Thermodynamics

The 1st law of Thermodynamics

• Energy can not be created or destroyed. It just changes forms.

• Energy can only be created by the sun

• Some energy is lost to the environment.

2nd law of thermodynamics

• Every time energy changes form, some of it is lost to the environment

• Energy can't be created or destroyed

• All energy generates heat

Conductor

• A material that thermal energy travels through easily

• A material that energy does NOT transfer through easily

• Energy that travels in the form of electromagnetic waves

Heat transferred by direct contact is:

• Conduction

• Convention

• Radiation

• illegal because quarantine

Heat transferred by currents in a liquid or gas is:

• Conduction

• Convention

• Radiation

• Icky

Heat will never flow from a cold object to a hot object on its own describes which law of thermodynamics?

• 1st Law of thermodynamics

• 2nd Law of thermodynamics

• 3rd Law of thermodynamics

• 4th Law of thermodynamics

Entropy is a measure of:

• order
• disorder

When thermal energy is added to a substance, the substance's particles move:

• More rapidly at an increased diestance from each other.
• More rapidly with less distance between each other.
• More slowly with a greater distance between each other.
• More slowly with a reduced distance between each other.

The kind of heat transfer that travels through space in electromagnetic waves is ______________________.

• insulation.
• Radiation
• Conduction
• Convection

How does heat move to melt ice?

• from the ice to the water
• from the water to the ice
• from the water to the air
• from the air to the water
