Thermodynamics

Front

What is thermodynamics?

Back

Thermodynamics is the branch of physics that deals with the relationships between heat and other forms of energy.

Front

What is the first law of thermodynamics?

Back

The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is the second law of thermodynamics?

Back

The second law of thermodynamics states that the total entropy of an isolated system can never decrease over time.

Front

What is entropy?

Back

Entropy is a measure of the disorder or randomness in a system.

Front

What is the third law of thermodynamics?

Back

The third law of thermodynamics states that as the temperature of a system approaches absolute zero, the entropy approaches a constant minimum.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, calculated as PE = mgh.

Front

What is sound energy?

Back

Sound energy is the energy carried by sound waves, which are vibrations that travel through a medium such as air or water.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is the difference between heat and temperature?

Back

Heat is the transfer of thermal energy between systems, while temperature is a measure of the average kinetic energy of particles in a substance.
