Module #2: Energy, Heat, and Temperature Flashcards
Energy
The ability to do work.
Work
The force applied to an object times the distance that the object travels parallel to that force
Heat
Energy that is transferred as a consequence of temperature differences
The First Law of Thermodynamics
Energy cannot be created or destroyed. It can only change form
Potential Energy
Energy that is stored
Kinetic Energy
Energy that is in motion
Calorie (cal)
The amount of heat necessary to warm one gram of water one degree Celsius
What is the specific heat of water?
1.000 cal/g.C or 4.184 J/g.C
Kelvin Temperature
An absolute temperature scale
Specific heat
The amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Celsius
Calorimetry
The experimental process that chemists use to measure heat.
1 calorie (cal) is equal to how many Joules?
4.184 Joules
1 food Calorie (Cal) is equal to how many calories (cal)?
1,000 chemistry calories (cal)
What is the formula to convert Fahrenheit to Celsius?
C = 5/9 * (f - 32)
What is the formula to convert Celsius to Fahrenheit?
F = (9/5 * C) + 32
