Kinetic Theory of Gases:
Assumptions in Kinetic theory
- Gas atoms and molecules spend more of their time moving freely, they move
with a constant speed in a straight line path.
* Collisions with other atoms and molecules in the gas are infr
The avogadro number is Na= 6.02 X10^23
- It is the number of molecules (or atoms) in a mole.
The molar atomic mass number (molecular mass for molecules) of an element is the
mass of a sample of the element contains one mol
The bar is placed between two separate systems at different temperatures
The bar conducts heat :energy flows from the hot end to the cold end of the bar
Heat conduction is through transfer of vibrational energy from hot atom
Phases of matter
There are three states of matter shown:
- Solid, Liquid, Gas
The transformation of a solid to a liquid, a liquid to a gas, and vice versa is called a
Phase changes can be produced by changing the temperature
Thermodynamics is about the transfer of energy between the systems of particles.
Thermodynamics focuses on energy ranther than forces
Conservation of energy is a key pillar of thermodynamics
It is also about the way changes in the energy of a
