Question 1

Boyles law

Answer 1

‘The volume of a fixed amount of gas maintained at constant temperature is inversely proportional to the gas pressure’
volume is halved then pressure is doubled.

Question 2

Charles’s Law

Answer 2

‘The volume of a fixed amount of gas maintained at constant pressure is directly proportional to the absolute temperature’
if temp is doubled, kinetic energy density doubles and so does pressure

Question 3

Avogadro’s Law: The Volume-Amount Relationship

Answer 3

‘At constant pressure and temperature, the volume of a gas is directly proportional to the number of moles of the gas present’

Question 4

Dalton’s Law of Partial Pressures:

Answer 4

‘The total pressure of a mixture of gases is just the sum of the pressures that each gas would exert if it were present alone’
Ptotal= Pa+Pb

Question 5

What is an ideal gas

Answer 5

A theoretical gas composed of many randomly moving point particles that aren’t subject to inter‐particle interactions.
A gas whose properties obey the ideal gas law is known as an ideal gas.

Question 6

Electron affinity

Answer 6

is defined as the change in energy (in kJ/mole) of a neutral atom (in the gaseous phase) when an electron is added to the atom to form a negative ion.

Question 7

scientists is associated with the development of a quantitative scale of electronegativity?

Answer 7

Linus Pauling
