What type of reaction absorbs thermal energy?
Endothermic reactions are reactions which absorb heat rather than exothermic reactions which emit heat. Consider the example of carbonated water, as it has CO2 dissolved it's in form of carbonic acid and it splits. H2CO3 -> H2O + CO2 In this reaction heat is absorbed.
Does freezing lose heat or add heat?
Endothermic reactions absorb heat, while exothermic reactions emit heat. Both can be used to generate freezing depending on various chemical compounds.
Can black holes emit radiation?
Yes it is theorized that black holes constantly emit radiation in the form of thermal energy (Heat) also called Hawking radiation and black-body radiation.
Does it take more heat to heat water or to boil water?
It takes more heat to boil water than to simply heat water. Unless the water is already at its boiling point.
Can an object containing heat emit x rays?
Thermal energy is nearly the same thing has heat. The distinction has some linguistic aspects. If I add heat to an object, I increase its thermal energy. Anything that contains thermal energy contains heat or heat energy. The words "heat energy" and "thermal energy" are used interchangeably. The word heat has other flexible uses. It can be a verb. Outside of science, the terms heat and temperature are use to mean the same thing, but this is technically wrong in scientific usage.
Why Silicon and germanium emit light?
they emit heat when their is a recombination of electron and holes
Do electric cars emit heat energy?
Yes. The electric motor does emit some heat. Also, when the car is stopping, forward energy is converted into heat.
Do polar bears emit heat?
yes
What type pf heat does uranium emit?
Uranium don't emit directly heat; under nuclear fission the kinetic energy released and the energy of radiations is converted to heat and after to electricity.
What mass of natural gas CH4 must you burn to emit 267 kJ of heat?
5.33g CH4 must be burned to emit 267 kJ of heat.
What type of radiator of energy is an object that is a good absorber of radiation?
An object that absorbs heat well will also emit heat well. The object will emit heat until equilibrium is reached with its surroundings.
What do stars emit besides heat and light?
They emit: gamma rays, radio waves, and x-rays. Some stars emit T.V. rays
Why is the back of a fridge painted black?
To emit heat
What does a white light bulb emit?
light and heat
What should be used to remove heated to heated objects?
When a substance is heated up, it emit heat radiation. In such way substance keep on losing heat energy. Thus a way that increase heat losing can lower heat of substance. Water can used as heat absorber.
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 heat transfer method do all abjects emit?
