Ideal Gases

Question 1

What are the ideal gas laws?

Answer 1

1) gas particle size is so small compared to total volume, so gases are mostly empty space
2) gas particles constantly moving in a straight live until they collide wt smt and bounce in diff. directions
3) when gas particles collide wt amt, no energy is lost (collisions are elastic)
4) no attraction or repulsion btw gas particles

Question 2

When are ideal gas equations not valid?

Answer 2

if the temperature is low or there are high pressures

Question 3

How do you convert celsius into kelvin?

Answer 3

+ 273

Question 4

What is the relationship btw pressure and volume?

Answer 4

inversely proportional

Question 5

What is the pressure volume equation?

Answer 5

P1V1 = P2V2

Question 6

What is the relationship btw pressure and temperature, and volume and temperature?

Answer 6

both are directionally proportional

increased temp = increased kinetic energy, increased collisions, increased pressure

Question 7

What are the pressure, volume, temperature equations?

Answer 7

P1/T1 = P2/T2 V1/T1=V2/P2 P1V1/T1 =P2V2/T2

Question 8

What is the ideal gas law equation?

Answer 8

PV = nRT

P = pressure in KPa
V = volume in dm3
n = moles
R = universal gas constant = 8.314
T = temperature in K(elvin)

Question 9

What are the pressure unit conversions?

Answer 9

atm = atmospheric pressure

1000 Pa = 1 KPa
1 atm = 1000 KPa
