How are solids different from liquids?

• particles in solids are moving freely around each other.
• particles in solids have no motion.
• particles in solids are vibrating in place.
• particles in solids have more motion than in liquids

A gas

• has a definite shape but no definite volume
• has a definite volume but no definite shape
• has fast-moving particles

Based on the heating curve, what happens to the particles within a substance as it changes from a liquid to a gas?

• When changing to a gas, the particles within a substance break free of each other, move randomly and freely, with no defined volume.
• As the temperature decreases, the particle vibrations within a substance increases, causing them to move faster and more freely.
• When changing to a gas, the particles within a substance slide past each other, move randomly and freely, with a defined volume
• Intermolecular forces hold the particles within the substance close together during the phase change.

According to the heating curve, when a substance is melting, what is happening to the temperature as energy is continually being added it?

• The temperature is increasing as more energy is being added to melt the substance.
• The temperature stays the same as energy continues to be added to melt the substance.
• The temperature is decreasing as more energy is being added to melt the substance.
• The flat curve indicates a change in the temperature allowing for a change in phase.
