You can decrease the thermal energy of a metal block by allowing it to cool in a cooler environment, such as placing it in contact with a cooler surface or exposing it to a colder surrounding. Alternatively, you can reduce its thermal energy by transferring heat away from the metal block through a process like conduction or convection.

Where an decrease in thermal energy is occurring?
A decrease in thermal energy can occur when heat is transferred from an object to its surroundings, causing a loss in temperature. This could happen through conduction, convection or radiation as the object releases heat energy to its cooler surroundings, resulting in a decrease in thermal energy.
What does it mean when the heat energy is negative?
A negative value for heat energy typically indicates that heat is being released or removed from a system, resulting in a decrease in temperature. This could occur during processes like heat transfer, where heat flows out of a system, leading to a decrease in thermal energy.
Name at least two ways that thermal energy in air can be decreased?
Thermal energy in air can be decreased by venting the air to a cooler environment or by passing it through a heat exchanger to transfer heat to a cooler medium.
What forms of energy could be identified at the lit headlight?
Light energy, electrical energy, and thermal energy could be identified at a lit headlight. The light energy is emitted as visible light, the electrical energy powers the light bulb, and the thermal energy is produced from the heat generated by the light.
When is heat thermal energy?
Heat is a form of thermal energy that results from the motion of atoms and molecules within a substance. It is transferred between objects with different temperatures due to the difference in their thermal energy.

What causes kinetic energy to change to thermal energy?
Kinetic energy is converted into thermal energy through friction. When a moving object is stopped by some sort of friction, the decrease in the object's kinetic energy is converted into equal amounts of thermal energy. Considering the Law of Conservation of Energy states that the energy in a closed system remains constant, it is impossible that the kinetic energy of an object could be lost altogether, so rather it is simply transformed into a different type of energy, thermal energy.
What does it mean when the heat energy is negative?
A negative value for heat energy typically indicates that heat is being released or removed from a system, resulting in a decrease in temperature. This could occur during processes like heat transfer, where heat flows out of a system, leading to a decrease in thermal energy.

What brings thermal energy to the surface?
Thermal energy is the total amount of energy in a substance. A lot of the things could bring it to the "surface"
What is chemical energy transformed to?
It could be transfered to sound, thermal, and potential energy.
What forms of energy could be identified at the lit headlight?
Light energy, electrical energy, and thermal energy could be identified at a lit headlight. The light energy is emitted as visible light, the electrical energy powers the light bulb, and the thermal energy is produced from the heat generated by the light.
Benjamin Thompson proved the existence of energy to observers by showing that kinetic energy could be converted to?
thermal energy
Is thermal energy the energy of the future?
Yes, it very well could be, although people are working on vegetable energy.
When is heat thermal energy?
Heat is a form of thermal energy that results from the motion of atoms and molecules within a substance. It is transferred between objects with different temperatures due to the difference in their thermal energy.
What kind of energy could resistance in an electrical wire be converted to?
Thermal
How could you increase the kinetic thermal energy of a liquid?
You can increase the kinetic thermal energy of a liquid by heating it. When you add heat to a liquid, the temperature increases, which in turn increases the kinetic energy of the molecules in the liquid. This causes the molecules to move faster and leads to an increase in the thermal energy of the liquid.
