Why a gauze is often placed over a burning flame for heating an object?
To prevent flame impingement on the vessel being heated, which could damage the vessel. A flame cannot pass through a gauze (or screen). as a proof you could set up a bunsen burner beneath a wire gauze. Turn the gas on and ignite the gas above the gauze. you will notice the flame will stay above the gauze. If you ignite the flame beneath the gauze and lower the gauze into the flame, the flame will not pass above the gauze. Yet, if you light both below and above the gauze you will have flame on both sides. Indicating that flames impinging on the gauze do not burn the gas completely and the gas will pass through the gauze.
When Bunsen gauze gets hot what do you see?
To answer this question, you need to understand how heat conduction and combustion work. Here is a possible answer: When Bunsen gauze gets hot, you see different effects depending on where you light the gas. If you light the gas below the gauze, the flame will only appear at the bottom, but not above the gauze. This is because the gauze is a good conductor of heat, and it takes away the thermal energy that would otherwise ignite the gas above the gauze. If you light the gas above the gauze, the opposite happens. The flame will only appear at the top, but not below the gauze. This is because the gauze also prevents the hot gas from mixing with the cold gas below, which is necessary for combustion. In some cases, you might be able to lift the flame up with the gauze, if you do it very slowly. This is because the gauze becomes hot enough to ignite the gas above it, and the flame follows the heat source. However, this is not a reliable or safe method, and it should only be done as a demonstration by a teacher.
What are the energy change when a wire gauze is heated wityh a bunsun burner?
Natural Gas, CH4, is rapidly oxidized producing heat, CO2 and water. The heat is absorbed by the wire gauze and surrounding atmosphere.
What sits on a tripod to spread the heat of a Bunsen burner?
When heating beakers, a ring or square of wire gauze is placed on top of the tripod over the burner. The gauze may incorporate an asbestos pad or coating. The wire spreads the heat to prevent overheating of one part of the beaker.
What is the relation between pressure in atmosphere and pressure?
Atmospheric pressure is the surrounding pressure around us. We live in the atmosphere and treat the atmospheric pressure as the base pressure. A pressure gauge would read 0 at atmospheric pressure. When we define the pressure in scientific way of absolute pressure, we need to add up an atmospheric pressure to the measured pressure.
