Why does the sun emit heat and light?
The heat and light emitted from the sun comes from the nuclear reactions that occur on it.
What emits light with heat?
The Sun does this, of course.
What process cause stars to give off heat and light?
what causes stars to give off heat and light is when the poporazzi abushes them and they get really mad...that would be the heat. and the flashes form the cameras would be the light
How does the sun ceate heat and light?
sun creates heat because it is a burning star and the brightness of the flames give us light
What two things does the sun give off?
heat and light
Do chemical reactions give out energy in the form of heat light or sound?
all 3
Do most of the chemical reactions that give off light also produce heat?
Yes.
What is a chemical reaction producing heat and light?
Any chemical will give off light if it is heated to a sufficiently high temperature. There are also chemicals that give off light at relatively low temperatures. Fireflys produce a type of chemical called luciferins, that produce light.
What reactions produce light and heat?
Burning.
Do all acid reactions give off heat?
No, endothermic reactions absorb heat. Exothermic gives off heat.
Differentiate exothermic from endothermic reactions?
Exothermic reactions give out heat; Endothermic ones absorb heat.
What chemicals reactions give out heat?
Exothermic
Why does the sun emit heat and light?
The heat and light emitted from the sun comes from the nuclear reactions that occur on it.
What chemical reactions can give off heat or what?
These chemical reactions are named exothermic.
What chemicals reactions give out heat which involves change color?
These are exothermic reactions.
Do chemical reactions often give out heat?
yes
What do chemical changes always take in or give off?
Some reactions give off heat (exothermic), others absorb heat (endothermic). All reactions increase entropy.
