States of Matter

Question 1

STP

Answer 1

Standard temperature and pressure
273 K and 1 atm

Question 2

Boyle’s Law statement

Answer 2

Volume of a given mass of gas is inversely proportional to pressure provided that the temperature remains constant

V ∝ ¹ ⁄ P

Question 3

Charles’ Law statement

Answer 3

The volume of a given mass of gas is directly proportional to temperature at constant pressure.

V ∝ T

Question 4

Absolute zero: definition

Answer 4

The lowest possible temperature at which all gases are supposed to occupy zero volume is called absolute zero. (0 K)

Question 5

Absolute scale of temperature

Answer 5

The scale on which the 0 does not depend on any particular property of any particular substance is the Absolute scale or Kelvin scale

Question 6

Gay Lussac’s Law

Answer 6

At constant volume, the pressure of a gas increases or decreases by 1/273 of its volume at 0 degree celsius for every 1 degree celsius rise or fall in temperature

Question 7

Avogradro’s Law

Answer 7

Equal volume of all gases contain equal number of molecules under similar conditions of temperature and pressure

Question 8

Graham’s Law

Answer 8

At constant temperature and pressure, the rate of diffusion of a gas is inversely proportional to the sqrt of its density
