1. Which of the following gases is primarily responsible for the
greenhouse effect?
A. Nitrogen
B. Oxygen
C. Carbon dioxide
D. Argon
Answer: c) Carbon dioxide
Rationale: Carbon dioxide (CO2) is the main greenhouse gas
contributing to global warming and climate change by trapping heat in
the Earth's atmosphere.
2. What is the primary purpose of energy management in a business or
organization?
A. To increase energy consumption
B. To reduce energy costs and improve efficiency
C. To increase energy production
D. To replace all energy equipment with new technology
Answer: b) To reduce energy costs and improve efficiency
Rationale: Energy management focuses on optimizing energy use,
reducing waste, and lowering costs, which leads to greater operational
efficiency.
,3. What is the energy transformation that occurs in a nuclear power
plant?
A. Chemical energy to electrical energy
B. Nuclear energy to electrical energy
C. Kinetic energy to electrical energy
D. Solar energy to electrical energy
Answer: b) Nuclear energy to electrical energy
Rationale: In a nuclear power plant, nuclear energy (from the splitting
of atoms) is converted into heat, which is then used to produce
electricity.
4. Which energy source has the least environmental impact?
A. Coal
B. Natural gas
C. Solar energy
D. Nuclear energy
Answer: c) Solar energy
Rationale: Solar energy has the least environmental impact, as it
produces no greenhouse gases or pollutants during operation and is
renewable.
, 5. Which of the following is the most common form of renewable
energy used in electricity generation?
A. Wind
B. Coal
C. Natural gas
D. Nuclear
Answer: a) Wind
Rationale: Wind energy is one of the most common forms of renewable
energy globally used to generate electricity. It is a clean and
sustainable energy source.
6. How can heat loss from a building be minimized?
A. By opening windows regularly
B. By installing double-glazed windows
C. By increasing the internal temperature
D. By using more electrical appliances
Answer: b) By installing double-glazed windows
Rationale: Double-glazed windows have an insulating layer of air
between two panes of glass, reducing heat loss and improving energy
efficiency.
