ARSON UNA

Question 1

refers to the natural condition created by the fire or the normal movement of fire, smoke and fire gases within a structure or building.

Answer 1

Thermal balance

Question 2

refers to those turbulent circulations of steam and smoke which-replaces the normal flow of the products of combustion. Hot spots may develop during the extinguishment of the fire upsetting the thermal balance; such holes produced may mislead the investigator to believe that the fire originated at that
location.

Answer 2

Thermal Imbalance

Question 3

there are four known sources of heat, namely:

Answer 3

CHEMICAL
ELECTRICAL
NUCLEAR
MECHANICAL

Question 4

. refers to the amount of heat absorbed by a substance when a substance from solid to a liquid, and from a liquid to gas. On the other hand, heat is released during the conversion of a gas toliquid orliquid to solid.

Answer 4

LATENT HEAT

Question 5

is the quantity of heat necessary to convert solid to liquid.

Answer 5

HEAT OF FUSION

Question 6

is the quantity of heat absorbed when a substance is converted from liquid to gas.

Answer 6

HEAT OF VAPORIZATION

Question 7

• refers to the manner in which fuel ignites, flame develops and fire spreads.

Answer 7

FIRE BEHAVIOUR

Question 8

on the other hand it is the abnormal movement of fire due to interference of foreign matter.

Answer 8

THERMAL IMBALANCE

Question 9

Heat is the flow of energy from a high temperature to a low temperature.
When these temperatures balance out, heat stops flowing, then the system (or set of systems) is said to be in

Answer 9

Thermal Equilibrium

Question 10

is a process by which energy in the form of heat is exchanged between bodies or parts of the same body at different temperatures.

Answer 10

Heat Transfer

Question 11

Which refers to the passage of heat energy from particles to particles contact of in a substance.

Answer 11

CONDUCTION

Question 12

Materials that allow thermal energy to readily flow through them.

Answer 12

CONDUCTORS

Question 13

• Usually generated by intense fire it refers to heat travel in an upward movement.

Answer 13

CONVECTION

Question 14

Heat transfered even when separated to a vacuum. It iscommonly applied to all kinds of electromagnetic-wave phenomena, The process in which energy such as heat and rgys of light is sent out from atoms and molecules as they undergo internal alteration. This energy travels in a straight line with the speed of light.

Answer 14

Radiation

Question 15

Materials that resist the flow of heat

Answer 15

INSULATORS

Question 16

Transfer of energy by the rising or sinking of matter due to density differences.

Answer 16

CONVECTION

Question 17

it consists of a tube filled partially with líguid that measures the expansion
and contraction of the/liquid with changes on temperature. The Tube is calibrated to allow the reading of the level of the liquid in degrees of a temperaturescale.

Answer 17

thermometer
