100

This is the scientific principal that states that energy can neither be created nor destroyed by ordinary physical means.

What is the Law of Conservation of Energy?

100
This is name for the only temperature that all phases of matter can exist.

What is room temperature or 70 degrees F.

100

This is how heat is different from thermal energy.

What is heat is the flow of energy from one place to another and the thermal energy is the form of energy associated with the particle motion and position?

100

Transportation, aerospace, electronics, and manufacturing.

What are trades that use chemicals in gas form?

100

These are the four variables in the Ideal Gas Law.

What is volume (V), Pressure (P), Temperature (T), Moles (n)?

200

This is a temperature scale that has an absolute zero, below which temperatures do not exist.

What is Kelvin temperature scale?

200

This metal is liquid at room temperature.

What is mercury?

200

This is when molecular energy is at a minimum.

What is absolute zero?

200

This is standard temperature and pressure (STP).

What is 1 atm and 273 K?

200

6.0221X1023 molecules

What is 1 mole?

300

This is the measure of the average of kinetic energy of particles in an object due to their range of motions.

What is temperature?

300

This group of elements exist as gases at room temperature.

What are noble gases?

300

This is what thermal energy is changing into when ice melts.

What is potential energy?

300

These are the conditions which gases respond to.

What are temperature, pressure, volume, and amount?

300

PV=nRT=NkT

What is the formula for the Ideal Gas Law?

400

This means light energy.

What is radiation?

400

This is when molecules have the highest level of kinetic energy.

What is gas state?

400

This is used to describe the behavior of gas.

What is Kinetic Molecular Theory?

400

This is a hypothesis that state that the number of molecules of gas in a certain constant volume is the same for any gas as long as the pressure and temperature remain constant.

What is Avogadro's Hypothesis?

400

The letter N in an equation represents this.

What is molecules?

500

This is force per unit area.

What is pressure?

500

When liquid water loses kinetic energy, this happens.

What is freezing?

500
This occurs when water vapor loses kinetic energy.

What is condensation?

500

In gas, these are directly proportional at constant pressure.

What are temperature (in Kelvins) and volume?

500

This is when two variables move in opposite directions in the same proportion.

What is inversely proportional?
