Answer:
A space station
Explanation:
A space station provides an avenue for scientist to orbit the space and carryout scientific findings. Most space stations are usually controlled under agreement between different countries. The international space station is one such example.
A rover is usually a robotic device that has been pre-programmed and equipped with state of the art devices to carryout explorations on their own.
Most space observations are usually powerful telescopes on the earth surface that monitors events in space.
A satellite is a body that orbits another.
Answer:
15.17 g
Explanation:
To answer this, we need to find the molar mass of nickel in nickel (II) fluoride. The formula for nickel (II) fluoride is NiF2. This gives us the molar mass of 96.69 g. The mass percentage of nickel is 60.70% approximately (as we divide the molar mass of nickel by that of nickel (II) fluoride), and 60% of 25g gives us 15.17 g
Answer:
I think the answer is distillation
Explanation:
The amount of moisture present in air at a given temperature is known as humidity.
Whereas relative humidity is the amount of percentage of moisture it contains when compared to the maximum moisture it can contain at a given temperature.
Also % Relative humidity (RH) = 
where, P = the partial pressure of water vapour
= the equilibrium vapor pressure at a particular temperature.
Accrding to the Clausius-Clapeyron equation, decreases with decrease in temperature.
Hence, it means that at super-cooled conditions the %RH would be 100%.
On the other hand, the temperature will be very high at super-heated conditions.
Hence, will be high hence %RH will be low.
It is also known that at saturated condition, P =
Therefore, %RH is 100.
Thus, we can conclude that when the relative humidity is 90%, we say the air is humid.
