Answer 2

Answer:

Explanation:

[1]The evaporation of water is a physical change. When water evaporates, it changes from the liquid state to the gas state, but it is still water; it has not changed into any other substance

[2 ]Souring milk results in curding, a physical reaction. Yet,chemically it changes because of increased acidity. The proteins become denatured in the process and acid levels increase changing the chemical composition.

[3] The occurrence of an earthquake is a physical change.

It occurs because of the movements generated when tectonic plates hit each other in the earth. Therefore, the chemical changes that would arise underwater would be entirely the result of the earthquake's indirect effects.

[4]The changing seasons

The Earth is tilted 23.5 degrees on its axis, which affects the distribution of the sun's energy across the surface of the planet. ... Around June 22, the northern hemisphere is angled towards the sun, and receives the most direct radiation and the most energy.

[5]  chemical

Glowing of bulb is a chemical as well as physical change. 1. It's a chemical change because electrical energy is converted to heat energy during this process of glowing

mark me as brainliest because i have given answer with full explanation and worked hard to type this answer
