Pressure

Question 1

What is pressure?

Answer 1

Pressure is the force applied per unit area on a surface.

Question 2

What is the formula for pressure?

Answer 2

P = F / A

Where P = pressure, F = force, A = area.

Question 3

What is the formula for change in volume?

Answer 3

ΔV = A × d

Where ΔV = change in volume, A = area, d = distance moved by piston.

Question 4

What is pressure measured in?

Answer 4

Pascals (Pa), where 1 Pa = 1 N/m².

Question 5

What is work done measured in?

Answer 5

Work done is measured in joules (J).

Question 6

Fill in the blank: Pressure is measured in _______.

Answer 6

Pascals

Question 7

What does 1 Pa equal in terms of force and area?

Answer 7

1 Pa = 1 N/m².

Question 8

In terms of a piston moving inside a cylinder, what is the formula for distance?

Answer 8

d=ΔV​ / A

Question 9

What is the formula for change in volume?

Answer 9

ΔV= A × d
