E. Long answer questions.1. Differentiate between the following and give examples.a. Physical and Chemical changesb. Reversible and Irreversible changes2. Name the three states in which water exists. How can we change them into one another?3. Explain the factors on which the solubility of a substance in water depends?​

Answer»

Explanation:

Difference Between Physical and Chemical CHANGE

Such changes which do not produces any new substances after the reaction is called as the physical change, whereas the changes which bring out the formation of new substance is named as the chemical change. So we can say that the main difference lies in the chemical composition, where one (chemical change) of the change is involved in altering the composition of the material and thus forms new substance and the other (physical change) brings out alteration in size, shape and colour only.

b

All changes in the world are one of the two types – Reversible changes and IRREVERSIBLE changes. A change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some time, it transforms into ice. But as soon as you take it out of the freezer, it turns into water again. This is a reversible change. Similarly, if you boil water, it evaporates and becomes water vapor. When you COOL this vapor down, it turns back to water.A change which cannot happen backward, that is, it cannot be reversed is called an irreversible change. When you burn a piece of paper, it turns to ash. It cannot become paper again. Your height cannot decrease. These are irreversible changes. They cannot be reversed at all.

c

Just like any substance, water can exist in three different forms, called states: solid, liquid and gas. The state will change when the substance is heated,freezed or melted

d

Solubility is the ability of a solid, liquid, or gaseous chemical substance (referred to as the solute) to dissolve in solvent (usually a liquid) and form a solution. The solubility of a substance fundamentally DEPENDS on the solvent used, as well as temperature and pressure. The solubility of a substance in a PARTICULAR solvent is measured by the concentration of the saturated solution. A solution is considered saturated when adding additional solute no longer increases the concentration of the solution.

9. Give examples to show that friction is both a friend and a foe.10. Explain why objects moving in fluids must have special shapes.​

Answer»

Answer:

friction is a friend

-->it helps US to walk comfortablely on the surface

-->helps to minimize the speed

friction is a foe

-->its causes wear and TEAR in objects

Objects MOVING in fluids face the friction of the fluid that opposes their motion. So Objects moving in fluids MUST have unique shapes called streamlined shapes to reduce the fluidfriction.

Write formula of work ?​

Answer»

The work is calculated by multiplying the force by the amount of movement of an object (W = F * d). A force of 10 newtons, that MOVES an object 3 meters, does 30 n-m of work. A newton-meter is the same THING as a joule, so the units for work are the same as those for energy – joules.

8. Explain why sliding friction is less than static friction.9. Give examples to show that friction is both a friend and a foe.10. Explain why objects moving in fluids must have special shapes.​

Answer»

Explanation:

8.Friction comes into play when irregularities present in the surfaces of two objects in contact get interlocked with each other. In sliding, the time given for interlocking is very small. Hence, interlocking is not strong. ... Because f this reason, sliding friction is less than static friction.

9.Friction is FRIEND (Advantages) :

(i) Friction allows us to grip and catch different objects.

(ii) It helps us to walk comfortably on the surface.

(iii) It helps to MINIMISE the SPEED or to stop the moving objects.

(iv) It helps us to write on paper or blackboard.

(v) The things do not move from their places due to friction.

Friction is foe (Disadvantages) :

(i) Friction causes wear and tear in objects.

(ii) It causes damage the parts of machines.

(iii) The machines or tools require regular maintenance due to which a LOT of money is wasted.

(iv)It reduces the speed of moving objects so more force is required.

(v)It does not allow the free movement of objects.

10.Moving objects in fluid must have special shapes because the drag force or the friction force depends of the shape of the object. Special shapes are designed to minimize the opposing FRICTIONAL force.
