Why does dull dark objects emit more heat than bright shiny ones?
Dark objects absorb heat, while bright shiny ones reflect heat back.
Do all objects equally conduct absorb or emit heat?
No, not equallyNo. There's a lot of variation.
What are objects that emit light?
Objects that emit light are usually referred to as incandescent.
What are the five sources of light and heat?
1. The main source is the sun. Even though rocks seem like they emit heat, they really got their heat initially from the sun. 2. Radioactive substances emit their own energy and heat. 3. Warmblooded animals emit heat. However, they make the energy from the food they eat which ultimately came from the sun. 4. Electricity. Electricity can be used to make heat and light. 5. Other stars from other solar systems emit their own light.
What elements that emit atomic particles are called?
radioactive elements

What type of energy do warm objects emit and which has a longer wavelength than visible light?
heat/IR
What are isotopes considered radioactive?
Not all isotopes are radioactive; the radioactive isotopes are unstable and emit radiations.

What are atoms that emit particles and energy from their nuclei?
radioactive
Do all objects radiate energy?
yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in. yes. as long at the obj is above absolute 0, it has energy and hence will emit heat. whether there is a net heat gain or loss depends on the environment it is in.
How is radioactive Isotope different from a stable isotope?
The radioactive isotope is disintegrated in time and emit radiations.

How is californium radioactive?
Californium emit alpha particles and neutrons.
