Answer:
heating makes the alcohol molecules of the liquid move faster.
When phenol is heated with zinc dust benzene is obtained.
It would be the Aqueous solution
Answer:
The correct answer is D Air molecules touch the warm ground, heating them up.
Explanation:
There are three types of thermal energy: Conduction, convection, and radiation. Conduction is the process in which energy (also known as heat) is transferred from one object to another by directly touching each other (solids touching solids). Convection is the process in which energy is circulated through the movement of fluids (like liquids or gases), by hot air rising and cool air sinking. Radiation is the process in which energy is transferred from one place to another by electromagnetic waves. An example of this would be feeling warm after being outside in the sun; such as choice B, which is hence incorrect. Choice A is a rephrasing of choice C; both of which are considered convection because air is not a solid, but a gas and this air is <em>rising </em>and<em> sinking</em>. This leaves us with choice D. Choice D would be considered conduction because the air molecules are <em>touching</em> the ground; therefore, being heated <em>directly</em>.
