Expansion, Contraction, Remains unchanged. Expansion :materials like iron, steel expand on heating due to molecular expansion. And some materials like type metal contracts on heating. Rubber bands are unusual because they are made from loosely-packed chains of atoms. These long molecules behave in a special way because of a property in physics that we call Entropy. Stone on heating remains unchanged read less

On heating a body it increases in temperature. Expansion of molecules change of state of matter Heating itself says adding hotness to the body , which then the intensity of heat is increased which is the temperature. The spacing between the molecules increases which is the molecular expansion. On heating the atoms which are always moving within a substance begin to vibrate thus increases the space between them. And expansion occurs thus size of the body is increased but the mass of the body remains the same. Because of this molecular expansion there occurs the change of state of matter. Also on heating the velocity of the atoms inside gets increased read less

The changes can be expansion, contraction and state. Metals can be expanded by heating. Plastic materials can be contrasted by heating and by heating ice it becomes water.

Changes which can be brought by heating is expansion,contraction and change of state Expansion - An object may expand because of expanding molecules Contraction - An object may contract on losing its molecules Change of state- An object may deform or change its shape because of heating

1. change in state..sold, liquid, or gas 2.can reduce pressure by creating lower pressure area eye 3.can accelerate the motion of molecules by giving them additional kinetic energy

I depends on material you are applying heat.material which are not conductors wont undergo any expansion or phase change. if the medium is a conductor it will go through changes. solid metals expand and on heating and if heated to melting point it will melt to liquid. in some processes heating is used...

I depends on material you are applying heat.material which are not conductors wont undergo any expansion or phase change. if the medium is a conductor it will go through changes. solid metals expand and on heating and if heated to melting point it will melt to liquid. in some processes heating is used to increase the hardness of steel by heating to a high temperature and cooling suddenly which is called heat treatment. Gases expand and their density reduces by heating liquids convert to gaseous state while heating in some cases gases are cooled to a temperature below certain temperature point and converted to liquids and solids eg: dry ice made from carbon dioxide read less

1. Physical state of a substance can be changed by heating. 2. Heating can also cause expansion. Molecules will gain energy from heating and move apart, so their inter-molecular distance will increase and hence expansion will take place. 3. In biological prospective, if heating is done under specific...

Why sandy-loam soil is used for grooving cotton?
The soil which is neither sand, silt, or clay is called loam. Loam soils contain more nutrients, moisture and humus than sandy soils. So they use these soils for grooving cotton.
