Key Takeaway

KEY TAKEAWAY

• Heat is the transfer of energy of a substance to another substance and is not the same thing as the temperature of a substance.

• Heat is energy and, rather than work, which is the force acting over a distance, it involves the spontaneous transfer of energy from one source to another because of a temperature difference between the two.

• There are several types of heat transfer, such as conduction, convection, and radiation.

• The rate of heat transfer in conduction can be established between two objects.

• The rate of heat transfer in convection is difficult to calculate because there are many factors involved, such as the rising of air as it heats and factors like wind.

• Convection plays a big role in determining the earth’s weather patterns.

• All things will emit electromagnetic radiation. Things that easily absorb electromagnetic radiation are also things that emit electromagnetic radiation more.

• The wavelength of the electromagnetic radiation determines its ability to radiate heat.
