Answer : The chemical property of methane is, Oxidizes in air.

Explanation :

Physical property : It can be observed or measured when no changes occurs in the chemical composition of the substance.

For example : color, boiling point, melting point, odor, density, etc.

Chemical property : It can be observed or measured when changes occurs by the chemical reaction in the composition of the substance.

For example : oxidation, combustion, toxicity, rusting, etc.

From the given options, methane oxidizes in the air shows the chemical property. While the other options, colorless, odorless and boiling point shows the physical property.

When methane react with oxygen to produce carbon dioxide and water.

CH_4(g)+O_2(g)\rightarrow CO_2(g)+H_2O(l)

Therefore, the correct answer is, Oxidize in air.

Answer: oxidizes in air

Explanation: Chemical property is the property which deals with change in chemical composition of the substance.

Physical change is the property which deals with change in physical state of the substance.

CH_4+2O_2\rightarrow CO_2+2H_2O

The above equation represents the oxidation of methane to form carbon dioxide and water. Thus the chemical composition has changed and is a chemical property.

Color and odor only involves no change in chemical composition.

Where do astronauts get drinking water from
k0ka [10]

Answer:

Nearly all of the water astronauts drink and shower with comes from their urine and sweat. Storage is hard to come by aboard the International Space Station. Even if a rocket had room to ferry thousands of pounds of water and oxygen to supply a six-month mission, you'd struggle to find anywhere to stash it.
