Question

What is the relationship between a substance’s thermal energy and its kinetic energy?(1 point) Responses There is no relationship between a substance’s thermal energy and kinetic energy. There is no relationship between a substance’s thermal energy and kinetic energy. As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa. As the substance’s thermal energy increases, the kinetic energy of its particles increases, and vice versa. As the substance’s thermal energy increases, the kinetic energy of its particles decreases, and vice versa. As the substance’s thermal energy increases, the kinetic energy of its particles decreases, and vice versa. A substance’s thermal energy is the same as its kinetic energy
Answer
Why does air in a room rise when it gains thermal energy from a heater? (1 point) Responses Warm air always rises. Warm air always rises. Its molecules move around more slowly, so there is more space between them, making it less dense than the air above it. Its molecules move around more slowly, so there is more space between them, making it less dense than the air above it. Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it. Its molecules move around more quickly, so there is more space between them, making it less dense than the air above it. Its molecules move around more quickly, so there is more space between them, reducing its mass.
Answer
How does a simmering pot of spaghetti sauce illustrate convection currents?(1 point) Responses Warmer sauce at the top of the pot is denser, so it sinks to the bottom of the pot, where it is warmed even more. Warmer sauce at the top of the pot is denser, so it sinks to the bottom of the pot, where it is warmed even more. Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed. Warmer sauce at the bottom of the pot is less dense, so it rises, forcing cooler sauce down, where it is warmed. Warmer sauce at the bottom of the pot is denser, so it rises, forcing cooler sauce down, where it is warmed. Warmer sauce at the bottom of the pot is denser, so it rises, forcing cooler sauce down, where it is warmed. The pot is only simmering, so there are no convection currents.
Answer
Which scenario shows conduction?(1 point) Responses Hot soup warms the bowl where it sits. Hot soup warms the bowl where it sits. Hot soup rises to the top of a pot. Hot soup rises to the top of a pot. Bowl of hot soup warms the air around it. Bowl of hot soup warms the air around it. Air above a pot of simmering soup rises, forcing cooler air downward.
