How Do Car Engines Cool Down?
Circulating coolant through a radiator where the heat is dissipated by a fan.
How Do Heat Pumps Work?
They don't create heat; they use refrigerant to move heat from the cold outdoors to the warm indoors.
How Do Refrigerators Work?
Using a continuous cycle of evaporation and condensation to remove heat.
How Do Space Rockets Stay Cool?
Using ablative coatings and routing cryogenic fuel around the engine nozzle.
How Does a Thermostat Work?
Bimetallic strips, thermistors, and how your house knows when to turn on the heat.
How Does Air Conditioning Work?
Moving heat from the inside to the outside using a closed loop of refrigerant.
What is Absolute Zero?
The lowest limit of the thermodynamic temperature scale where molecular motion stops.
What is Thermodynamics?
The branch of physics dealing with heat, work, and temperature.
