WEEK 1: THERMAL ENERGY.
Energy the mainspring of all of life and of all activities of mankind.
Thermal energy or heat energy is a form of energy. It is a form of energy which tends to move from one place to another, especially from its source to cooler areas. It thus a spontaneous flow of energy from one object to another, caused by difference in temperature between two objects.
Thermal energy is the energy that comes from heat. This heat is generated by the movement of tiny particles within an object. The faster these particles move, the more heat is generated. Stoves and matches are examples of objects that conduct thermal energy.
Interesting Thermal Energy Facts:
Thermal energy is a part of the total energy of any object.
Thermal energy is related to the temperature of an object.
The joule is the unit used to measure thermal energy.
Unlike other forms of energy, thermal energy is difficult to convert to other forms of energy.
When thermal energy is transferred from or to an object, it is called heat.
Since heat is known as a process, objects cannot contain heat. Objects contain thermal energy.
In order to convert thermal energy into other forms of energy, a machine such as an engine is needed.
Unlike other forms of energy, the amount of thermal energy is not dependent upon the amount of work an object performs.
As heat from Earth is lost to space, it is replaced by heat brought by the Sun.
Although he was not the first to use the term thermal energy, James Joule receives credit for being the first to discuss the loss and gain of heat.
When you add ice to a warm drink, some of the drinks’ thermal energy is transferred to the ice which makes the drink cooler.
Heat and temperature are not the same thing because temperature is related to how hot or cold something is.
Heat energy can be transferred by three ways: convection, conduction, and radiation.
Conductors, such as metals, are objects that allow thermal energy to move easily through them.
Insulators, such as plastic, are objects that do not allow thermal energy to easily move through them.
EVALUATION:
1.Write another name for Thermal
2.mention ten metals around you.
