How does temperature affect the state of matter?

• Higher temperatures always turn solids into gases

• Lower temperatures always turn gases into solids

• Temperature changes can cause phase changes between solid, liquid, and gas

• Temperature has no effect on the state of matter

Compare the kinetic energy of particles in a liquid to those in a solid.

• Particles in a liquid have less kinetic energy than in a solid

• Particles in a liquid have more kinetic energy than in a solid

• Particles in a liquid have the same kinetic energy as in a solid

• Kinetic energy in a liquid is unpredictable

Explain why gases have an indefinite shape and volume.

• Because gas particles are tightly packed

• Because gas particles are fixed in place

• Because gas particles move freely and fill the container

• Because gas particles are heavier than solids

What is the effect of increasing temperature on the kinetic energy of gas particles?

• It decreases the kinetic energy

• It has no effect on the kinetic energy

• It increases the kinetic energy

• It makes the kinetic energy constant

Analyze the relationship between temperature and phase changes in water.

• Water freezes at higher temperatures

• Water boils at lower temperatures

• Water changes from solid to liquid at 0°C and from liquid to gas at 100°C

• Water does not change phases with temperature
