What is is called when light reflects off from an object?
An Object which reflects light is called an illuminous object. e.g) The Moon: Reflects off sunlight
What is given off when energy is lost in an environment?
Heat.
What form of energy is given off by a flashlight?
A flashlight is given off light and heat energy once turn on.
Which absorbs heat which gives of heat?
Any object which is cooler than its surroundings absorbs heat and any that is warmer, gives off heat.
How is heat transferred between 2 objects that are not touching each other?
You can do this by the 3 ways of transferring heat. Conduction, Radiation, and Convection. You can use conduction by putting something between the 2 objects, and then the thing between will heat up depending on the temperature of the object, and the other object will heat up as well. You can use radiation by using waves. That is how the sun heats the Earth up. It sends waves that get trapped inside earth's atmosphere and get absorbed into the ground and given off by heat. That last way is through convection. An example of this is steam. It is given off by a boiling liquid and is hot.
What is it called when heat causes an object to give off light?
energy
What is it called when heat diffuses off an object into the surrounding air?
Thermal radiation is when heat diffuses off hot surfaces
Heat given off or absorbed in a reaction is called?
Enthalpy
Light and heat given off by the sun is called?
Solar Engery
A change of state where energy is given off is called a blank change?
The process in which energy is given off is called an exothermic change. The energy released can be in the form of heat, light, electricity, or sound
What is exothermic heat?
It is Heat that is 'given off' by a chemical reaction.
A chemical reaction that invoves heat given off is called what?
exothermic (or exergonic if discussing energy being released in any form, including heat)
Why do some reactions keep going?
They are what is called exothermic - give off heat. If a reaction is caused by applying heat, any heat given off can chain react and cause more reaction - more exothermic action.
What is the term for extra heat given off by machines?
Waste heat
Heat is given off when striking a match?
The friction creates the heat.
What is light and heat given off by sun?
The light and heat given off by the sun are actually high energy produced by nuclear fusion of hydrogen.
