What else can I help you with?
Out of carbon helium hydrogen oxygen and uranium which is the main source of the suns energy?
Hydrogen The sun is just made up of Hydrogen 74.9% and Helium 23.8%. The suns high pressure, and temperature fuses hydrogen into helium. The process is called Nuclear Fusion, this releases a lot of energy.
Why must a star convert helium after it has converted all of its hydrogen to helium?
As a star exhausts its hydrogen fuel and increases in temperature and pressure, it needs to start fusing helium to produce energy and maintain equilibrium against the inward force of gravity. This process is necessary to sustain the star's energy output and prevent collapse.
How does helium help space shuttles get into space?
Helium is used as a pressurizing agent in the fuel and oxidizer tanks of space shuttles. By regulating pressure during fuel consumption, helium ensures a steady flow of propellants to the engines, which is crucial for achieving the necessary thrust to lift the shuttle off the ground and into space.
What happens when a balloon filled with helium goes into space?
In space, the helium inside the balloon will expand due to the absence of atmospheric pressure. Eventually, the balloon will burst when the pressure inside it becomes greater than the tensile strength of the balloon material.
Why did the helium flash cause the core to expand?
Well, it's like bringing colors to the canvas – the helium flash happens in a star's core when helium fuses into carbon and releases a sudden surge of energy, causing the core to expand. This expansion is all part of the star's natural process towards a more stable phase, much like adding layers to create a beautiful and harmonious painting. Remember, nature always finds its way to balance and beauty.
How is possible for one tank of helium to fill 700 balloon?
Helium is stored under pressure, so a lot is packed into a small space. The gas in the balloon is at only slightly more than normal air pressure. The helium spreads out as it fills the balloons.
What is the partial pressure of helium?
The pressure that there would be if all the non-helium atoms and molecules were taken away.
What is the pressure of helium?
The pressure that there would be if all the non-helium atoms and molecules were taken away.
What is the relationship between helium pressure and its effects on gas-filled balloons?
The relationship between helium pressure and its effects on gas-filled balloons is that as the pressure of helium inside the balloon increases, the balloon expands and rises. This is because the higher pressure of helium pushes against the walls of the balloon, causing it to inflate and float.
What form of helium is filled in helium cylinders?
Gas under high pressure
What substance is not a solid at 20C and one atmosphere of pressure?
At 20°C and one atmosphere of pressure, helium is not a solid. Helium exists as a gas at this temperature and pressure.
Will a basketball blow up if you put helium in it?
That all depends how much helium you put in it. A basketball should be able to take the same amount of pressure, whether it's pressure from air or helium. So, if you inflate it only to the recommended pressure, it should be a problem. The same amount of pressure of helium will be less mass, so in the end the basketball will be lighter, as you would probably expect, by a very small amount.
What is the effect of pressure on helium inversion temperature?
The inversion temperature of helium, which is the temperature below which helium behaves as a liquid and above which it behaves as a gas, is affected by pressure. As pressure increases, the inversion temperature rises. This occurs because higher pressure forces helium atoms closer together, enhancing their interactions and requiring a higher thermal energy (temperature) to achieve the transition from liquid to gas. Thus, the relationship demonstrates the influence of pressure on the phase behavior of helium.
What is the equation for the creation of helium?
Hydrogen + intense heat and pressure --> Helium + energy release
A 6.00L gas tank contained a mixture of helium and oxygen at a pressure of 20.1 ATM. If the mixture was 75 helium what were the partial pressures of oxygen and helium?
To find the partial pressures of helium and oxygen in the gas tank, we can use Dalton's Law of Partial Pressures. Given that the mixture is 75% helium, the partial pressure of helium (P_He) is 75% of the total pressure: P_He = 0.75 × 20.1 ATM = 15.075 ATM. The remaining 25% is oxygen, so the partial pressure of oxygen (P_O2) is 25% of the total pressure: P_O2 = 0.25 × 20.1 ATM = 5.025 ATM.
What is the gas stored at the lowest pressure?
The gas stored at the lowest pressure is helium.
Why does helium balloons pop in the hot sun and what pressure is acting on it?
Helium expands in the heat, causing the gas inside the balloon to increase in pressure. As the pressure inside the balloon becomes greater than the strength of the balloon's material, it can pop. The pressure acting on the balloon is the sum of the internal pressure of the expanding helium gas and the external atmospheric pressure.
