CH. 1.1 - GASES

Question 1

describe how a solid objects particles are arranged and how they behave.

Answer 1

• particles are locked into a fixed position (like a grid)
• they possess vibrational energy

Question 2

describe how a liquid substance’s particles are arranged and how they behave.

Answer 2

• particles take the shape of its container and are arranged in a random way
• some attraction between particles allowing them to move around

Question 3

describe how a gas substance’s particles are arranged and how they behave.

Answer 3

• particles are widely spaced and randomly arranged
• in constant motion

Question 4

Explain Boyles Law: P₁V₁=P₂V₂

Answer 4

If temperature and moles of gas remain constant, volume and pressure have an inverse relationship (if volume goes up, pressure goes down, etc.)

Question 5

Explain Charles Law: V₁/T₁ = V₂/T₂

Answer 5

If moles and pressure remain constant there is a linear relationship between temperature and volume (if temp goes up, volume goes up, etc.)

Question 6

Explain Avagadro’s Law: V₁/n₁ = V₂/n₂

Answer 6

If if temperature and pressure remain constant there is a linear relationship between # of moles and volume

Question 7

What is the ideal gas law?

Answer 7

PV=nRT
- formula that relates pressure, volume and temperature of ideal gases
