Explanation:

When a substance is heated then its molecules gain kinetic energy and they start to collide rapidly with each other.

As a result, when we place another object of a lower temperature then molecules of the hotter object tends to lose excess of energy.

Hence, this energy is transferred to the adjacent colder object. This means that heat flows from a hotter object to a colder object.

Thus, we can conclude that heat always flows from a hotter place to a colder place.

As you go down deeper, less water is able to receive the heat from the sun or other sources, so naturally they would be cooler than the water at the top

Draw the structure of (z)-3-bromo-6-methyl-2-heptene. be sure the stereochemistry is drawn clearly.

Explanation: In IUPAC, E-Z convention is given for describing the cis - trans notation to the isomers. According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as Z-form and if the highest priority groups are on opposite side, it is known as E-form.

We are given (Z)-3-bromo-6-methyl-2-heptene, in this the highest priority groups are bromine on one side and methyl- group on another side.

The structure is provided in the image below.
