QuestionAnswer
Flames are a form of... energy
Energy is the ability to do work
Work The force applied to an object times the distance that the object travels parallel to that force
Energy is basically the ability to cause motion
Heat is Energy that is transferred as a consequence of temperature differences
Heat is really just energy
The First Law of Thermodynameics Energy cannot be created or destroyed. It can only change form
Potential energy Energy that is stored
Kinetic energy Energy that is in motion
The metric system's unit of energy Joule
Joule is named after... James Prescott Joule
1 Joule energy is spent by Lifting a 102-gram object straight up at a constant speed for 1.0 meter
If ice and water are thoroughly mixed, the.... temperature will stay the same, regardless of the ratio
Boiling water is always the... same temperature, 100.0 C or 32.0 F
The temperature of ice and water is always 0.0 C or 212.0 F
C= 5/9 (F-32)
F= 9/5 (C)+32
K= C+237.15
Calorie (cal) The amount of heat necessary to warm one gram of water one degree Celsius
1 calorie= 4.184 Joules
1 food calories (Cal) = 1,000 chemistry calories (cal)
Measuring heat q=m.c.DeltaT
q= amount of heat absorbed or released
m= the mass of the object
c= specific heat
Delta T= The change in temperature
Delta T= (equation) Tfinal-Tinital
Specific Heat The amount of heat necessary to raise the temperature of 1 gram of a substance by 1 degree Celsius
Copper's specific heat 0.3851 J/gC
Iron's specific heat 0.4521 J/gC
Glass' specific heat 0.8372
Aluminum's specific heat 0.9000
Water's specific heat 4.184
Calorimetry equation -qobject=qwater+qcalorimeter
