Why is there a white triangle under the space shuttle engines when they are lit?
Why is there a white triangle under the space shuttle engines when they are lit? Within the flame produced by a lit space shuttle engine, there are temperature and pressure differences causing the flame to appear in different colors. The white triagle is made the by the shape of the space shuttle engine in combination with these temperature and pressure differences.
What would happen if you tried to light a match on mars?
There would be no flame because fire needs oxygen to burn, and the Martian atmosphere consists mainly of Carbon Dioxide.
What causes the moon to appear in different shapes at different times?
The direction is is lit from. When the Moon is lit (by the Sun) from straight on it appears full, when it is lit from behind it appears new, and when it is lit from the side it looks like a semi-circle.
What happens when you hold a spiral paper over a lit candle?
When you hold a spiral paper over a lit candle, the heat causes the air within the spiral to rise, creating a mini updraft that makes the spiral rotate. The rotation is caused by the temperature difference between the inside and outside of the spiral paper.
What happens when a match is lit?
Matches contain sulfur, glass powder, and an oxidizing agent as the components in the match head. When you strike a match, the friction due to the particles of glass powder rubbing together generates enough heat to convert some of the red phosphorous to white phosphorous, which burns in the presence of oxygen gas. The heat from the friction also causes the oxidizing agent to produce oxygen gas, igniting the small amount of white phosphorous. Once ignited, the oxygen gas fuels the flame while the rest of the sulfur catches on fire. Of course, this entire process happens in a fraction of a second. At this point, the entire match head is on fire, so the oxygen in the air keeps the flame going while the rest of the match burns.
What energy conversion occurs when a match is lit?
When a match is lit, chemical energy stored in the match head is converted to thermal energy through a chemical reaction called combustion. This thermal energy raises the temperature of the match head, causing it to ignite and release light and heat energy in the form of a flame.
How many forms of energy in a lit match?
A lit match contains chemical energy stored in the match head, as well as thermal energy released as heat and light when the match is burning. So there are at least two forms of energy in a lit match.
In the little match girl what happy vision did she see every time she struck a match?
When she lit the first match, she had a vision of a large polished iron stove, giving of a delightful warmth. When she lit the second match, she saw a roast goose on a dinner table. When she lit the third match, she had a vision of sitting under a beautiful Christmas tree. Every match she lit after that gave her a vision of her beloved dead grandmother, who finally took the little girl up to heaven.

Had only one match and entered a COLD and DARK room?
The match wasn't lit.
Which of these is an example of a time switch?
A fuse lit with a match
Is a lit match kinetic or potential energy?
A lit match has both kinetic and potential energy. The potential energy is stored in the chemical bonds of the match head before it is lit, and the kinetic energy is released as heat and light energy when the match is ignited.
What will lit matches in a bottle produce?
If you put a lit match in a bottle, and put like a screw cap on it, the flame from the match will use up all the oxygen in the bottle and when there is no oxygen left, the match will just go out.
How do you make fire faster?
Lit a wood with a burning match
What is an example activation energy?
holding a lit match to paper
What type of energy is a match before it is lit?
chemical energy
How much energy is in a match head?
Technically its potential energy until it's lit, and then it depends on the match brand.
