Review of Combustion: Day 1

Multiple Choice

What are the two molecules are always produced by combustion?

• Heat and light

• It depends on what is being burned

• just carbon dioxide

• carbon dioxide and water

Multiple Choice

Where does the energy being released during a combustion reaction come from?

• Chemical potential energy

• Heat energy

• Thermal energy

• Kinetic energy

Multiple Choice

Energy from combustion heats up surrounding matter in the form of...

• chemical energy

• thermal energy

• What is combustion?

• Water

Temperature, heat, and thermal energy

Multiple Select

The unit most commonly used for energy is the

• Joule

• meter

• liter

• mile

Multiple Select

What two things are used to calculate the kinetic energy of something in motion? Check ALL that apply

• size

• velocity

• mass

• color

Multiple Choice

Temperature is the measure of

• the total amount of kinetic energy a system contains

• the average amount of kinetic energy the system contains.

• how hot something is

• potential energy

Multiple Choice

Thermal energy is....

• Always the same

• Always changing

• the total amount of kinetic energy in a system of molecules.

• the average mount of kinetic energy in a system of molecules

Multiple Choice

Heat is...

• the transfer of thermal energy between systems.

• the same as thermal energy

• energy

Multiple Select

Conduction.... (check ALL that apply)

• Is one type of heat transfer

• Occurs through direct contact

• Transfers kinetic energy between touching objects or molecules

• Is a measure of how hot or cold something is

Multiple Select

Convection .... (check ALL that apply)

• One type of heat transfer

• Occurs through the movement of fluids

• is energy

• Is seen in gasses and liquids

Multiple Choice

Radiation is....

• electromagnetic radiation.

• is always bad for you.

• ...I do not know

Multiple Choice

Electromagnetic energy from combustion...

• is converted to thermal energy when it is absorbed by surrounding matter.

• is the same as thermal energy.

• Is created from nothing before is leaves the fire.

• is the same thing as heat.
