The process in which water vapour and carbon dioxide
traps heat is called the “greenhouse effect”.
The greenhouse effect is a natural phenomenon which
occurs every day. To illustrate an example of this natural phenomenon, d<span>uring the day the Sun shines through the atmosphere.
Earth's surface warms up because of the sunlight. Meanwhile at night in the
absence of the sunlight, Earth's surface cools back and releasing the heat back
into the air. However some of the heat is retained by the greenhouse gases
(such as carbon dioxide and water vapour) in the atmosphere. This process what
keeps our planet Earth warm and cozy at an average temperature of 16°C.</span>

<span>greenhouse effect</span>
When water evaporates of your body it cools you down, hence why after a shower when the water droplets begin to evaporate you feel cold
<span>An imaginary line perpendicular to a reflecting surface is called "a normal" (principle line)
So, Your Answer would be Option B

Yes, that's correct. That's a big part of the reason why
the soap floats in water and the sponge sinks in it.
Answer is given below
Explanation:
given data
pressure = double
volume = constant
solution
As we know that an Average velocity and rms velocity is directly proportional to square root of PV ..................1
so if we take P is doubled while keeping V constant
than Velocity increases by a factor 
so that Factor = 1.414 for both the cases
