Chapter 5 Notes The study of energy and its transformations is called thermodynamics. An aspect of thermodynamics that deals with the relationships between chemical reactions and energy changes involving heat is called thermochemistry. 5.1 The Nature of Energy Energy is defined as the capacity to do work or produce heat. Work is the energy used to cause an object with mass to move. Heat is the energy of an object that causes its temperature to increase. Kinetic and Potential Energy

1. What are the advantages and disadvantages of the different types of light and electron microscopes discussed in Chapter 3 that are used to study microorganisms? Focus your response in terms of the following parameters The disadvantage of using a light microscope is its inability to magnify a specimen as great as an electron microscope. An electron microscope can magnify up to 500‚000 times‚ whereas‚ a light microscope can only magnify an object up to 2000 times. The resolving power or resolving

enlargement of a specimen while resolution is the ability to distinguish detail or the ability to distinguish between distinct points. There are two types of microscope known as light microscope and electron microscope. Contrast is the selective or differential absorption of light by a specimen directly correlated to the density gradients in and of the specimen. A light microscope utilizes light that can be altered by a filter and condenser to visualize a specimen. There are many specific light microscopes
