Answer:
convection could be a pot on a stove, radiation could be the sun and heat waves, and conduction could be a cup with coffee.
Explanation:
Conduction occurs when two objects are in direct contact with each other.
Convection is the transfer of heat through liquids and gases. Convection occurs above a hot surface because hot air expands and rises and is replaced by cooler, denser air.
Radiate energy is given off by a hot object and directly absorbed by another cooler object. This cause the cooler object to get warmer. Radiation can occur even if no air is present.
The solution with the lowest pH would mean that it is an acid, specifically a strong acid which completely dissociates into ions in aqueous solution. Among the choices listed above, I think the correct answer is option D. It is nitric acid that will have the lowest pH because it is the only strong acid in the group.

Explanation:
I have attempted to show the sequence of the reaction between carbamic acid and ammonia to form an amide and water and urea.
The reaction first involves the protonation of ammonia to give ammonium carbamate.
When ammonium carbamate is heated to 130-140 degrees, we obtain urea and water as the final products of the reaction
Alteration of the physical form of a drug outside its label is compounding
It is called compounding according to some sources.
