26
Q

3 Types of Van der Waals Forces

A

1) dipole-dipole
2) dipole-induced dipole
3) dispersion

27
Q

29
Q

A temporary dipole forms in a non- polar molecule which leads to a temporary dipole to form in ANOTHER non-polar molecule.

36
Q

At constant volume, the pressure of a fixed gas is directly proportional to the absolute temperature.

A

Gay Lussacs Law

37
Q

A

Combined Gas Law

38

Q

Ideal Gas Law formula

A

PV=nRT

A

The law of conservation of energy

44
Q

The second law of thermodynamics states that the total entropy of a system either increases or remains constant in any spontaneous process; it never decreases.

A

Law of Entropy

45
Q

It states that if two bodies are each in thermal equilibrium with some third body, then they are also in equilibrium with each other
