Boiling Hot!
Water boils at _______ degrees celsius?
What is 100 C?
This is the equation to relate the heat gained or lost by an object, the water and the calorimeter. This is also known as the calorimetry equation.
-qobject = qwater + qcalorimeter
Define work.
The force applied to an object times the distance that the object travels parallel to that force.
A material with a low heat capacity is a good insulator.
True or false
False.
A low specific heat capacity means that it takes less energy to heat the object. A material such as styrofoam is a good insulator because it is a poor heat conductor.
This is the equation to measure heat.
*Extra points for naming each variable.
q=m x c x (change in T)
Define kinetic energy.
extra points for an example
Energy in motion.
*heat, lightning and flames
True or False:
While water boils, its temperature stays constant.
What is true?
Energy cannot be created or destroyed, it can only change forms.
Explain energy and work.
Energy is the ability to do work.
the amount of energy needed to raise the temperature of 1 gram of water by 1 degree Celsius
An object is (gaining or losing) energy when its temperature starts to increase.
Gaining energy
Define potential energy.
extra points for an example
stored energy
*all matter has stored energy so any substance would be a good example
Explain specific heat in terms of temperature.
Specific heat is the amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Celsius.
Explain how a calorimeter works.
-An insulated container is holding a liquid (usually water)
-An object with a known temperature is dropped into the calorimeter.
-the heat absorbed by the water is equal to the heat released by the object.
