Heating of an organic substance without an external heat source is known as:
- A.
Spontaneous heating
- B.
Heat of decomposition
- C.
Dielectric heating
- D.
Frictional heat
Correct Answer
A. Spontaneous heatingExplanation
Spontaneous heating refers to the process of heating an organic substance without the need for an external heat source. This phenomenon occurs due to the exothermic reactions that take place within the substance itself, leading to an increase in temperature. Unlike other forms of heating mentioned, such as heat of decomposition (which involves the breakdown of a substance) or dielectric heating (which uses an electric field), spontaneous heating occurs naturally and does not require any additional energy input. Frictional heat, on the other hand, involves the generation of heat through mechanical friction, which is not applicable in this context.Rate this question:

The release of heat usually due to bacterial action BEST defines:
- A.
Spontaneous heating
- B.
Heat of decomposition
- C.
Heat of compression
- D.
Heat of solution
Correct Answer
B. Heat of decompositionExplanation
Heat of decomposition refers to the release of heat that occurs when a substance breaks down or decomposes into simpler compounds or elements. This process is often caused by chemical reactions or the action of bacteria. Bacterial action can lead to the breakdown of organic matter, resulting in the release of heat as a byproduct. Therefore, heat of decomposition is the most appropriate term to define the release of heat due to bacterial action.Rate this question:

In order to have spontaneous heating, the substance must be:
- A.
Insulated
- B.
Organic
- C.
Inorganic
- D.
Explosed to sunlight
Correct Answer
B. OrganicExplanation
Spontaneous heating refers to the process where a substance undergoes combustion without an external ignition source. Organic substances, such as fuels, are more prone to spontaneous heating compared to inorganic substances. This is because organic substances contain carbon and hydrogen, which can react with oxygen in the air to release heat energy. Inorganic substances, on the other hand, do not typically have the necessary chemical properties to undergo spontaneous combustion. Therefore, the correct answer is organic.Rate this question:

The phenomenon by which heat, smoke, and fire gases will travel upward to the highest point and become trapped, bank down, and spread out laterally is known as:
- A.
Back draft
- B.
Thermal layering
- C.
Flashover
- D.
Buoyancy
Correct Answer
B. Thermal layeringExplanation
Thermal layering refers to the phenomenon where heat, smoke, and fire gases rise upwards due to their lower density compared to the surrounding air. As they reach the highest point, they become trapped and spread out laterally. This process is a result of buoyancy, as the hot gases are lighter and tend to rise. It is important to understand thermal layering in firefighting to effectively control and extinguish fires.Rate this question:

In tall buildings, layering on top floors may be delayed until there is:
- A.
Sufficient heat build up to cause the upward movement of smoke and fire gases
- B.
Admission of sufficient oxygen to cause flashover
- C.
An adequate roof opening to discharge smoke and fire gases
- D.
Enough water applied to cool the gases as they are leaving the seat of the fire
Correct Answer
A. Sufficient heat build up to cause the upward movement of smoke and fire gasesExplanation
In tall buildings, layering on top floors may be delayed until there is sufficient heat build up to cause the upward movement of smoke and fire gases. This means that the fire needs to generate enough heat to create an upward draft, which will allow the smoke and fire gases to rise and create a layering effect. Without sufficient heat build up, the smoke and fire gases may not rise and spread throughout the building, delaying the layering process.Rate this question:

Heat that results from the effects of either high frequency alternating current on a nonconductor or pulsating direct current best defines ______ heating.
- A.
Resistance
- B.
Dielectric
- C.
Induction
- D.
Static electricity
Correct Answer
B. DielectricExplanation
Dielectric heating refers to the process of generating heat in a nonconductor, such as a dielectric material, when exposed to high frequency alternating current or pulsating direct current. Dielectric heating occurs due to the phenomenon of molecular polarization, where the molecules in the dielectric material align with the alternating electric field and generate heat as they continuously reorient themselves. This heating mechanism is commonly used in applications such as microwave ovens and radio frequency heating.Rate this question:
