A Mineral with a hardness of 7 appears in two different forms. One is a six sided barrel-shaped piece with a pyramid at its top, white in color, and transparent. The other is pink, translucent, has no smooth sides but instead has rounded fracture surfaces. What mineral would this be and how do you account for the greatly different appearances.

Thermal Properties of Materials

In mechanical engineering, the thermal property is represented as the physical quantity that is relevant to the application of heat. The thermal properties are evaluated by variations in any specific material due to low heat or high heat. The quantities that influence the thermal property of the materials are mass, density, temperature, and many others.
