Document Summary
Assigned reading: muller (2010), atoms and heat (pp. 38-66). To prepare for the quiz on this lesson, answer the questions below. Most of the answers can be found in the lecture videos, the rest from your textbook. Which has more mass and why an electrically-neutral. Ion: an atom in which # of electrons does not equal number of protons individual electrical fields: electron microscope can see boundary, visible limit of electron microscope that is set by light.

Briefly describe the 3 ways that heat can flow, and state an example of each one.

Ex. pan heated on a strove: by motion of molecules (convection): air warms, becomes less dense, rises. Warm water rises up and circulates through water. Cold water sinks, warm water rises: radiation: by waves of electromagnetic energy.
