Thermal Energy

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of the particles in a substance.

What is the process of defining a problem in engineering?

Back

Defining a problem is the first step in the engineering design process, where engineers identify the issue that needs to be solved.

Front

What do engineers do?

Back

Engineers design and build things to solve problems.

Front

What is a chemical reaction?

Back

A chemical reaction is a process that creates new substances from existing substances and can absorb or release thermal energy.

Front

What is the state of matter where atoms are far apart and vibrate?

Back

Gas is the state of matter in which atoms vibrate so much that they are far apart.

Front

What is water vapor?

Back

Water vapor is water in gas form.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. The faster an object moves, the more kinetic energy it has.

Front

What is temperature?

Back

Temperature is a measure of how hot or cold something is, which relates to the average kinetic energy of the particles in a substance.

Front

What is the difference between thermal energy and temperature?

Back

Thermal energy is the total energy of all the particles in a substance, while temperature is a measure of the average energy of those particles.

Front

What happens to thermal energy during a phase change?

Back

During a phase change, thermal energy is either absorbed or released, causing the substance to change from one state of matter to another.
