Thermodynamic Part 2
Law of Heat Exchange
This law states that the heat given up by a hotter body is equal to the heat absorbed by a colder body.
heat gained
the heat lost is equal to the ?
Zeroth Law
It states that if two systems are in thermodynamic equilibrium with a third system, the two original systems are in thermal equilibrium with each other.
First Law
states that energy can be converted from one form to another with the interaction of heat, work and internal energy, but it cannot be created nor destroyed, under any circumstances.
Second Law
states that the state of entropy of the entire universe, as an isolated system, will always increase over time
Entropy
measure of the disorder of a system or energy unavailable to do work
Third Law
states that the system’s entropy approaches a constant value as its temperature approaches absolute zero
Latent Heat
When substances change in phase (e.g. Solid to Liquid), there exists an associated heat requirement that does not show as change in temperature. The nature of this heat requirement is called ?
Latent Heat
the basis for constant associated with the heat required to change the phase of a
material.
Condensation
Gas to Liquid
Deposition
Gas to Solid
Sublimation
Solid to Gas
Melting or Fusion
Solid to Liquid
Vaporization
Liquid to Gas
freezing
Liquid to Solid
Latent Heat of Fusion
It is the quantity of heat needed to change solid state to liquid state.
Latent Heat of Vaporization
It is the quantity of heat needed to change liquid state to gas state.
