Answer:

p1/T1=p2/T2

760mmHg/212°F=731mmHg/T2

T2= 203.91°F

760mmHg/100°C=731mmHg/T2

T2= 96.18°C

Explanation:

You'd have to choose in which units you want to express the temperature.

In the so called rain shadow effect we have interaction between all of the four major Earth spheres. When we have a coastal region where there's a high mountain range, the part of the mountain that is facing the sea will differ a lot from the part of the mountain that is on the other side. The water from the sea evaporates. The water vapor makes the air wet. The warm and wet air masses from the sea will come to the coastline, once they reach the mountain they will start to accumulate as they can not pass through it. As they accumulate rainfall appears. The rainfall contributes to a lush vegetation on this side of the mountain (windward side). The rain shadow effect appears on the leeward side of the mountain, and it mostly gets dry, strong, downward winds. These conditions result in drier climate, much less vegetation, and much increased erosion. Thus we can easily see that we have in this case interaction between the hydrosphere (the sea and the rainfall), the geosphere (the ground, soil, rocks), biosphere (the vegetation), and atmosphere (the winds, the clouds).

(b) Ozone absorbs radiation of wavelengths 2200–2900 Å, thus protecting organisms from this radiation. Find the frequency and en
GrogVix [38]

The frequency and energy of most energetic of these photons is1.36*10^{15} Hz and 9.04*10^{-19} J respectively.

The high energy photons will have least wavelength. Taking the given less wavelength for calculation of frequency and energy of photons.

λ = 2200  Å

Also, we know, 1 Å = 10^{-10} m

So, λ = 2200*10^{-10}

λ = 2.2*10^{-7}<em> </em>m

Now, calculating frequency using the formula -

c = fλ, where c is speed of light, f is frequency and λ is wavelength.

We know, c = 3*10^{8} m/s

f = c/λ

f = \frac{3*10^{8} }{2.2*10^{-7} }

frequency = 1.36*10^{15} Hz

Now, calculating Energy through the formula -

E = hf, where E is energy, h is planck's constant and f is frequency

Value of planck's constant = 6.63*10^{-34} Js

E = 6.63*10^{-34}*1.36*10^{15}

Energy = 9.04*10^{-19} J

Thus, frequency and energy of photons is 1.36*10^{15} Hz and 9.04*10^{-19} J respectively.

Calculate the number of copper atoms in a penny.
Grace [21]
Since a mole of atoms contains 6.0221 x 1023 atoms, there are 2.2452 x 1022 zinc atoms and 5.9230 x 1020 copper atoms in a penny, for a total of 2.3044 x 1022 atoms in a penny. Public Domain Image, source: NASA/JPL-Caltech
