evablogger [386]

Answer:

<em>The correct option is A) they are all classified as pure substances.</em>

Explanation:

Pure air is a term which is used to described air which is free from pollutants or other contaminants. All the substance from which air is made are considered as pure substances. Hence, option A is correct.

Other options, like option C, is false because the components of the air are no chemically bonded to one another. They exist freely. Options D is false because not all the components of air can be classified as an element. For example, carbon dioxide is not an element.

Boiling water transfers energy to an ice cube this is an example of?
Jobisdone [24]
I'd say thermal energy. I say that because if I remember correctly the Second law of thermodynamics describes the energy in this case the boiling water (heat) to areas that are not hot like the ice cube. With heat energy we deal with warm moving to the an area of cold. The molecules in the ice cube from what I remember in college  aren't moving at all hence the block of ice but when heat is added to the ice cube then the molecules in the ice cube start moving and getting excited, which causes the ice cube to start melting, as my bio teacher in college said.


Hopefully this helped and good luck.
