Under Pressure: From Solid to Liquid to Gas
In This Chapter
Handling heat convection and heat conduction
Dealing with heat radiation
Using Avogadro's number
Working with molecular motion
Heat is the transfer of thermal energy between objects, usually through conduction, convection, or radiation. Thermal energy is the energy associated with the temperature of an object.
This chapter is concerned with all kinds of things heat related — rate of heat, for example, which is about how fast thermal energy travels along iron bars, aluminum pot handles, and more. Want to know how long you can hold that pot over an open flame? This chapter is for you.
You also find here the famous ideal gas law, which connects the pressure, volume, and temperature of a gas. Want to know the pressure of a volume of gas at a particular temperature? Just turn to the ideal gas law, and it'll give you the answer.
Plenty of thermodynamics comes up in this chapter, from how fast thermal energy travels to what pressure gas has at a certain temperature.
In this chapter, you discover the three primary means ...
