   Sep 18, 2022 · Usually, it is heat transfer through a solid. For example, the metal handle of a pan on a stove becomes hot due to convection. Touching the hot pan conducts heat to your hand. Convection is heat transfer via the movement of a fluid, such as air or water. Heating water on a stove is a good example.

   Conduction, radiation, and convection all play a role in moving heat between Earth's surface and the atmosphere. Since air is a poor conductor, most energy transfer by conduction occurs right near Earth's surface.

   What is the objective of atmospheric chemistry?

   • The objective of atmospheric chemistry is to understand the factors that control the concentrations of chemical species in the atmosphere. In this book we will use three principal measures of atmospheric composition: mixing ratio, number density, and partial pressure. As we will see, each measure has its own applications.

   What are the three main measures of atmospheric composition?

   • In this book we will use three principal measures of atmospheric composition: mixing ratio, number density, and partial pressure. As we will see, each measure has its own applications. The mixing ratio CX of a gas X (equivalently called the mole fraction) is defined as the number of moles of X per mole of air.

   Do substances have to move far?

   • Inside their bodies, in small organisms, substances don't have to move far. The size of their surface, or surface area, defines how quickly they can absorb substances. The size of their volume defines how much of these substances they need. If we represent the cell of an organism by a cube: This is what happens when the cube increases in size:

   • The size of their surface, or surface area, defines how quickly they can absorb substances. The size of their volume defines how much of these substances they need. If we represent the cell of an organism by a cube: This is what happens when the cube increases in size: As the volume increases, surface area does not increase at the same rate.

   How do liquids & gases flow from one place to another?

   • Liquids and gases are fluids. They can be made to flow from one place to another. Convection occurs when particles with a lot of heat energy in the fluid move and take the place of particles with less heat energy. Heat is initially transferred from the Bunsen flame through the glass wall of the beaker by conduction.
