Why is melting a physical property of the wax, but flammability is a chemical property?

1 answer:

6 0

Melting is a physical property and a physical change to wax. We know this because although the wax might melt, it will resolidify into its original form. Flammability, however, is a chemical change because the act of burning involves a chemical reaction between the gases in the air and heat, which cannot be reversed.

a. the ratio of mass to charge of an electron

Explanation:

The experiment permitted the direct measurement of the ratio of mass to charge of an electron.

The charge to mass ratio of an electron was determine by accelerating a beam of cathode rays in magnetic and electric fields.
No matter the gas used in the tube or the nature of the material of the electrodes, the rays were found to have constant charge to mass ratio of 1.76 x 10¹¹coulombkg⁻¹.

Heavy rainfall causes a landslide. Hence, option A is correct.

<h3>What is a landslide?</h3>

A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.

Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability.

Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity.

Hence, option A is correct.
