Answer 1

The correct response is: As the kinetic energy of a substance's atoms increases, its temperature increases, and vice versa. Kinetic energy and temperature are directly proportional. As the kinetic energy of a substance's atoms increases, they move faster and collide with each other more frequently, which results in an increase in temperature. Conversely, when the kinetic energy of a substance's atoms decreases, they move slower and collide with each other less frequently, which leads to a decrease in temperature.

Answer 2

(Question) What is the relationship between kinetic energy and thermal energy?
As the kinetic energy in a substance’s atoms increases, its thermal energy increases, and vice versa.

(Question) What happens when a bowl of ice cream is left uneaten on a counter in a warm room?
Thermal energy is transferred from the air to the ice cream, warming the ice cream.

(Question) What is the relationship between kinetic energy and temperature?
As the kinetic temperature of a substance’s atoms decreases, its temperature decreases, and vice versa.

(Question) What is the best description of heat?
the flow of thermal energy from a warmer substance to a cooler substance

(Question) When thermal energy is applied to water, the water’s temperature rises until 100° C and then stays the same. Which is the best explanation?
When the water reaches 100° C, any increase in thermal energy goes to breaking the bonds between water molecules as the water boils and becomes steam.
