Answer:
Explanation:
By Ideal Gas Law, P1*V1 / T1 = P2*V2 / T2
So new pressure = (P1*V1 / T1) / (V2 / T2)
= P1*V1*T2 / T1*V2
= 800*3.6*298 / 250*1.8
= 1907.2 mmHg
I think it is D

Answer:
Choice B., infrared radiation
Explanation:
A gas in atmosphere which allows the incoming of the solar radiation to reach Earth's surface and on the other hand also absorbs these radiation which are re-emitted as heat, trapping heat in atmosphere and causing temperature to rise is called green house effect.
<u>For example, carbon dioxide is a greenhouse gas which traps heat from sun resulting in the warming the planet
.</u>
<u>Thus, infrared radiations which is a source of heat is reflected back to the Earth’s surface by greenhouse gases.</u>
