Methane is a colorless, odorless gas. it oxidizes in air and has a boiling point of -161â°c. which property of methane is a chemical property? color oxidizes in air odor

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.

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.

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current
