Difference between scalar quantity and vector quantity. |
|
Answer» \tScalarVectorIt has only magnitudeIt has direction and magnitudeOnly one dimensionalIt is multi dimensionalThis quantity changes with the change in magnitudeThis changes with magnitude and directionNormal rules of algebra are applicable hereThere is different set of rules known as vector algebraOne scalar quantity can divide another scalarOne vector cannot divide another vectorIn example of speed, time etc, the distance between the points is scalar quantity not the directionVelocity could be an example because it is measurement of the rate of change of an object’s position\t Scalar has only magnitude . Ex distance .Vector has both magnitude and direction . Ex displacement.Scalar and vector depends upon these both factors. Scalar quantity has only magnitude and no direction while vector quantity has magnitude as well as direction. |

What is dry ice? How it is prepared |
| Answer» Dry ice is solid Carbon\xa0dioxide also referred to\xa0as\xa0"Cardice" sometimesWhen pressure on any gas is increased then the space between the two molecules or atoms gets reduced. The compression of the gas makes it solid. During this process heat energy is released. Carbon dioxide is compressed to get it in solid state.This is called as dry ice. When it comes in contact with any substance it absorbs heat from that substance and forms gas again. | |
