Chem-Module 2
| 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 |
