Reference for Global Warming Potential
Question & Answer (English)
Global Warming Potential (GWP) is measured relative to which gas?
- Methane (GWP = 1)
- Carbon Dioxide (GWP = 1) — Correct Answer
- CFCs (GWP = 1)
- Water Vapor (GWP = 1)
Correct Answer Explanation
Global Warming Potential (GWP) is a measure of how much heat a greenhouse gas traps in the atmosphere relative to Carbon Dioxide ($CO_2$). Therefore, $CO_2$ is assigned a reference GWP value of 1.
Incorrect Options Analysis
- Methane: Has a GWP of roughly 28-30 times that of $CO_2$ over 100 years.
- CFCs/SF6: Have extremely high GWP values (thousands of times higher than $CO_2$).
प्रश्न एवं उत्तर (हिंदी)
ग्लोबल वार्मिंग पोटेंशियल (GWP) किसके सापेक्ष मापा जाता है?
- मीथेन (GWP = 1)
- कार्बन डाइऑक्साइड (GWP = 1) — सही उत्तर
- CFCs (GWP = 1)
- जल वाष्प (GWP = 1)
सही उत्तर स्पष्टीकरण
ग्लोबल वार्मिंग पोटेंशियल (GWP) यह मापता है कि कोई गैस कार्बन डाइऑक्साइड ($CO_2$) की तुलना में कितनी ऊष्मा (heat) को रोकती है। इसलिए, $CO_2$ का मान संदर्भ के रूप में 1 माना जाता है।
गलत विकल्पों का विश्लेषण
- मीथेन: इसका GWP $CO_2$ से लगभग 28-30 गुना अधिक होता है।
- CFCs: इनका GWP $CO_2$ की तुलना में हजारों गुना अधिक होता है।
