Question

Q.Give reasons for the following-


A) A diver is able to cut through the water in the swimming pool


B) Total mass of reactants is always equal to total mass of products


C) Solids have generally high density as compared to liquids and gases​

Answer 1

Answer:

A. inertia of motion

B.law of conservation of mass

C. solids and liquids have high densities because their particles are packed closely together, whereas gases have low densities because their particles are very far apart.

Answer 2

Here's your answer mate

A) A diver will be able to pass through water if there is availability of space between the particles and the forces of attraction between the liquid particles are not very strong.

B) According to the law of conservation of mass , during a chemical reaction, the total mass of the products must be equal to the total mass of the reactants. In other words, mass cannot be created or destroyed during a chemical reaction, but is always conserved.

C) solids and liquids have high densities because their particles are packed closely together, whereas gases have low densities because their particles are very far apart.
