0 |
To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
The transfer of heat by the circulation or movement of the heated parts of a liquid or gas is called:
convection |
|
radiation |
|
conduction |
|
diffusion |

gel |
|
liquid |
|
solid |
An element in a solid state has atoms or molecules that are constricted and do not move freely. Solids maintain a constant volume and shape and exist at a lower temperature than liquids or gases.
Water coming to a boil on a stove, ice melting, and steam from a cup of coffee are all examples of which of the following?
convection |
|
reflection |
|
conduction |
