What is stronger chalk or plastic?

Plastic is generally stronger than chalk. Chalk is a soft, brittle material that can easily break or crumble under pressure, while plastic is designed to be durable and resistant to impact. The strength of plastic can vary depending on its type and composition, but overall, it typically has a much higher tensile strength compared to chalk.


Why can a diamond scratch chalk?

No. Hardness is measured on the Mohs Scale, named after German Friedrich Mohs. On this scale Talc (the softest) measures 1, while Diamond (the hardest) measures 10. Glass has a Mohs' scale hardness of around 5.5, so anything above that will have the ability to scratch glass. For example, quartz (Mohs 7), hardened steel (Mohs 8), corundum (rubies and sapphires, Mohs 9),or diamond (Mohs 10). The Mohs scale is purely an ordinal scale, expressing relative hardness in a simplistic way. Carborundum (Mohs 9) is twice as hard as Topaz (Mohs 8), but diamond (Mohs 10) is four times harder than arborundum.


Can a rubber band a piece of chalk or a skirt be more easily broken?

A rubber band would be more easily broken than a piece of chalk or a skirt. Rubber bands are designed to stretch and be flexible, making them more likely to break when stretched beyond their limits. A piece of chalk is more rigid and a skirt is made of fabric, which are not as easily broken by stretching or bending.


What are the materials needed in baseball?

Why will chalk dust on a plastic sheet placed over a bar magnet not show the shape of the magnetic field?

Chalk dust (calcium carbonate) is not magnetisable.


Which has more force of attraction an iron nail a piece of chalk and a rubber band?

The iron nail has the greatest force of attraction due to its magnetic properties, followed by the piece of chalk which has minimal attraction, and the rubber band has the least as it is non-magnetic and non-conductive.


Can synthetic rubber be painted with chalk board paint?

Yes, synthetic rubber can be painted with chalkboard paint, but proper surface preparation is essential for good adhesion. Cleaning the rubber surface and using a primer designed for plastic or rubber can help the paint adhere better. It's important to choose a high-quality chalkboard paint and allow adequate drying time between coats to achieve the best results. However, keep in mind that the flexibility of synthetic rubber may affect the durability of the paint over time.


Why does a piece of chalk wear out as it is used on a blackboard?

With every stroke of the chalk piece it leaves some of the chalk on the board. This abrasion of the piece of chalk causes it to wear down. This is similar to why the rubber tyres of cars wear down when they are driven over a road surface.
