Answer:
Explanation:
Hello,
By applying the Dalton's law, we can compute the partial pressure of the helium has:
Now, solving for the partial pressure of the helium gas we get:
On the other hand, the mass of the helium gas is computed via the ideal gas equation in terms of the helium's mass:
Best regards.
Answer:
o Surface Type- Because the atmosphere is heated by the Earth's surface, the surface type plays an important role in the surface air temperature. o Elevation and Aspect- Higher altitude generally has colder temps b/c the air is less dense and there are fewer molecules to absorb incoming solar radiation.
The Earth's surface is actually what heats the air above it.
Explanation:
The energy from the sun is "short-wave", and as such air is transparent to it. The sunlight goes right through the air without heating it at all. This "short-wave" radiation is absorbed by the Earth which then heats up. The heated Earth then emits it's own radiation but it is in the infrared part of the spectrum or "long-wave" radiation. This heat is what warms the atmosphere.

to remove iodine sublime
to remove sand filter
to remove water evaporate
Explanation:
1. put the mixture in a beaker
2.Heat the mixture using a watch glass filled with cold water, the iodine will sublime at the base of the watch glass.
3.Add water to sand and salt. Stir for salt to diffuse in the water
4.Filter sand from the solution using a filter paper
5.evaporate the remaining water to remain with Salt crystals.
