Term
The person who build the first steam engine.
Definition
Thomas Savery
Term

Name of the steam engine invented by Thomas Newcomen.

Definition
the atmospheric engine
Term
Person who's steam engine had steam driving the piston in two directions and was largely responsible for the rapid development of the Industrial Revolution.
Definition
James Watt
Term
Early theory of matter put forth by Empedocles stated that matter was composed of these four elements.
Definition
earth, air, fire, and water
Term
This was thought to be an invisible fluid that was contained in all objects that could burn, and that when these objects burned this fluid flowed out of the object.
Definition
phlogiston
Term

This was thought to be a massless fluid found in all substances. It could not be created nor destroyed, but could flow from one substance to another, and always flowed from warmer objects to cooler objects.

Definition
caloric
Term
The quantitative definition, put forth by Joseph Black, of what a calorie was equal to.
Definition
the amount of caloric that would raise the temperature of 1g of water by 1oC
Term
What Count Rumford said heat was.
Definition
heat was energy
Term
Energy is measured in this unit.
Definition
the Joule (J)
Term
Definition of work.
Definition
work is a measure of energy.
Term
Mathematical formula for calculating work.
Definition

W=Fd

work = force x displacement

Term
When given a graph of force vs. time, the method of determining work.
Definition
find the area under the line
Term
The modern definition of the calorie.
Definition
the amount of energy that must be added to 1g of water to increase its temperature by 1oC.
Term
One calorie is equivalent to how many joules?
Definition
1 cal = 4.186 J
Term
The law of conservation of energy.
Definition
energy cannot be created or destroyed only changed from one form to another
Term
Energy of motion.
Definition
kinetic energy
Term
The name of the current theory of heat.
Definition
the kinetic-molecular theory
Term
The term that has replaced the word "heat".
Definition
thermal energy
Term
The modern definition of heat.
Definition
the transfer of thermal energy from one object to another.
Term
The term for the amound of energy required to raise the temperature of 1 g of a substance by 1 oC.
Definition
specific heat capacity
Term
The symbol used for specific heat capacity.
Definition
c
Term

The specific heat capacity of water.

Definition
4.186 J/goC
Term
Definition of temperature.
Definition
a measure of the average kinetic energy of the individual atoms or molecules in a substance
Term
The field of physics that deals with forces and motion involving heat.
Definition
thermodynamics
Term

The first law of thermodynamics

Definition
energy cannot be created nor destroyed only transformed from one form to another or transferred from one object to another
Term
The second law of thermodynamics
Definition

it is not possible for any process to remove thermal energy from an energy source and convert it entirely to work

(no process can be 100% efficient)
