Question

2. Which of the following statements is false?

(a) The kinetic energy of particles decreases with increasing temperature

(b) The law of conservation of mass is obeyed by chemical reactions

(c) Matter can be changed from one form to another

(d) Matter cannot be created.

Answer 1

A - false option
Because average kinetic energy is directly proportional to temperature

Answer 2

Explanation:

Matter is anything that has mass and takes up space. ... Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
