Answer from: pindu

Explanation:

Physical properties are those properties which are measurable and describe state of some physical system.

The changes in physical properties are observable and physical properties are quantitative which means they can be measured.

For example,take height of a person as a physical property.

Height is measurable and describes how high a person is.

We can observe if height of a person is changed.

Chemical properties are those properties that describe how the system behaves in chemical reactions.

For example take enthalpy of ionisation.This property will tell us whether the atom forms a ion or not in the reaction.

Difference between physical and chemical properties:Physical Properties:Physical properties of a substance can be measured through initial observations without any alteration in its composition. It includes properties that define the physical structure and visual identification of a substance. Physical properties of a matter can be described without changing its chemical properties. For e.g. mass, density, volume, colour, boiling point, melting point or its phase. Chemical Properties:Chemical properties are observed only after performing a chemical reaction and this result in a change in its original chemical composition. Eg: Flammability, heat of combustion, reactivity, chemical stability, etc. Chemical properties of sodium define it to be a highly reactive metal which violently reacts with water and gives rise to an exploding reaction. When heated, it burns with a bright golden flame. When treated with acids, it gives out hydrogen gas.

Example:

Sodium metal can be defined by its physical properties to be a solid, silvery-white shiny metal with a melting point of 97.82⁰C and boiling point of 881.4°C. It is slightly less dense than water, 0.968 grams per cc.

Answer from: Quest

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.

Ablock of mass m = 2.5 kg is attached to a spring with spring constant k = 740 n/m. it is initially at rest on an inclined plane that is at an angle of theta= 26 with respect to the horizontal, and the coefficient of kinetic friction between the block and the plane is uk = 0.17. in the initial position, where the spring is compressed by a distance of d = 0.16 m, the mass is at its lowest position and the spring is compressed the maximum amount. take the initial gravitational energy of the block as zero. the block's initial mechanical energy is 9.472 j.b. if the spring pushes the block up the incline, what distance l in meters will the block travel before coming to rest? the spring remains attached to both the block and the fixed wall throughout its motion.
