What is the property that allows matter to be bent flattened or hammered without breaking is?

Arod of some material 0.20 m long elongates 0.20 mm on heating from 21 to 120°c. determine the value of the linear coefficient of thermal expansion [in (degrees c)^-1] for this material.

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.
