Term
| What are the First and Second Laws of Thermodynamics? |
|
Definition
| 1st: Energy cannot be created or destroyed but may be converted from one form to another. 2nd: No machine, actual or ideal, can both continuously and completely transform heat into mechanical energy. Nothing is 100% efficient. |

|
|
Term
| Convert 22° Celsius to °Fahrenheit. |
|
Definition
| Multiply 22° by 1.8 (which equals 39.6), then add 32, which makes a total of 71.6°F. |
|
|
Term
| Convert 105°F to °Celsius |
|
Definition
| Subtract 105° by 32 (which equals 73), and then divide by 1.8 which brings you to 40.56°C |

Term
| How many BTU's are requires to raise the temperature of 500 GALLONS of water from 70°F to 160°F? |
|
Definition
| Convert GALLONS to pounds by multiplying 500 by 8.33 (which equals 4165), then multiply the BTU's from 70°F to 160°F (which is 90 BTU's) by 4165 and the total BTU's is 374,850 BTU's. |

| What is the Latent Heat of Fusion? |
|
Definition
| Heat added to solid to cause a change of state to a liquid. (One pound of Ice at 32°F becomes Water with the addition of 144 BTU's of heat) |
|
|
Term
| What is the Latent Heat of Evaporation? |
|
Definition
| Heat added to a liquid to cause a change of state to a gas/vapor. (One pound of water at 212°F becomes one pound of steam at 212°F when 970.3 BTU's of heat are added) |
|

Term
| What is Sensible Heat and Latent Heat? |
|
Definition
| Sensible Heat is heat that is added to a substance that causes a change in temperature that can be measured with a thermometer. Latent heat is heat that is added to a substance that causes a change of state without a change in temperature. |
