Changes in which no new kinds of matter are produced are called

Physical change

Explanation:

In physical change , identity of the matter is never changed so no new matter is produced. In this, there is no change in physical and chemical properties of the substance. In this, only shape, size or state of the matter changes. For example, boiling water, mixing together substances like salt and water. The physical change does not change the nature of the substance. The nature changes only if a chemical change also takes place along with the physical change.

Chemical change results in changing of a substance into a entirely new form. Chemical changes are mostly irreversible.

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
