Heat and Temperature

Heat & Temperature

Heat is the transfer of energy from one part of a substance to another, or from one body to another because of a difference in temperature. Heat always flows from a substance at a higher temperature to the substance at a lower temperature, raising the temperature of the latter and lowering that of the former substance, provided the volume of the bodies remains constant.

Temperature vs. Heat
Grade: 3 - 9
The lesson explains that heat refers to quantity of hotness, and is determined by the mass and speed of molecules. It demonstrates that a bucket of water at a temperature of 50C contains more heat than a cup of water at 100C.

Temperature and Heat: A Discussion
Grade: 3 - 9
A presentation on temperature and heat.

Measuring Temperature
Grade: 3 - 9
Learn how Swedish scientist Anders Celsius invented the Celsius thermometer, using the expansion of mercury as a measure of temperature.

Different Temperature Scales
Grade: 3 - 9
The lesson discusses the different temperature scales, and conversion from Celsius to Fahrenheit and vice versa.

Fahrenheit to Celsius Conversion
Grade: 3 - 9
A chemistry tutorial on converting from Fahrenheit to Celsius.

Celsius to Fahrenheit Conversion
Grade: 3 - 9
A chemistry tutorial on converting from Celsius to Fahrenheit.

Heat as Energy
Grade: 3 - 9
The lesson explains that whenever there is movement and friction between two objects, heat is produced. Since movement is a form of energy, it follows that heat must also be a form of energy.

Radiation Waves
Grade: 3 - 9
The lesson explains that one of the main ways in which heat energy moves is in the form of waves. This kind of heat transfer is called radiation.

Radiation Spectrum
Grade: 3 - 9
The lesson explains that the waves of heat energy radiated by the Sun come in many forms, which together make a band, or spectrum, of energy waves.

Video on Conduction
Grade: 3 - 9
Introduces the concept of conduction, explaining that the application of heat to an object makes the molecules or atoms vibrate faster and causes a 'domino effect' that carries heat energy across the object.

Video on Convection
Grade: 3 - 9
Introduces the concept of convection, explaining how the principle of buoyancy is responsible for the process of heat transfer called convection.

Heat Transfer Demo - Conduction, Convection and Radiation
Grade: 3 - 9
The presentation demonstrates three experiments about heat conductivity.

Which is the Better Insulator?
Grade: 3 - 9
Learn about insulators with an experiment. Cups full of water are placed into bowls of liquid nitrogen. Find out which cup insulates the best?

Melting Point of Metals
Grade: 3 - 9
A presentation about melting point of various metals.

The Race for Absolute Zero
Grade: 3 - 9
A physicist explains how matter changes as it is reduced in temperature and nears absolute zero (-459.67 F or -213.15 C). Absolute zero is the coldest possible temperature, and at that temperature no heat energy remains in the matter.
