Which statement about the temperatures of phase changes and electrostatic forces holding the molecules is correct?(1 point) The strength of the forces between molecules in a substance is strongest at higher temperatures
The temperatures at which a substance changes phases is dependent of the size of the molecules in the substance.
The strength of the forces between molecules in a substance depends on the number of filled electron shells
The temperatures at which a substance changes phases indicate the relative strength of the forces between molecules in the substance.

gas, liquid, solid
solid, liquid, gas
gas, solid, liquid

Which change happens when water boils?(1 point)
The forces between water molecules and the bonds between the atoms in the water molecules break.
The forces between water molecules break, and the bonds between the atoms in water are unchanged.
The forces between water molecules are unchanged, and the bonds between the atoms in the water break.
The forces between water molecules become stronger, and the bonds between atoms in the water remain unchanged.

A sample of calcium carbonate is cooled. Which change happens to the molecules of calcium carbonate in the sample?(1 point)
The molecules break apart and then form stronger forces.
The molecules vibrate more and weaken the forces.
The forces weaken, and the molecules move around.
The forces strengthen, and the molecule structure becomes more rigid.
The boiling point of acetone is lower than the boiling point of ethanol. Based on this information, which conclusion can be drawn about the two substances?(1 point)
The intermolecular forces in ethanol are stronger than the intermolecular forces in acetone.
The intramolecular bonds in ethanol are stronger than the intramolecular bonds in acetone.
The intramolecular bonds in acetone are stronger than the intramolecular bonds in ethanol.
The intermolecular forces in acetone are stronger than the intermolecular forces in ethanol.
