Question

VI.Give reasons for the following:
1. Preservatives are added to food or beverages
2. All medicines must be taken under proper doctors' supervision and in the comedo
3. Boiling tube is made up of Pyrex
4. Liquids takes up the shape of the container
5. Compressibility is negligible in solids

please help me and answer the question I will make you as brainless.​

Answer 1

Answer:

Explanation:

1.Preservatives are added to food or beverages because of the following reasons:-

1) Prevent decomposition by bacteria and microbes.

2) Reduce the risk of food borne.

3) Preserve the nutritional quality of food.

2.All medicines must be taken under proper doctors supervision and in the correct dose because some medicine has side effect as aspirin not taken in proper dose may cause stomach ulcers similarly paracetamol if taken in high dose may cause liver problems.

3.Boiling tubes can also be used as a replacement for test tubes specially when a larger volume is desired. Boiling tubes are commonly made from Pyrex glass which can tolerate high temperatures.

4.because their particles are loosely packed.. and because of that they also less force of attraction which doesn't allow the molecules to remain at their place or their place is not fixed.. that's why liquids take up the shape of the container in which they are kept..

5.Compressibility is the ability to be reduced to a lower volume when force is applied. Solids are incompressible as their particles are held together. So, we can tell that compressibility is negligible in solids.

thank you!
