States of matter

Changes in the states of matter


Matter is anyting that have mass and take up space. matter divides into three kinds of states. Solid, liquid,and gases. the solids particles are compact, they not move freely such as liquids particles, and gases particles are  more separated .
The three kinds of states change by especifics conditions like heat or by decreases temperatures.


A solid became into liquid when this is subjected to increases temperatures. The solids have a melting point that. When the solid reaches this point the particles started to move freely.
The heat required to melt 1 kg at its melting point is called heat of fusion. This is the change from solid to liquid, but it can be also upside down. 

The liquid can be changed into solid when this reaches a decrease temperature the temperature at which this occurs is called the frezzing point. There are materials such as glasses in which this converts more vicous as its temperature decreases.

When you are baking a bread                                                              Are exothermic reactions because the heat is transferring to the                                                               in all the points heat is been  bread, so, this is absorbing

Skill Builder CONCLUSION :   My conclusion about this experiment is that the number of swings varies by the long of the string. If the string is short it will be do more swings per minute than if it is longer

SOURCE FOR HEAT ENERGY SOURCE:  I select a solar collector beacuse is a system that is starting to be using. CONCLUSION:  collector area  =400 ft2   = 1  living space = 1,076 ft2    = 2.69 For each 2.69 ft2 of living space of my home, we will need 1 ft2of solar collector, for keep the heat at the home.
