Answer:
Temperature Range:
On average, the surface of the Earth's crust experiences temperatures of about 14°C. However, the hottest temperature ever recorded was 70.7°C (159°F), which was taken in the Lut Desert of Iran as part of a global temperature survey conducted by scientists at NASA's Earth Observatory.

D. A set of steps that help scientists gather knowledge
You can determine the molar of an unknown solute from the boiling point elevation. When you do an experiment, add a certain known amount of the unknown compound to a solvent, say water. Then, determine the boiling point of the solution. The working equations would be the following:
Temp difference = Boiling pt of solution - Boiling point of pure solvent
Moles solute = (Temp difference)(Mass of solvent)/(Ebullioscopic constant of water)
Molar Mass = Mass of solute/Moles solute
The boiling point of water is 100°C,while the ebullioscopic constant is 0.512 °C/molal.
Answer:
A compound
Explanation:
A compound is chemical entity that is formed when 2 or more elements are joined together in a fixed ratio.
This fixed ratio is simply the numerical values of the numbers of these elements. Take for example in the case of water, one atom of oxygen joins together with two atoms of hydrogen. The fixed ratio here is 1 to 2 or 2 to 1 depending on the reference element.
For example also in methane. The molecular formula of Methane is CH4. The ratio between carbon and hydrogen is 1 to 4 here
