• decreasing the temprature decreaseases the speed of particles

• particles of matter are not always in motion

• particles of matter have mass

• temperature has no effect on particle motion

• increasing the temperature decreases the speed of particles

• matter cannot be created or destroyed

• increasing the temperature increases the speed of particles

• all matter is made of particles

• particles of matter are always in motion

What is the relationship between temperature and kinetic energy?

• Temperature has no influence on kinetic energy

• Kinetic energy is only influenced by the mass of an object

• Higher temperatures will cause lower kinetic energy

• Temperature and kinetic energy are closely related. The higher the temperature, the higher the kinetic energy of the particles within an object. Conversely, the lower the temperature, the lower the kinetic energy of the particles within an object.

What distinguishes between gas, liquid, and solid particles?

• The difference between gas, liquid, and solid particles lies in the shape of the particles.

• The difference between gas, liquid, and solid particles lies in the color of the particles.

• The difference between gas, liquid, and solid particles lies in the temperature of the particles.

• The difference between gas, liquid, and solid particles lies in the distance and compactness between the particles.

Why are gas particles considered to have constant random motion?

• Because they are influenced by a magnetic field

• Because they continuously collide and interact with other particles around them.

• Because they have a very large mass

• Because they continuously move in one direction

How does the kinetic energy of gas particles change as the temperature increases?

• The kinetic energy of gas particles will remain the same as the temperature increases.

• The kinetic energy of gas particles will decrease as the temperature increases.

• The kinetic energy of gas particles will change randomly as the temperature increases.

• The kinetic energy of gas particles will increase as the temperature increases.

What happens to gas particles when the temperature decreases?

• Gas particles will evaporate and become denser gas

• Gas particles will remain in the same state without any change

• Gas particles will lose their kinetic energy and eventually form a liquid or solid.

• Gas particles will gain kinetic energy and become more mobile

How do solid, liquid, and gas particles differ in terms of the distance between particles?

• Solid particles have a looser distance between particles than liquid particles

• Solid particles have a very close distance between particles, liquid particles have a looser distance between particles than solid particles, and gas particles have the furthest distance between particles.

• Liquid particles have a very close distance between particles

• Gas particles have a closer distance between particles than solid particles

Why do gas particles have higher kinetic energy than solid particles?

• Gas particles have higher kinetic energy because they have more space and freedom to move.

• Gas particles have higher kinetic energy because they have a more complex internal structure.

• Gas particles have higher kinetic energy because they have a stronger gravitational pull.

• Gas particles have higher kinetic energy because they have a greater mass than solid particles.

What causes gas particles to have random motion?

• Air pressure pushing the gas particles

• Magnetism directing the motion of gas particles

• Gravity pulling the gas particles

• Interactions and collisions between gas particles.

How does the kinetic molecular theory explain the behavior of gases?

• The kinetic molecular theory explains the behavior of gases by describing that gases consist of particles that move randomly and collide with each other and with the walls of the container.

• The kinetic molecular theory explains the behavior of gases by describing that gases do not consist of particles.

• The kinetic molecular theory explains the behavior of gases by describing that gases consist of particles that move in a regular and orderly manner.

• The kinetic molecular theory explains the behavior of gases by describing that gases consist of particles that are stationary and do not move.
