(Q1) Study Set - Change of State & Thermal Energy

Five friends were talking about the differences among solids, liquids, and gases. They each agreed that the differences have to do with the particles in each type of matter. Which statement do you agree with?

• It has to do with the number of particles.

• It has to do with the shape of the particles.

• It has to to do with the size of the particles.

• It has to do with the movement of the particles.

• It has to do with how hard or soft the particles are.

Why does this puddle disappear after a warm day?

• the surface of the water slowly leave as a gas through evaporation

• the water gets hot enough to boil away

• condensation causes the water to seep into the asphalt

• the liquid particles shrink until they are too small to see
