Answer:
Thermal energy is transferred from hot places to cold places by conviction.
Explanation:
That is false, if it has more mass you need more force
Heat transfer is the phenomenon that occurs when the two objects are in the vicinity of each other and by increasing the area of their contact. Thus, option B is correct.
<h3>What is heat transfer?</h3>
Heat transfer is a process that flows the heat from one system to another, and is because of the difference in the temperature of the two objects that are part of the system.
The methods like conduction, convection, and radiation transfer the heat from the surface area to the other object. The heat gets transferred from the area of high to the low temperature.
Therefore, option B. by increasing the surface area the heat transfer increases.

<h3><u>Answer;</u></h3>
a. CH3CO2H
<h3><u>Explanation;</u></h3>
- An Arrhenius acid is a substance that dissociates in water to form hydrogen ions or protons. In other words an Arrhenius acid increases the concentration of H+ in aqueous solution.
- Acetic acid (CH3CO2) dissociates in aqueous solution to form hydrogen ions (H⁺) and acetic anion (CH₃COO⁻). Therefore, it is an Arrhenius acid.
- The equation of dissociation;
CH₃COOH(aq) ⇄ CH₃COO⁻(aq) + H⁺(aq).
This is a chemical reaction.
