Mid-chapter summary The temperature of a substance is a measure of the average kinetic energy (average speed) of  its atoms and molecules. Evaporation (the transformation of liquid into vapor) is a cooling process that can cool the  air, whereas condensation (the transformation of vapor into liquid) is a warming process  that can warm the air.  Heat is (thermal) energy in the process of being transferred from one object to another  because of the temperature difference between them. In conduction, which is the transfer of heat by molecule-to-molecule contact, heat always  flows from warmer to colder regions. Air is poor conductor of heat. Convection is an important mechanism of heat transfer, as it represents the vertical  movement of warmer air upward and cooler air downward. All objects with a temperature above absolute zero emit radiation. The higher an object’s temperature, the greater the amount of radiation, and the shorter the  wavelength of maximum emission.

Methods for heat transfer in the atmosphere Thermal conduction It requires: physical contact, temperature difference The energy flow is from a body with high T to a body with low T.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
