Kinetic Theory And Gases

Question 1

What does kinetic theory state

Answer 1

Everything is made of tiny particles

Question 2

What is temperature a measure of

Answer 2

The average kinetic energy in a gas

Question 3

What causes pressure of a gas

Answer 3

The amount of ke in the particles of the gas. The greater the ke, the more they’re moving so they collide more often and harder with the container they’re within causing an outwards force on it, pressure

Question 4

What is the unit of pressure and sign

Answer 4

Pascals, 1Pa = 1N/m^2

Question 5

What is the coldest temperature in Celsius and kelvin and why isn’t there lower

Answer 5

Abosolute 0 and is -273C or 0K. Can’t get colder as it is the temperature of where particles have 0 Ke, so 0 energy therefore can’t get colder

Question 6

What is the relationship between kelvin and pressure

Answer 6

Directly proportional, double one the other also doubles

Question 7

How do you convert kelvin to Celsius and Celsius to kelvin

Answer 7

Kelvin to Celsius, subtract 273 from the kelvin

Celsius to kelvin, add 273 to the Celsius

Question 8

What is the pressure, volume temperature equation

Answer 8

(P1V1)/T1 = (P2V2)/T2

Question 9

What are the rules of the equation

Answer 9

If one of the variables are constant, remove it from the equation
Temperature is always in K and volume in M^2, pressure can be any measurement of pascals
