CDI 4 Q.2

Is a measure of the degree of molecular activity of a material compared to a reference point.

• Heat energy

• Temperature

• Heat release rate

• Heat flux

The following is the normal body temperature, except:

 

• 100 °F

• 37 °C

• 98.6 °F

• 310.15 K

Human skin receives a first degree burn.

    

• 48 °C

• 118 °F

• 321.15 K

• All of the above

Also known as power or the rate at which fire releases energy.

• Heat energy

• Temperature

• Heat release rate

• Heat flux

The rate of energy transferred per surface unit area.

• Heat energy

• Temperature

• Heat release rate

• Heat flux

It is the old and new ways of visualizing the combustion process, the fire triangle and fire tetrahedron.

• Fire triangle theory

• Fire theory

• Fire tetrahedron theory

• Fire extinguishment theory

This theory states that fire is created with the presence of oxygen, heat and fuel.

• Fire triangle theory

• Fire tetrahedron theory

• Fire theory

• Fire extinguishment theory

Under this theory, another component of fire was added which is the uninhibited chemical chain reaction which will enable fire to start with the presence of the three elements of fire, the oxygen, heat and fuel.

• Fire triangle theory

• Fire tetrahedron theory

• Fire theory

• Fire extinguishment theory

It is the energy sufficient to release vapor from the fuel and cause ignition.

• Oxygen

• Heat

• Fuel

• Uninhibited chemical reaction

Serves as an oxidizing agent that oxidizes the fuel.

• Oxygen

• Heat

• Fuel

• Uninhibited chemical reaction
