The value of the real density is not changed, when, for example a metal plate is transformed in wire or a marble object is broken.
The substance formed in a chemical change is called Product.
no, powdering of sugar is a physical change as it does not forms into a new substance
No. Freezing represents a physical change from the liquid to the solid state. The composition of the substance does not change.
Difficult to be correct; chemists consider the higroscopy as a chemical phenomenon but I believe that some physicists has another opinoin.
No, new substances are not formed in a physical change. A physical change is a change in the form or appearance of a substance without changing its chemical composition.
compound
The change were new material is produce is called chemical change.
The mass of a cubic centimeter, also called density, varies with several factors. Gravity, other forms of pressure, temperature, and the type of substance can change what the density, or grams per cubic centimeter, is.
chemical change.
Physical change
The substance formed in a chemical change is called Product.
The energy change that happens when a substance forms from its elements (APEX)
no, powdering of sugar is a physical change as it does not forms into a new substance
It can lose or gain energy or it forms the attractions between particles.
solutions are formed by adding another substance to another substance when this happens it is now called "solution"
No. Freezing represents a physical change from the liquid to the solid state. The composition of the substance does not change.
The substance is a compound, which forms chemical bonds that cannot be physically separated, but only by a chemical change.
