Regarding the Change in the Form of Substances by Heat
In physics every thing that has a mass and occupies a space is called a substance. And if that has no mass but occupies space, then it belongs to an energy. Which includes those that have no mass such as sound and light. So, in physics that actually concerns the matter of matter and energy. But this time it was discussed about the problem of the substance's form and its changes, the shape of the substance can change due to the heat given or released.
Substance Change
In physics the basic theory of matter is divided into 3 forms, namely:
Solid
Liquid
And gas substances
In science physics, the basic theory of matter explains that matter can undergo a change in form. In solid substances that can change their form into liquid this is usually called melting. Among these, like chunks, ice can turn into water. Then the water can be turned into steam which is called the evaporating event. Which includes events such as the evaporation of water on the surface of the earth into water vapor in the clouds. The opposite of changing the form above is to condense and freeze. The occurrence of water vapor conditions in the sky can experience the occurrence of this condensation because of the presence of dew that is attached / attached to any object or plant in the morning.
There is also an event of change in form which does not undergo a process of melting but instead directly becomes steam, this event is called by flooding such as mothballs turning directly into steam. The reverse process is called crystallizing in which camphor lime can transform into a camphor crystal.
Effect of Heat Against Substance
Heat can increase the temperature of a substance that affects the change in the form of a substance. Melting and evaporating which is an event that requires heat, because to be able to melt a lump of ice or to evaporate water requires heat.
But the event of condensation and freezing does not require heat but releases it, the occurrence of dew forming in the morning is an example of the change in form that releases heat. Likewise the freezing event will release a number of heat so that the water freezes to form a lump of ice.
Like a refrigerator (refrigerator) is the application of the occurrence of changes in the form of liquid substances that become solid, a tool functioned to remove the heat in the water. So thus chunks of ice can form in the refrigerator because the heat in the water has been removed by the device.
So it can be concluded that the substance that changes the substance is caused by the heat, in such a process the heat is needed by the substance to change its form, but some do not need the heat alias released.
Thus the language about the matter of Substance Changes by Kalor hopefully with the review can add insight and knowledge, thank you very much for visiting
