Aug 31, 2017 The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and

A change in which one or more new substances are formed is known as chemical change. For Example, when the iron is exposed to air and moisture, rust formation takes place. Rust is nothing but Iron Oxide a new substance formed out of the reaction. The colour of the surface of the iron also changes. Hence, rusting of iron is a chemical change.

Is boiling water a physical or chemical change? Physical changes alter only the size, shape, form or matter state of a material. Water boiling, melting ice, tearing paper, freezing water and crushing a can are all examples of physical changes. On the other hand, chemical changes are a bit different. In a chemical change, a new substance is formed.

May 06, 2019 Phase Changes - Altering the temperature and/or pressure can change the phase of a material, yet its composition is unchanged, Magnetism - If you hold a magnet up to iron, youll temporarily magnetize it. This is a physical change because its not permanent and no chemical reaction occurs. Mixtures - Mixing together materials where one is not soluble in the other is a physical change.
Jan 14, 2019 Chemical reactions, also called chemical changes, refer to processes that alter chemical compounds, making new substances out of one or more old substances. To put that another way, the atoms of a substance are rearranged when a chemical change takes place. In contrast to physical changes, chemical changes cannot usually be reversed, unless an equivalent chemical reaction takes place.
