The ideal gas equation

Question 1

What is the ideal gas equation?

Answer 1

PV = nRT

Question 2

What is the value of R in the ideal gas equation?

Answer 2

The value of R is 8.314

Question 3

What is the equation used to calculate pressure, relating to the ideal gas equation?

Answer 3

P = nRT divided by V

Question 4

What is the equation used to calculate volume, relating to the ideal gas equation?

Answer 4

V = nRT divided by P

Question 5

What is the equation used to calculate number of moles, relating to the ideal gas equation?

Answer 5

n = PV divided by RT

Question 6

What is the equation used to calculate the number of moles, relating to the ideal gas equation?

Answer 6

T = PV divided by nR

Question 7

Volume can be measured in dm cubed and cm cubed, but when using the ideal gas equation metre cubed is preferred.

How do you convert dm cubed to metre cubed?
How do you convert cm cubed to metre cubed?

Answer 7

To convert dm cubed to metre cubed you multiply by 10 to the power of negative three

To convert cm cubed to metre cubed you multiple by 10 to the power of negative six

Question 8

Pressure can be measured in kPa and MPa, but when using the ideal gas equation Pa is preferred.

How do you convert kPa to Pa?
How do you convert MPa to Pa?

Answer 8

To convert kPa to Pa you multiple by 10 to the power of 3/ by 1000

To convert MPa to Pa you multiple by 10 to the power of 6/ by 1 000 000

Question 9

How do you convert degrees celsius to kelvins?

Answer 9

To convert degrees celsius to kelvins you add 273 to the original number (in the degrees celsius)
