Is fire invisible?
Fire is not invisible; fire is the chemical chain reaction from combustion that creates heat and light. Combustion, which is the actual burning process, is strictly chemical rearrangement and is invisible - but once you add oxygen to it, it becomes visible as fire.
If you add too much air to a fire in a Bunsen burner the fire cools or is blown out but what happens during the time the fire cools?
The fire doesn't actually "cool". Fire needs 4 things to occur, known as the fire tetrahedron. It needs fuel, oxygen, heat, and a sustained chemical reaction between the three. If too much "air" is added, you are basically robbing the fire of it's fuel source because the ratios are off due to the air/fuel ratio. It becomes to lean to burn any longer. As the flame on the burner becomes robbed of the oxygen it needs and becomes leaner, it begins to produce less btu's, the measure of heat.
Is the taal volcano part of the ring of fire?
No. It is a hot spot volcano over a mantle plume.
Why does a room with a gas fire need to be ventilated?
First warm/hot air is lighter than cool/cold air. As the fire in the fireplace consumes oxygen from the surrounding air, it is also heating this air. This heated air then rises, and as it rises cooler air is drawn in from the surrounding room. As long as the air in the fireplace is warmer than the air in the room, this process will continue..
Why would an element change color when on fire?
As anything is heated it also looses heat back to its surroundings by radiation. The wavelength of that radiated energy is related to temperature. As temperature rises, the radiation becomes of increasingly higher energy, higher energy radiation means decreasing wavelength. At low temperatures, the radiation is IR - infra-red, which we cannot see. As temperature rises, the radiation becomes red, then orange light. Keep heating and eventually the light will become white as light of increasingly higher energy (shorter wavelegth) is emitted. Eventually you have a lamp (light bulb) element (if it hasn't melted or chemically reacted long before that point).

What can happen when a fire becomes unstable?
When fire becomes unstable, it becomes disastrous. It is difficult to handle it.

Why does smoke from a fireplace go up the chimney instead of out into the living room?
Hot air always rises. Therefore, when a fire is started in a fire place, the hot air from the fire rises, causing the smoke to rise also.
As regards large fires involving hazardous materials what is plume modeling why would it be done and who would do it?
Plume modeling is a computational technique used to predict the downwind concentrations of pollutants resulting from a fire or spill of chemicals. It is used to advise the Fire and Emergency services about areas (and people) at risk from the pollutants and to allow the decision about whether to evacuate the "at risk" people or to advise them to "shelter-in-place" in homes or workplaces. Plume modeling is best done by trained personnel such as scientific officers attached to the Fire and Emergency services or the EPA.

Why does fire always point up?
Heat rises to colder areas.
When do convection currents form?
Convection currents can form any time at any place, even in your stove or house. It is created when a warm fluid rises and moves, becomes cold, falls, and is heated up again. it is a cycle see!! For example, pretend you are boiling water. The fire heats up the water at the bottom, the water rises than cools when it is on the fire and is not being heated. So the cold water falls again and later heats up due to the fire. Oh yeah, warm fluid has less density, so it rises, cold fluids have a greater density, so it falls.
Why does the Hot air balloon rise when the fire is lit beneath the balloon?
The fire warms up the air and the air becomes less dense. So the balloon traps the warm air and since less dense gases rise with denser gasses around it, the warm air rises taking the balloon with it.
Why is air fresher near the ground in a fire?
because hot air rises
