Answer:

Diamonds

Explanation:

The melting point of sugar is 186C

The melting point of oxygen is -218C

The melting point of diamonds are 4078C

Therefore diamonds have the highest melting point.

You can also think of their structures, as diamonds have a covalent network structure, meaning they are really strong and have a high melting point

Oxygen has a covalent molecular structure

Sugar has a much weaker covalent network structure

Water has a high specific heat because: Select one: a. it is a poor insulator b. hydrogen bonds must be broken to raise its temp

Crank

<h2>The required "option is b) hydrogen bonds must be broken to raise its temperature.</h2>

Explanation:

Water has high specific heat due to hydrogen bonds present in it.
The Ionisation of water does not affect the specific heat of the water.
On decreasing the temperature, there is the formation of bonds hence option (d) is wrong.
On increasing the temperature, there is the breaking of bonds hence option (b) is correct.
