Ideal Gas Equations:

Question 1

What is the ideal gas equation?

Answer 1

= pressure x volume= moles x ideal gas constant x temperature

Question 2

What is the pressure units and the ideal conversion?

Answer 2

= Measured in pascals (1 pascal is low pressure)
= to convert kPA into PA we multiply by 1000

Question 3

What is the volume units and the ideal conversion?

Answer 3

= Measured in m^3
= to convert cm^3 into m^3 we divide by a million (x 10^-6)
= to convert dm^3 into m^3 we divide by a 1000

Question 4

What is the temperature units and the ideal conversion?

Answer 4

= Measured in Kelvins
= to convert celcius to Kelvin we add 273
= to comvert Kelvin to celcius we take away 273

Question 5

What is the ideal gas constant?

Answer 5

= 8.314 J mol-1 k-1

Question 6

What are the assumptions that we make for an ideal gas?

Answer 6

= gas molecules are tiny compared to the spaces between them
= no forces acting between the gas molecules
= gas molecules move randomly
= when the gas molecules collide,the collisions are elastic

Question 7

What are some points about ideal gases?

Answer 7

= no such thing as an ideal gas
= work well for many gases under these conditions
