Hotel Service Unit 9 Q1 Quiz

Correct Answer:
B) By combusting fuels that contain sulfur, which reacts with oxygen during the combustion process

Explanation:
Sulfur oxides (SOₓ) are produced when sulfur-containing fuels are burned. During combustion, sulfur in the fuel reacts with oxygen in the air, forming sulfur dioxide (SO₂) and other sulfur compounds.

Correct Answer:
A) Emission Control Area

Explanation:
ECA stands for Emission Control Area, a designated area where stricter controls are in place to reduce airborne emissions from ships, including sulfur oxides (SOₓ) and nitrogen oxides (NOₓ), to protect the environment and human health.

Correct Answer:
A) 0.5%

Explanation:
The global sulfur cap set by the International Maritime Organization (IMO) is 0.5% m/m (mass by mass) for marine fuels used outside Emission Control Areas (ECAs) to reduce sulfur emissions.

Correct Answer:
B) Carbon dioxide (CO₂)

Explanation:
Carbon dioxide (CO₂) is the primary pollutant produced when burning hydrocarbon fuels. It is a significant greenhouse gas that contributes to global warming and climate change.

Correct Answer:
A) 0.1%

Explanation:
Within ECAs, the sulfur content in marine diesel oil is limited to a maximum of 0.1% m/m to significantly reduce sulfur oxide emissions and improve air quality in these protected regions.

Correct Answer:
B) They contribute to respiratory issues and exacerbate conditions like asthma

Explanation:
Sulfur oxides (SOₓ) can cause respiratory problems and aggravate pre-existing conditions like asthma. They reduce air quality, particularly in densely populated coastal areas.

Correct Answer:
B) By using energy-efficient engines and switching to cleaner fuels

Explanation:
CO₂ emissions can be reduced by using more energy-efficient engines that consume less fuel and by switching to cleaner fuels, such as low-carbon or renewable fuels, which produce fewer emissions.

Correct Answer:
B) Formation of acid rain, which damages ecosystems and infrastructure

Explanation:
Sulfur oxides (SOₓ) contribute to the formation of acid rain, which can harm aquatic life, soil, forests, and buildings by increasing the acidity of rainwater. This damages ecosystems and erodes infrastructure.
