Question | Answer |
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 |
