Particle Model of Matter Quizzes - Test Your Understanding

Question 1

According to the particle model of matter, how would the behavior of a gas change if it were subjected to extremely high pressure and low temperature?

Question 3

Explain how the particle model of matter can be used to explain two properties of solids: their hardness and elasticity.

Accepted Answer

In solids, particles are closely packed together and have a regular arrangement, explaining their hardness and elasticity.

Answer

In solids, particles are spread out and have a random arrangement, making them hard and elastic.

Answer

Solids have weak intermolecular forces between their particles, which explains their hardness and elasticity.

Answer

Solids have a low density, making them hard and elastic.

Question 4

Explain how the particle model of matter accounts for the diffusion of gases. Provide a demonstration that illustrates your explanation.

Accepted Answer

Diffusion in gases occurs because gas particles move randomly, colliding with each other and spreading out over time.

Answer

Diffusion is not possible in gases because gas particles are too spread out to interact.

Answer

Gas particles are attracted to each other, preventing diffusion.

Answer

Diffusion in gases is caused by the presence of holes or empty spaces between gas particles.
