God's energy, glory and law order produced heaven and earth. Matter was created. Matter has different "states". But always remember that God is the "Source" and the "heavy weight". He is the energy that created and defined the weight of matter and everything else.
With that said let's start today's lessons found at BBC Schools:
Changing State:
1. States of matter
- Nearly everything exists as solids, liquids or gases. Solids, liquids and gases are called the three states of matter.
- Materials can be changed from one state to another by heating or cooling.
- If ice (solid) is heated, it changes to water (liquid). This change is called melting.
- If water (liquid) is heated, it changes to water vapour (gas). This change is called evaporation.
- If water vapour (gas) is cooled, it changes to water (liquid). This change is called condensing.
- If water (liquid) is cooled, it changes to ice (solid). This change is called freezing.
2. The water cycle
Water on the earth is constantly moving. It is recycled over and over again. This recycling process is called the water cycle.
a. Water evaporates into the air
The sun heats up water on land, and in rivers, lakes and seas and turns it into water vapour. The water vapour rises into the air.
b. Water vapour condenses into clouds
Water vapour in the air cools down and changes back into tiny drops of liquid water, forming clouds.
c. Water falls as rain
The clouds get heavy and water falls back to the earth in the form of rain or snow.
d. Water returns to the sea
Rain water runs over the land and collects in lakes or rivers, which take it back to the sea. The cycle starts all over again.
E = mc 2 :
Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist. He is best known for his theory of relativity and specifically mass–energy equivalence, E = mc 2.
