Chapter 6 Chemical Thermodynamics

Why does an electron in an atom have potential energy?

Define Potential Energy.

Internal energy is a property that is known as _______________________.

In chemistry, all of the energy exchanged between a system and its surroundings may be placed into what two categories?

In an Endothermic Reaction, the products are ususally colder than the reactants because the ________________________ has been absorbed.

Define Specific Heat.

What quantity of heat energy is needed to raise the temperature of 1 pound (454g) of aluminum from 25.0 degree celcius to its melting point, 660. degree Celcius (Csp(Al) = 0.900 J/g.CelciusIn example 6.2

In section 6.3, a pot of water on the stove is boiling at a slow boil. What will happen to the temp. of the water if the stove burner is turned up higher, causing the water to boil more rapidly?

What is the measure of the disorder or randomness in a system?

Arrange the following systems in order of increasing randomness or disorder.1 mol liquid ammonia1 mol gaseous ammonia1 mol solid ammonia
