Comprehensive Test Review (Qns & Ans)
2025
1. Which of the following parameters is directly measured by a
thermo-hygrometer?
- A) Air velocity and pressure
- B) Temperature and humidity
- C) Moisture content in materials
- D) Thermal conductivity
- ANS: B) Temperature and humidity
- Rationale: A thermo-hygrometer is used to measure both
temperature and humidity of the air, providing important data for
assessing environmental conditions.

,2. What is the primary use of a moisture meter in building
inspections?
- A) To measure ambient air temperature
- B) To detect water leaks in plumbing systems
- C) To measure the moisture content in building materials
- D) To measure air pressure differences
- ANS: C) To measure the moisture content in building
materials
- Rationale: Moisture meters are used to measure the
moisture content in various building materials, which is crucial
for identifying potential areas of water damage and mold growth.
3. Which principle of thermodynamics states that energy cannot
be created or destroyed, only transferred or transformed?
- A) Zeroth Law of Thermodynamics
- B) First Law of Thermodynamics
- C) Second Law of Thermodynamics
- D) Third Law of Thermodynamics
- ANS: B) First Law of Thermodynamics
- Rationale: The First Law of Thermodynamics, also known
as the Law of Energy Conservation, states that energy cannot be
created or destroyed, only transferred or transformed.

4. The __________ is the device used to visually inspect the
temperature distribution of surfaces using infrared radiation.
- ANS: Thermal imaging camera
- Rationale: A thermal imaging camera is used to detect and
visualize temperature distribution on surfaces, which is valuable
for identifying areas of heat loss, insulation issues, and moisture
intrusion.
5. In psychrometry, the __________ temperature is the
temperature at which air becomes saturated with moisture and
condensation begins to occur.
- ANS: Dew point
- Rationale: The dew point temperature is the temperature at
which air becomes fully saturated with moisture and water vapor
begins to condense into liquid.
6. The __________ principle explains the relationship between
pressure, volume, and temperature in a gas, stating that the
product of pressure and volume is directly proportional to
temperature.
- ANS: Ideal Gas Law
- Rationale: The Ideal Gas Law explains the relationship
between pressure, volume, and temperature in a gas, represented
by the equation PV = nRT.
