EQUATIONS AND LAWS

Question 1

The equation linking pressure, force and area:

Answer 1

Pressure= force/area

Question 2

What is the equation used to calculate pressure in water?

Answer 2

Pressure= density x depth x gravitational field strength

Question 3

What is the conversion between Kelvin and Celcius?

Answer 3

Kelvin -> celcius = -273

Celcius -> Kelvin = +273

Question 4

What does the pressure law state?

Answer 4

“The pressure of a gas and the temperature are proportional when the number of particles and volume remain constant.”

Question 5

What equation links pressure and temperature?

Answer 5

P1/T1 = P2/T2

Question 6

What does Boyle’s law state?

Answer 6

Pressure and volume are inversely proportional when the temperature and number of particles are the same.

Question 7

What equation links volume and pressure?

Answer 7

P1V1 = P2V2

Question 8

What does Charles’ law state? (not on spec)

Answer 8

The volume of a gas and the temperature are proportional when the number of particles and the pressure is constant.

Question 9

What equation links volume and temperature?

Answer 9

V1/T1 = V2/T2
