Question

what is true about the particles in a substance? select all that apply. particles in all states of matter are constantly moving. particles in all states of matter are arranged close together. heating a substance can cause the substance to change state. the way particles move changes when the substances thermal energy changes.

Explanation:

• Particles in all states (solid, liquid, gas) have kinetic energy and are in motion.
• In gases, particles are far - apart, so the statement about all states having particles close together is false.
• Heating can cause phase transitions like melting or boiling.
• Thermal energy is related to particle motion. An increase or decrease in thermal energy changes how particles move.

Answer:

Particles in all states of matter are constantly moving.
Heating a substance can cause the substance to change state.
The way particles move changes when the substance's thermal energy changes.
