Question

1. what is the definition of volume? the relative size of particles. the amount of space a substance occupies. the average kinetic energy of particles. force applied per unit area. 5. which of the following describes volume of a gas? the size of the container. the number of particles. the average kinetic energy of the particles. the collisions of the particles with the walls of the container. 6. a student increases the volume of a syringe at a constant temperature. what will the student observe during this experiment? the number of particles will decrease. the pressure will increase. the number of particles will increase. the pressure will decrease.

Explanation:

• For question 4: Volume is defined as the amount of space a substance occupies.
• For question 5: The volume of a gas is related to the size of the container it is in.
• For question 6: According to Boyle's law (at constant temperature, $P_1V_1 = P_2V_2$), when volume increases, pressure decreases.

Answer:

1. The amount of space a substance occupies.
2. The size of the container.
3. The pressure will decrease.
