Question

Can someone please check my answers??

Which of the following conditions occurs as a liquid freezes?
(Points : 1)
Kinetic energy of the liquid molecules exceeds the strength of the intermolecular forces.

Kinetic energy of the liquid molecules equals the strength of the intermolecular forces.

Strengths of intermolecular forces of the liquid molecules exceed the kinetic energy of the molecules.
****** my answer is D

Answer 1

Two pots are at the same atmospheric pressure, but one has a lid on it. The pressure above the liquid in pot A is 115 kPa, while the pressure above pot B is 102 kPa. Which pot will boil at a higher temperature?
(Points : 1)
Pot A will boil at a higher temperature.

Pot B will boil at a higher temperature.

Both pots boil at the same temperature.

The pressure has no effect on boiling point.
*****my answer is A

Answer 2

The molecular masses of four substances are as follows: A = 16, B = 58, C = 86, D = 116. Which substance will have the lowest boiling point?
(Points : 1)
A

B

C

D
*******my answer is A

Answer 3

In terms of intermolecular forces, explain why atoms and molecules in a liquid move in random patterns.
(Points : 1)
vibration alone

very little molecular motion at all

rapid random movement in straight lines alone

vibration and some linear motion like sliding around
*******my answer is D

Answer 4

Which factor does not influence whether a substance will be a liquid at room temperature and normal atmospheric pressure?
(Points : 1)
strength of intermolecular forces

molecular shape

surface tension

molecular mass
********my answer is C

Answer 5

Never mind i got them all right
