1. Write the differences between heat and temperature.
2. Describe the process of neutralization with the help of an example.
3. Explain the neutralization process with the help of an activity.
question answer
Answers
1. Heat
Heat is a form of energy that can transfer from a hot body to a cold body
Temperature
Temperature is the degree of hotness and coldness of a body.
2. The reaction between an acid and bases is called a neutralization reaction. The result of the reaction is salt and water. For example, when hydrochloric acid(acid) and sodium hydroxide(base) react they form sodium chloride(salt) and water. Also, heat is evolved.
3. Neutralization is a process when acids and bases react to form salt and water. In a reaction to water, neutralization results in excess of hydrogen or hydroxide ions present in the solution. ... If a strong acid is mixed with a weak base then the acid formed is acidic.
Answer:
The reaction between an acid and a base is known as neutralization. Salt and water are produced in this process with the evolution of heat.
Example:
HCl+NaOH⟶NaCl+H

Explanation:
Heat Temperature
Heat is a form of energy that can transfer from a hot body to a cold body. Temperature is the degree of hotness and coldness of a body.
Heat is the total kinetic energy and potential energy obtained by molecules in an object. Temperature is the average K.E of molecules in a substance.
Heat flows from hot body to cold body. It rises when heated and falls down when an object is cooled down.
It has a working ability. It does not have the working ability.
Its SI unit is “Joule”. Its SI unit is “Kelvin”.
It is measured by the calorimeter. It is measured by the thermometer.
It is represented by “Q”. It is represented by “T
