Question 1

Operating parameters of an ideal gas

Answer 1

Low P high T
Will cause higher volume therefore intermolecular distances is greater and will less intermolecular attractive forces

Question 2

The Kinetic-Molecular theory of gases assumes that the ideal gas molecules:

Answer 2

are constantly moving,
have negligible volume,
have negligible intermolecular forces,
collide perfectly elastically, and.
have an average kinetic energy proportional to the absolute temperature of the ideal gas.

Question 3

Absolute temp

Answer 3

All molecules stop moving
It cannot be achieved
0k
0R

Question 4

Endothermic

Answer 4

Evaporation as it involves latent heat of evaporation
Melting
Bond breaking as it requires energy
Meanwhile bond forming is exothermic as it release energy
