Ways to Bring About a Change

Now the question arises, what makes a change occur? In other words, how can we bring about it? There are quite a few ways in which one can bring about a change in the form of an object. Some of these ways are listed below:

Temperature

Change can be caused due to a fluctuation or alteration in temperatures. Such a change in most cases changes the form of the object. Revisiting the example of water and ice, when water is exposed to a low temperature for over a period of time, it freezes and turns to ice.

Changing its form from liquid to solid state by causing the temperature to increase. Similarly, when we expose water to excessive heat, it turns into vapor, shifting from liquid to gas. Thus, we can say that temperature causes it.

Force

Sometimes we are able to change the form of an object by applying a certain degree of force to it. One of the best examples of this will be when a sculptor carves out a statue from a rock. He applies force to the rock with chisel and hammer causing the rock to take shape of a statue.

Similarly, a goldsmith uses force on the lump of gold to flatten it out and then create intricate jewellery out of it. Therefore we can say that force can bring a change.

Chemical Mixing

Some changes occur when you mix two chemicals together. For instance when you mix two chemical salts to create a new chemical salt, thereby changing its composition. Like when we mix one molecule of sodium to one molecule of chloride, we get sodium chloride which is the chemical term for common salt.

Similarly, when we mix two molecules of hydrogen with one molecule of oxygen, we get hydrogen dioxide, which is the chemical term for water. Hence we can conclude that chemical mixtures can also cause it.

Answer 2

The following are the different ways to bring about changes:

Explanation:

• Change in temperature: The change in temperature can be caused by raising the temperature or reducing the temperature. When the temperature of the water is reduced then water will transform into ice whereas when the temperature of the water is increased the liquid water can changed into vapor form.
• Application of force: A shape of an object can be changed by applying a certain degree of force on it. For example a force applied with the help of hammer on the rock can cause rock to break apart.
• Chemical mixing: When one or more chemicals are mix together they will result in development of new product or chemical. This is a kind of chemical change in the reactant chemicals.
