The quantity of thermal energy that is transferred.

1 PT heat

According to the 2 nd law of thermodynamics, it’s how heat flows

2 PT From the hotter object to the colder object

It’s what occurs when heat stops flowing

3 PT Thermal equilibrium (when both objects are the same temperature)

It’s the sum of the KE and PE of the particles that compose matter.

4 PT Thermal energy

It’s the amount of thermal energy required to raise the temperature of 1kg of a substance by 1 degree C.

5 PT Specific heat capacity

According to the kinetic theory, it is why the temperature of a substance increases.

1 PT The particles that make up the substance vibrate faster.

It’s the measure of the average kinetic energy of the particles of a substance.

2 PT temperature

It’s why the fluid in a thermometer rises.

3 PT The fluid expands as it increases in temperature

The quantity of heat either gained or released that causes a phase change from a solid to a liquid or liquid to a solid.

4 PT Latent Heat of Fusion

It’s why evaporation cools your skin.

5 PT Heat is absorbed from your sweat when water molecules evaporate, leaving the sweat cooler and your skin cooler.

A substance that is able to store a large quantity of heat has this type of specific heat capacity

1 PT High Specific Heat Capacity

Its why a bimetallic strip bends in a flame

2 PT One metal expands farther than the other, causing it to bend towards the metal that expands less.

The intensity of sunlight decreases as this angle decreases

3 PT The insolation angle

Heat engines transfer these two forms of energy, one to the other

4 PT Thermal energy to mechanical energy.

What must be absorbed when a substance goes from solid to liquid to gas and from where does it come?

5 PT Thermal energy from the surroundings

It’s the three ways that thermal energy is transferred.

1 PT Convection, conduction and radiation

This thermal energy transfer process does so by direct contact of two materials with different temperatures.

2 PT Conduction.

This thermal energy transfer process occurs when hot, less dense fluids rise and cooler, more dense fluids sink.

3 PT Convection.

This thermal energy transfer process occurs by electromagentic waves

4 PT Radiation.

It’s what allows hot fluids to rise

5 PT A decrease in density in a substance compared to the surroundings due to expansion

These materials transfer heat rapidly.

1 PT Conductors

These materials reduce unwanted transfers of thermal energy.

2 PT Insulators

It’s the type of heating system that uses air, ductwork and vents

3 PT Forced air heating system

It’s the basic 4-step function of any heating system

4 PT Burn a fuel, heat a fluid, circulate the heated fluid, transfer heat

This word means the measure of disorder in a system.

5 PT Entropy.
