How Are Pressure and Volume Related?

Week 7
Page 56-57

Multiple Choice

What is volume?

• The applied force on a surface

• The space that an object occupies

• The relationship between pressure and force

• The state of matter of an object

Multiple Choice

What is the relationship between volume and pressure?

• Proportional

• Inversely proportional

• Unrelated

• Random

Multiple Choice

How does the surface area of an object affect pressure?

• Larger surface area exerts more pressure

• Smaller surface area exerts more pressure

• Surface area does not affect pressure

• Surface area only affects volume

Multiple Choice

• Solid

• Liquid

• Gas

• Plasma

Multiple Choice

How is pressure calculated?

• P = V/A

• P = F/V

• P = F/A

• P = V/F
