Molecules And Ideal Gases

Question 0

Brownian motion

Answer 0

Kinetic energy in the water causes the pollen to move randomly as the waters motion influences the pollen grand motion depending on the amount of kinetic energy present (temperature)

Question 1

How does a gas exert pressure on the walls of its container

Answer 1

The gas particles collide randomly on the walls of the container. They exert some force on a certain area of the wall, creating pressure: p=f/a. They then change direction after the collision with the wall.

Question 2

State Boyle’s law

Answer 2

For a fixed mass of gas at a constant temperature, pressure and volume are inversely proportional to each other

Question 3

Boyles’s law equation

Answer 3

P (inversely proportional sign) 1/v
P = constant/v
pv = constant
P(1)V(1) = P(2)V(2)

Question 4

Why is 0 Kelvin described as absolute zero

Answer 4

There is no more energy available, so you cannot cool down the gas anymore

Question 5

What is the Celsius equivalent to absolute zero

Answer 5

-273

Question 6

What equation is used to convert between the two temperature scales

Answer 6

k - 273 = Celsius

Question 7

As temperature increases in a gas so does

Answer 7

The pressure and speed of molecules but not the volume

Question 8

What is the pressure law

Answer 8

For a fixed mass of gas at a constant volume, pressure and temperature are directly proportional to each other (when the temperature is in Kelvin)

Question 10

Pressure law

Answer 10

P(1)/T(1) = P(2)/T(2)
