Charging by Induction
The previous section of Lesson 2 discussed the process of charging an object by friction or rubbing. Friction charging is a very common method of charging an object. However, it is not…
Methods of Charging
Charging by Friction In Lesson 1, it was explained that atoms are the building blocks of matter. Furthermore, it was explained that material objects are made of different types of atoms…
Polarization
In an earlier section of Lesson 1, it was stated that an electrical attraction would be observed between a charged object and a neutral object. If a charged plastic tube is…
Conductors and Insulators
The behavior of an object that has been charged is dependent upon whether the object is made of a conductive or a nonconductive material. Conductors are materials that permit electrons to flow freely from…
Charge Interactions
Suppose that you rubbed a balloon with a sample of animal fur such as a wool sweater or even your own hair. The balloon would likely become charged and its…
Neutral vs. Charged Objects
As discussed in a previous section of Lesson 1, atoms are the building blocks of matter. There are different types of atoms, known as elements. Atoms of each element are distinguished…
Static Electricity
Basic Terminology and Concepts The Structure of Matter There is a large overlap of the world of static electricity and the everyday world that you experience. Clothes tumble in the…
Calorimeters and Calorimetry
Calorimetry is the science associated with determining the changes in energy of a system by measuring the heat exchanged with the surroundings. Now that sounds very textbooky; but in this last part of Lesson…
Measuring the Quantity of Heat
On the previous page, we learned what heat does to an object when it is gained or released. Heat gains or losses result in changes in temperature, changes in state or…
Calorimetry
What Does Heat Do? Lesson 1 of this chapter focused on the meaning of temperature and heat. Emphasis was given to the development of a particle model of matter that is…
