Why is there a temperature changes when alkali is added to vinegar?

When an alkali (base) is added to vinegar, the acetic acid in the vinegar reacts with the alkali. These reactions are nearly all exothermic, that is, they generate heat as the chemical reaction proceeds. This is observed by a change in the temperature of the aqueous solution and the surrounding air.

If red litmus is added to a alkali?
When red litmus is added to an alkali, its colour changes to blue. This is because an alkali is a base and has the property of turning red litmus paper or red litmus solution to blue.
Does water change the pH level of vinegar?
no. water just dilutes the acid but the PH will not change unless an acid or alkali is added
How the temperature of water changes when sugar is added to it.?
The temperature increase a bit.

Why are enzymes mixed with vinegar less effective?
Enzymes are sensitive to changes in pH and only work with a relatively small pH range. Since vinegar is an acid, the pH of the solution containing the enzymes is changes when vinegar is added.
What do indicators test for?
Indicators are used to test if something for example whether vinegar is an acid or alkali. Due to the pH scale, 1 - 3 is a strong acid, 4 - 6 is a weak acid, 7 is neutral, 8 - 10 is a weak alkali and 11 - 14 is a strong alkali. Vinegar should turn orange when added with an indicator, with the pH of about 3.

Why does the temperature rise as heat is being added when only one phase exists?
I think that the temperature rises when heat is being added because all of the energy has nothing else to focus on so it changes the temperature. Also, adding heat would make the temperature rise.
