What are some examples of radiation in the food you eat?
A hot food item emits heat that you feel when you burn your tongue, and the heat transferred thusly is mostly transferred from the hot food item to your tongue through the process of conduction. However, had you paid attention to the 'thermal radiation' of the food item, you'd not have burned your tongue in the first place.

How do you do a conductivity test?
It depends on what kind of energy you want to see if the item will conduct. Example: We want to see if our unknown item will conduct heat. The first thing we do is find out if this item has any undesirable properties like flammability. If it doesn't we'll attach a thermometer to the top, heat up the bottom and find out how fast the item rises in temperature.

Asked in Science
Four differences between heat and temperature?
Heat is the amount of total energy contained within an item; both potential energy and kinetic energy. Potential energy is stored energy and kinetic energy is moving energy. Temperature is a number that corresponds to the amount of kinetic energy in an object. When heat is introduced into a system, molecules move faster. When molecules move faster, they bump into each other harder and more often. These measure of the energy of these collisions is temperature. So, temperature can result from heat being introduced into an object; that is, heat is energy introduced into a system and one affect heat can have is to increase the temperature. Heat introduced into a system can also cause a phase change; like ice melting into water, with no subesquent speeding up of molecules, and therefore no temperature change. In summary, heat is energy introduced into a system and is a measure of all the energy in an object. Temperature is proportional to the amount of kinetic energy an object has.

Asked in Chemistry
What is a small item which transforms chemical energy to heat and light to start burning reactions?
What is heat made off?
Heat is often referred to as thermal energy. A body, item, or system is said to have more heat when its temperature is high. Temperature refers simply to how fast an items molecules are moving. So as an object increases in temperature, its amount of heat or thermal energy, goes up. Thus, heat is not a specific thing inandof itself, but more of a property.
