Question

1 respuestas múltiples 1 punto which phase(s) of matter are compressible? liquid gas solid 2 elección múltiple 1 punto a student notices that when the volume of a syringe is increased, the pressure decreases. which choice correctly explains this observation? gas particles move slower when the volume is lower. more collisions occur when kinetic energy increases. the average kinetic energy of the particles affects the size of the container. fewer collisions occur when there is more space available in the container.

Explanation:

1. Gases have particles that are far - apart and can be pushed closer together, making them compressible. Liquids and solids have particles that are closer together and are not easily compressible.
2. According to the kinetic - molecular theory, when the volume of a container (like a syringe) increases, the gas particles have more space to move. This leads to fewer collisions of the gas particles with the walls of the container, resulting in a decrease in pressure.

Answer:

1. B. Gas
2. D. Fewer collisions occur when there is more space available in the container.
