Thermal Energy and Heat
· Temperature is a measure of the average kinetic energy of each particle within an object.
· Three temperature scales are Fahrenheit, Celsius, and Kelvin
· Thermal energy is the total energy of the particles that make up an object
· Temperature – The measure of the average kinetic energy of the particles in a substance.
· Fahrenheit scale – The temperature scale on which 32 and 212 are the temperatures at which water freezes and boils.
· Celsius scale - The temperature scale on which zero and 100 are the temperatures at which water freezes and boils.
· Kelvin scale - The temperature scale on which zero is the temperature at which no more energy can be removed from matter.
· Absolute zero – The temperature at which no more energy can be removed from matter.
The nature of heat
· Heat is a transfer of thermal energy from an object at a higher temperature to an object at a lower temperature.
· Heat is transferred by conduction, convection, and radiation.
· A conductor transfers heat well whereas an insulator does not.
· The amount of heat necessary to raise a given mass of a substance by a specific unit of temperature is called the specific heat.
· Heat – Thermal energy that is transferred from one substance to another.
