Question

Q29 Arrange the following in increasing order of their Global warming potential,

1. Carbon di oxide

2. Methane

3. Nitrous oxide

• A. a) 1<2<3
• B. b) 3<2<1
• C. c) 2<3<1
• D. d) 2<1<3

Answer 1

The correct option is A

a) 1<2<3

29 Ans A

Explanation: Global warming potential (GWP) is a relative measure of how much heat a greenhouse gas traps in the atmosphere. It compares the amount of heat trapped by a certain mass of the gas in question to the amount of heat trapped by a similar mass of carbon dioxide. A GWP is calculated over a specific time interval, commonly 20, 100 or 500 years. GWP is expressed as a factor of carbon dioxide (whose GWP is standardized to 1)
