Ideal Gas Law combination

Question 1

What do we get by combining the laws: Boyle’s Law, Charles’ Law and Avogadro’s Law? What is the formula?

Answer 1

We get the combined ideal gas law, which is:

PV = nRT

Where:

P - Pressure
V - Volume
T - Temperature in Kelvin
n is the moles of gas
R is a gas constant, which depends on the units of pressure and volumes

Question 2

What is the standard unit of measurement for volume?

Answer 2

Cubic meters

Question 3

What is the standard unit of measurement for pressure?

Answer 3

Pascals or Kilopascals

Question 4

What is the standard unit of measurement for Temperature?

Answer 4

Kelvin

Question 5

What other units indicate Volume?

Answer 5

Litres

Question 6

What other units indicate Temperature?

Answer 6

Celsius

Question 6

What other units indicate Pressure?

Answer 6

Millimeters (mm)

Question 7

How do you convert Celsius into Kelvin?

Answer 7

If given any value in Celsius, add it by 273 in order to get the value for Kelvin

Question 8

When using the ideal gas law formula, make sure to always use convert Celsius into KELVINS

Answer 8

Fax

Question 9

If the given celsius or Kelvin temperature is under SLC conditions (which is 24.79 Celsius or 297.79 Kelvin, then R will be 8.314)
