowly, which strengthens the intermolecular forces operating between atoms or molecule. Furthermore, lower kinetic energy results in stronger intermolecular forces.

Question 3

why is the ideal gas equation important

Answer 3

it is important because it relates pressure, volume, amount of moles and temperature all together

Question 3

what happens to solubility of a gas as you increase temperature

Answer 3

gasses already have high amount of kinetic energy so an Increased temperature causes an increase in kinetic energy. The higher kinetic energy causes more motion in the gas molecules which break intermolecular bonds and escape from solution

Question 3

what happens to the solubility of solid as you increase the temp

Answer 3

The increase in kinetic energy that comes with higher temperatures allows the SOLVENT molecules to break apart the SOLUTE molecules that are held together by intermolecular attractions.

Question 4

condensation

Answer 4

gas to liquid

Question 5

deposition

sublimation

vaporisation

Answer 5

gas to solid (frost on window)

solid to gas (disappearing snow flake)
Liquid to gas

Question 6

n = N/nA

Answer 6

this makes sense as you can find moles by dividing number of particles over avagradros number
