MASTER SET,BOMI ENERGY MANAGEMENT
AND CONTROLS QUESTIONS WITH VERIFIED
ANSWERS 2025
Define Thermal Energy-correct-answer-Energy associated with the movement of
molecules and measured as heat
Define Electrical Energy-correct-answer-Energy associated with the flow of
negatively charged electrons through a conductive medium.
Define Mechanical Energy-correct-answer-The sum of kinetic and potential
energy. Kinetic being the energy of motion, potential being stored energy.
Define BTU-correct-answer-Quantity of heat possessed by an object is measured
in BTU. It is the amount of heat required to raise temp of one pound of pure water
one degree F at sea level.
What is the fundamental law of heat transfer?-correct-answer-heat always flows
from an object that is warmer to an object that is cooler.

What are the three factors affecting amount and rate of heat flow through a
building envelope?-correct-answer-1. Total surface area
2. Temperature differences
3. Material properties.
What are the four factors uses to evaluate the materials that form a building
enevlope?-correct-answer-1. Thermal Conductivity
2. Thermal Conductance
3. Thermal Resistance
4. Overall Coefficient of heat transfer
What is thermal conductivity?-correct-answer-The measurement of a materials
ability to conduct heat.
What is thermal conductance?-correct-answer-A measure of the rate of heat flow
through a material or air space.
What is thermal resistance?-correct-answer-A materials ability to retard heat
flow.
,3|Page
What is the overall coefficient of heat transfer?-correct-answer-Resistance value
of all building materials, air spaces, including walls, ceilings and surface air films.
What happens when heat is added to a substance?-correct-answer-It's molecular
motion increases.
What is temperature?-correct-answer-The measurement of the intensity of heat.
What does a BTU measure?-correct-answer-The quantity of heat.
What is sensible heat?-correct-answer-heat that when added to or removed from
a substance it changes the temperature of the substance
What is specific heat?-correct-answer-The ratio of the temperature it takes to
raise the temperature of a substance 1 degree to the amount of heat it takes to
raise a pound of pure water 1 degree.

What is the formula for determining the amount of heat required to change the
temperature of a substance without changing the substances state?-correct-
answer-Heat required in BTU - weight in LB X specific heat X temp change in
degrees F.
What is latent heat?-correct-answer-Heat that when added or removed from a
substance changes that substances state, but not its temperature.
What are the standard terms used to describe the change of a substance from one
state to another through the absorption or release of latent heat?-correct-
answer-solid to liquid: melting
liquid to solid: fusion
liquid to gas: vaporization
gas to liquid: condensation
What are the three basic processes of heat transfer?-correct-answer-Conduction,
Convection, Radiation
What is conduction?-correct-answer-Heat transfer through matter, molecule to
molecule, due to temp difference
