How does the sun ceate heat and light?
sun creates heat because it is a burning star and the brightness of the flames give us light
What keeps a star on the main sequence from collapsing?
Nuclear fusion produces heat, and heat creates the pressure which keeps the star from collapsing under its own gravity. The relationship between heat and pressure in a gas is described by the Ideal Gas Laws. It also applies to plasma (which can be described as a super heated gas).
What is the color of the hottest star and why?
The hottest star is of blue color. The more the heat , the more is the excitement of electrons in star. This electrons vibrate with high frequency and emits light. Since the frequency is high, it appears as of blue color
What creates the heat while a space shuttle is leaving the atmosphere?
In the exosphere, Friction between the atmosphere and the shuttle creates the heat.
Why does a spacecraft need a heat shield to return to earth?
The speed of reentry combined with air friction creates a massive amount of heat at the point of entry. Heat shielding allows the craft to survive the high temperatures intact, but even a small defect in shielding can be catastrophic.
What creates the heat and light in a star?
Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.Nuclear fusion, in the star's core.
Why are there no spark plugs on a compression ignition engine?
They are not needed, the high compression creates enough heat for the air fuel mixture to self ignite.They are not needed, the high compression creates enough heat for the air fuel mixture to self ignite.
How high can Lyra the star heat up?
Lyra is a constellation not a star
When does a star die?
it dies when it drifts away from the sun and its heat is realeased and creates a black hole
How does the sun ceate heat and light?

What do we call an object that produces its own heat and light energy?
the sun creates it's on heat because it already fire
What are some devices that are wired such that they have a high resistance in order to create heat?
A light bulb is the best example. The tungsten creates such a high resistance that all the accumulated heat produces light energy.
In ultrasonic welding what creates the heat required for welding?
What creates the heat is the flame inside the torch
What ia an abundant polar covalent molecule that serves as a solvent has a high heat capacity creates a high surface tension and serves as a lubricant?
H2O

What system creates most body heat?
The system that creates the most body heat is an exothermic system. These systems are known for expelling excess heat.
What is the color of the hottest star and why?
