Study Notes
- Atomic structure consists of a nucleus with protons and neutrons, surrounded by electrons.
- Reflectivity is the amount of light reflected from a material.
- Thermal stress occurs when a body can't expand or contract freely due to temperature changes.
- Melting point is the temperature where a solid transitions to a liquid.
- Crystalline solids have a sharp melting point, while amorphous solids soften gradually.
- Toughness is the ability of a material to absorb energy without rupturing.
- Hardness is the ability of a metal to cut another metal.
- Hardness includes resistance to wear, scratching, deformation, and machinability.
- Hardness can be measured through various tests like Brinell, Rockwell, Vickers, and Shore.
- The toughness of a material decreases when it is heated.
