Question

Water melts at 0°C. A student observes a liquid that melts at 10ºC. Which conclusion can the student reasonably draw?(1 point)

The molecules in water are farther apart than the molecules in the unknown liquid.
The molecules in water are farther apart than the molecules in the unknown liquid.

The average kinetic energy of water molecules is greater than the average kinetic energy of the molecules in the unknown liquid.
The average kinetic energy of water molecules is greater than the average kinetic energy of the molecules in the unknown liquid.

The electrostatic forces between molecules in the unknown liquid are stronger than the electrostatic forces between water molecules.
The electrostatic forces between molecules in the unknown liquid are stronger than the electrostatic forces between water molecules.

The bonds between water molecules are stronger than the bonds between molecules in the unknown liquid.
The bonds between water molecules are stronger than the bonds between molecules in the unknown liquid.

Answer 1

Answer: C

Explanation: just took the quiz

Answer 2

Electrostatic force between molecules of unknown liquid is higher and stronger than water.

According to the comparison, electrostatic forces between molecules in the unknown liquid are stronger than the electrostatic forces between water molecules. Due to this stronger electrostatic force between molecules of unknown liquid, the unknown liquid needs more heat energy for the breaking of bonds between atoms.

So due to strong electrostatic force between molecules, the unknown liquid needs high temperature than water so we can conclude that electrostatic force between molecules of unknown liquid is higher and stronger than water.
