Term
|
Definition
| the responses of the material to changes in temperature |
|
|
Term
| Heat resistance/Heat Resistant Materials |
|
Definition
The ability of a material to maintain its desired mechanical strength at elevated temperature.
Materials with this property are called heat resistant materials |
|
|
Term
|
Definition
| The transition temperature is the point below which a material loses its ductility. |
|
|
Term
|
Definition
| The ability of a material to transfer heat from a body of higher temperature to a body of lower temperature. |
|
|
Term
|
Definition
| The efficiency of a material to absorb thermal energy is known as heat capacity. |
|
|
Term
| Coefficient of linear thermal expansion |
|
Definition
| Nearly all materials expand when heated and contract when cooled.

Term
|
Definition
| When two dissimilar metals are brought in to contact, a voltage is present across the junction. The amount of the voltage depends on the chemical composition and temperature. |
|
|
Term
|
Definition
| Temperature difference between the ends of a wire made of a single metal, then there is a voltage between the ends of the wire. The amount of voltage is determined by the wire material, the chemical uniformity of the material, and the temperature difference. |
|
|
Term
|
Definition
| The scientific action that makes a thermocouple work. It is based on the idea that varying temperatures will produce varying voltages. I.e. the temperature difference between two junctions. |

Term
|
Definition
| Capacitance is the ability of a material or device to store electrical charges. |
|
|
Term
| Relative permittivity/dielectric constant |
|
Definition
| A dielectric material like Mica, placed between the plates of the same capacitor. |
