Question

match each word with the correct description. answer choices: the rising of warm fluid and sinking of cool fluid in a cycle the energy a single particle has because of its motion the total energy of all particles moving in a material how tightly packed particles are in a given amount of space drag the answer choices to the correct category over here! thermal energy kinetic energy convection density question 7 describe what happens to the motion and spacing of particles during a convection cycle. use the words thermal energy and density in your answer. use at least 2 complete sentences.

Explanation:

• Convection: The rising of warm fluid and sinking of cool fluid in a cycle. This is the basic definition of convection.
• Kinetic Energy: The energy a single particle has because of its motion. Kinetic energy is related to the motion of individual particles.
• Thermal Energy: The total energy of all particles moving in a material. Thermal energy is the sum of the kinetic energies of all particles in a substance.
• Density: How tightly packed particles are in a given amount of space. Density is a measure of mass per unit volume, which relates to particle packing.

For the description of what happens to the motion and spacing of particles during a convection cycle:
When a fluid is heated (thermal energy is added), the particles gain kinetic energy. They move faster and spread out more (spacing increases), which makes the fluid less dense. This less - dense warm fluid rises. As it rises, it cools (loses thermal energy), the particles slow down (motion decreases), get closer together (spacing decreases), and the fluid becomes more dense, then it sinks.

Answer:

• "The rising of warm fluid and sinking of cool fluid in a cycle" → Convection
• "The energy a single particle has because of its motion" → Kinetic Energy
• "The total energy of all particles moving in a material" → Thermal Energy
• "How tightly packed particles are in a given amount of space" → Density

For the convection cycle description: When thermal energy is added to a fluid, particles gain kinetic energy, move faster, and spread out (spacing increases, density decreases), causing the fluid to rise. As it cools (loses thermal energy), particle motion slows, spacing decreases, density increases, and the fluid sinks.
