How are chemical and physical changes different on a molecular level?
chemical changes involve the breaking of bonds in molecules.
physical changes do not involve molecules.
physical changes cause new molecules to form.

Chemical changes involve the breaking of bonds in molecules.

Explanation: Chemical change is a change in which there is rearrangement of atoms and thus there is formation of new substances which happens by making and breaking of bonds.

Example of chemical change:

Physical change is a change in which there is no rearrangement of atoms and thus there is no formation of new substances , thus no making or breaking of bonds is involved. It only involves changes in states.

Example of physical change:

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
