How is thermal energy transferred?

 

CONDUCTION: when two objects are in contact thermal energy is transferred from one object to the                              other.
CONVECTION: thermal energy travels through a gas or a liquid by convection. Molecules move in                                a circular way.
RADIATION: thermal energy can be transferred through space.

Here are some videos about heat transmission

The economy and the three sectors of the economy

WHAT IS THE ECONOMY?

The economy is the system of using resources, buying and selling.

It is divided into three sectors:
       
         - Primary sector: provides raw materials from nature.
        - Secondary sector: uses raw materials to produce manufactured products.
        - Tertiary sector: provides services.

WHAT TO STUDY FOR YOUR SCIENCE EXAM - ENERGY


-         WHAT IS ENERGY: Energy is the ability to do work. The ability to move, heat up or produce light. Pages 4 and 5.

-         FORMS OF ENERGY:  mechanical (kinetic and potencial), chemical, thermal, light , electrical  and nuclear.. Definitions and examples .
     Pages 6, 7 and 8.

-         CONSERVATION LAW OF ENERGY: Energy can not be created or destroyed, but it can be transformed and it can be transfered from one object to another. Pages 10 and 11.

-       Examples of energy transformations. Eg. Potential energy changes into kinetic in a rollercoaster.
-   
      Pages 12, 13, 14 and 15 NO
