It depends on:
1. Type of gas and its calorific value,
2. Volume of gas per minute/second,
3. Oxidiser and completeness of combustion.
The blue flame is really hotter than the yellow flame. If you put your hand over a blue flame and skim through it, it would burn you but if you put it over a yellow flame it wouldn't burn you that much.
Expand the air inside it......Put a flame to it and it will pop...
it means never put an open flame in your pocket because if you do then youl probly die. And holding grudges are bad
You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. You boil some water and put the test tube in and its heated up but you don't have to worry about a flame. To heat a test tube you simply use a Bunsen burner. Make sure you use pliers to hold it with though because it will get very hot. Also you can change the heat of the Bunsen burner by switching it to the blue flame. you always hold it away from you and your lab partner. heat it sideways and slowly run it through the flame to distribute the heat evenly.
A Bunsen burner produces heat and creates a heat source when doing an experiment. It uses methane and there is two flames a safety flame-you can put your hand through it without burning your hand and a roaring flame-this flame is blue and it is what you use when you preform an experiment.
The heat from the burning candle causes the air around it to warm up. When you place your hand above the flame, you are feeling the heat radiating from the flame onto your hand. This sensation is your skin detecting the higher temperature of the air near the flame.
When you put water in a balloon and place it over a lit candle, the water in the balloon absorbs and distributes the heat from the flame, preventing the balloon from bursting. The water acts as a heat sink, keeping the balloon cool enough to withstand the heat from the candle without melting or bursting.
When you place your hand above the lighted candle, you are closer to the source of heat, which is the flame. The heat rises vertically from the flame and directly impacts your hand when placed above it. On the other hand, when your hand is at the sides of the candle, you are farther away from the direct source of heat, so you feel less heat.
If you put your finger above a candle, you may feel the heat radiating from the flame and might sense some discomfort or pain if you hold your finger there for too long due to the heat. However, you won't typically get burned unless you touch the actual flame itself.
If the bottle is from glass will burst soon; the plastic container will be melted.
When hydrogen is introduced to a flame, it burns with a pale blue flame that is almost invisible in daylight. The flame produces a lot of heat but relatively little light. Burning hydrogen produces water vapor as a byproduct, making it a clean fuel source.
No, not at all. There can be heat without flame. Something can smolder and put out more smoke than something that is at a rolling fire.
