Heat

What is heat?
Heat is the form of energy that can move from a hotter to cooler place.

What is Thermal equilibrium?
In My Own Words,
Thermal equilibrium is equal temperature between two objects.
Heat travels from a hotter to cooler object.
When Thermal Equilibrium occurs,
The temperature of the cooler object rises.
The temperature of the hotter object falls.
This carries on until it reaches equal temperature. This is Thermal Equilibrium...

Extra questions:

What is Static equilibrium?
The special case of mechanical equilibrium of a stationary object is static equilibrium. For example, a paperweight on a desk would be in static equilibrium...

What is Dynamic Equilibrium?
Dynamic Equilibrium has a lot of definetions.
1. A condition in which all acting influences are canceled by others, resulting in a stable, balanced, or unchanging system.
2. Mental or emotional balance; poise.
3. Physics. The state of a body or physical system at rest or in unaccelerated motion in which the resultant of all forces acting on it is zero and the sum of all torques about any axis is zero.
4. Chemistry. The state of a chemical reaction in which its forward and reverse reactions occur at equal rates so that the concentration of the reactants and products does not change with time.

What is Convection, Conduction and Radiation

Conduction is the movement of heat through a material without obvious movement of the material itself. (Usually occurs in solids)
Convection is the movement of heat through a material by the movement of itself.(Usually occurs in liquids)
Radiation is the transfer of heat energy through empty space. (Radiation is the only thing that can occur in Vacuums)

Land Breeze and Sea Breeze...When does it occur?
Land Breeze occurs in the Night while Sea Breeze occurs in the Day.

It is all due to conduction and convection. In the day, Sea Breeze occurs. The sea cools faster than the land. The sea is warmed by the sun to a greater depth than the land. The sea therefore has a greater capacity for absorbing heat than the land, so the surface of the sea warms up more slowly than the land's surface.

As the temperature of the land rises, the land heats the air above it. The warm air is less dense and so it rises. This rising air over the land lowers the sea level pressure. The cooler air above the sea, flows towards the land, creating a cooler breeze near the coast. This cycle repeats again.
Land Breeze, which occurs in the night, is the opposite
A: Sea Breeze
B: Land Breeze
