20.1 Experimental Gas Laws

Question 1

Define PRESSURE

Answer 1

the force per unit area that a gas, liquid or solid at rest exerts normally on a surface

measured in Pascals, Pa

Question 2

Define ISOTHERMIC

Answer 2

the temperature remains constant, so an isothermic change is a change where the temperature does not change

Question 3

What is BOYLE’S LAW?

Answer 3

BOYLE’S LAW states that for a gas at constant temperature with fixed mass that:

pV = constant
PressureVolume of gas = constant

Question 4

What is CHARLES’ LAW?

Answer 4

CHARLES’ LAW States that for a gas of fixed mass and pressure of an ideal gas its volume is directionaly proportional to the absolute temperature

V/T = constant
Volume of gas / Temperature in Kelvins = constant

Question 5

Define ISOBARIC

Answer 5

the pressure of the gas, liquid or solid remains the same, an isobaric change is a change in which the pressure of a substance remains the same

Question 6

Define an IDEAL GAS

Answer 6

any gas that obeys BOYLE’S LAW

Question 7

What is the PRESSURE LAW?

Answer 7

the PRESSURE LAW states that for an ideal gas of constant volume its pressure is directionaly proportional to its absolute temperature

P/T = constant
Pressure / Temperature in Kelvins = constant
