Answer:
Explanation:
Given:
volume of air in the room, 
temperature of the room, 
<u>Saturation water vapor pressure at any temperature T K is given as:</u>
<u />
<u />
putting T=298 K we have
<u>The no. of moles of water molecules that this volume of air can hold is:</u>
Using Ideal gas law,
is the maximum capacity of the given volume of air to hold the moisture.
Currently we have 80% of n, so the mass of 20% of n:
where;
M= molecular mass of water
is the mass of water that can vaporize further.
40
Because if you divide 3,600 by 90 it is equivalent to 40.
Hope this helps, have a blessed day :)
Angel ! You have a formula, and you have an example that's
completely worked out. The ONLY POSSIBLE reason that you
could still need help is that you're letting math scare you.
I'll do 'A' for you, 'B' most of the way, and get 'C' set up.
If THAT's not enough for you to run with and finish them all,
then you and I should both be embarrassed.
Write the formula on the wall:
°F = (9/5) °C + 32°
A). Convert 35° C °F = (9/5)(35°) + 32°
(9/5)(35) = 63 °F = 63° + 32°
°F = 95°
____________________________________
B). Convert 80°F to °C
The formula: °F = (9/5) °C + 32°
°F = 80 80 = (9/5)°C + 32
Subtract 32 from each side: 48 = (9/5)°C
Multiply each side by 5 : 240 = (9) C
Now you take over:

C). Convert 15°C to °F.
The formula: °F = (9/5) °C + 32°
°C = 15 °F = (9/5) 15° + 32
(9/5) (15) = 27
Go ! °F =
Answer:
critical angle = 64.79°
ray will not penetrate into the water
Explanation:
given details
refractive index of oil n1 = 1.47
refractive index of water n2= 1.33
incident angle = 71.4 °
= sin^{-1}(\frac{1.33}{1.47}
critical angle = 64.79°
incident angle > critical angle = reflection
incident angle < critical angle = refraction
In this case, 71.4 > 64.79 therefore it will undergo total internal reflection
therefore ray will not penetrate into the water
