What occurs when energy is added or taken away?
When energy is added,solid will melt into liquid or liquid will change into gas. (When energy is added it gains heat).When energy is removed, the liquid will turn into solid or the gas will turn into liquid. (When energy is removed the heat will lose).
What is the difference between red and blue flame?
Difference is the excitation and ionization energy of atoms in the flame, likely fuel atoms, such as propane, and atmospheric atoms, such as oxygen, argon, hydrogen, nitrogen, etc. In the blue flame, the energy released by the atoms in the flame is more energetic. This is because blue light is of higher energy than red light. Blue light is lower wavelength, higher frequency, and higher energy than red light. The reverse is true in the red flame, the atoms are not releasing as much energy because red light is of lower energy. When an atom enters the flame, it absorbs energy thus exciting electrons to higher energy levels (higher than ground state). At this point, the excited atom can simply release this energy as visible or non visible light--and often relax by non-radiative means. Or the atom can lose an electron because the energy absorbed was so high and continue to excite other electrons to other levels and possibly remove a second or third electrons if the flame was energetic enough. In a flame, usually only first ionization and excitation occur. After these electrons are excited to whatever level, they have to release energy. Often, these atoms release this energy, if the energy level correlates, in the form of visible light. Other times, the light is released in non-visible portions of the electromagnetic spectrum. The light emitted from a flame is a measure of the energy available in the flame. With a given gas etc. distributions of atoms in excited states can be calculated, after spectra are collected, with the Boltzman equation and for ionization calculations one can use the Saha equation.
The change of water from a gas to a liquid?
The process of changing liquid water into a gas is called evaporation. Energy is added to the liquid water - generally in the form of heat. When enough energy is added, it allows the most energetic molecules at the surface of the liquid to break free of the liquid and enter the gas phase. The more energy that is added, the more water molecules will have enough energy to move into the gas phase. If enough energy is added, all the molecules will leave the liquid and from then on adding energy will just make the gas warmer. Another way to change liquid water into gas is to drop the pressure above the liquid. In this case, it takes less energy for the molecules in the liquid to get away from the liquid so some of them will already be energetic enough to get away. Any mass of liquid water will have a range of energies for the molecules, some will be low energy, others high energy with each collision between the molecules, they either gain or loose energy. If they gain enough energy, they can become energetic enough to escape the liquid as a gas. The higher the pressure, the more energy is required to become a gas. If the liquid water is in contact with some gas - air for example. The liquid will evaporate until the gas is saturated with water vapor. At that point the rate of water molecules dropping out of the gas back into the water (because they don't have enough energy to stay in the gas) is equal to the rate of water molecules escaping from the liquid to become gas. This point is also known as "equilibrium".
You use mechanical energy to walk around what form did this energy have before your body changed it into mechanical energy?
Chemical energy ... in food ... which plants made from solar energy, water, and dirt.
Describe the role of energy when ice melts and when vapor condences to form liquid water?
When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
When Energy is added in the form of heat to a pot of water on the stove what would happen to the water?
increase kinetic energy.
How does a bubble form when you heat water?
When water is heated, energy is being added to it, this causes it to change form a liquid to a gas
What must be true for water to change temperture?
Energy in the form of heat must be added to the water.
Why flame is observed during the burning of a substance?
During combustion, energy is released. Some of this energy takes the form of light, making the flame visible.
What happens to potassium when it is added to water?
Solid, pure, potassium metal will react violently with water to form hydrogen gas. Often this hydrogen gas will ignite causing a flame and sometimes an explosion.
Chemical energy is energy that is?
added to a reaction in the form of heat.
What state of matter is a flame considered as?
A flame is not a substance like water or air. Rather, it is the result of heat and light energy so you can't really say what state of matter it is in. Think of it like this; asking what state of matter a flame is in would be like asking what state of matter light or heat are in. They are forms of energy, not substances.
Does a flame give off oxygen?
No. A flame is usually the result of oxidation, meaning oxygen combines with another element or molecule creating a new molecule, giving of energy in the process. This energy in the form of heat and light is the flame.
What form of energy was form in a bathroom shower?
water energy

Is water a form of electromagnetic energy?
Water is matter. Electromagnetic energy is energy in the form of electric fields and magnetic fields.
