Unit 4 Review - 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 heat?

Back

Heat is a form of energy that is transferred between systems or objects with different temperatures.

Front

What is conduction?

Back

Conduction is the process of heat transfer through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation.

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 temperature?

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is the unit of temperature in the metric system?

Back

The unit of temperature in the metric system is Celsius (°C).

Front

What is absolute zero?

Back

Absolute zero is the theoretical temperature at which a system has minimum thermal energy, equivalent to 0 Kelvin or -273.15°C.
