The temperature of a substance increases as___.

the substance expands

the substance's volume increases

the average kinetic energy of its particles increases


the substance's mass increases

Answer explanation

The temperature of a substance increases as the average kinetic energy of its particles increases. Higher kinetic energy means particles move faster, resulting in a higher temperature.

The movement of thermal energy from a warmer object to a cooler object is called:

heat

motion

temperature

momentum

Answer explanation

The movement of thermal energy from a warmer object to a cooler object is defined as heat. This process occurs naturally, as energy flows from higher to lower temperatures, making 'heat' the correct answer.

Molecules are closest together in a 

solid

liquid

gas

Answer explanation

Molecules are closest together in a solid due to strong intermolecular forces, which keep them tightly packed. In liquids, molecules are still close but can move more freely, while in gases, they are far apart and move independently.

What term describes a liquid changing to a solid?

deposition

freezing

melting

evaporation

Answer explanation

The term that describes a liquid changing to a solid is 'freezing'. During freezing, the molecules in the liquid lose energy and arrange themselves into a solid structure.

MULTIPLE CHOICE QUESTION

45 sec • 1 pt

What is the process called when you add more energy to a substance?

melting

freezing

evaporation

condensation

Answer explanation

The process of adding more energy to a substance typically leads to evaporation, where a liquid turns into a gas. This occurs when molecules gain enough energy to overcome intermolecular forces.
