What is the density of helium at 25 degrees celsius and one atmosphere of pressure?
WATER
Will a lit cigarette ignite a helium balloon?
Helium is not flammable. However, the cigarette might puncture the balloon.
Why does a balloon filled with helium rise with a balloon filled with an equal volume of average atmospheric air does not?
Helium is less dense than air, which is why the helium-filled balloon floats when you let it go.
How does a helium balloon float but not a balloon filled with air?
Helium is a lighter element compared to air, helium also has fewer molecules than air.
Does a hot air balloon have helium inside it?
No, I am sorry, but there is no helium inside a hot-air balloon. Instead, there is hot air.
What is the diffusion rate of temperature at 5 degrees Celsius?
If I have 45 liters of helium in a balloon at 250 C and increase the temperature of the balloon to 550 C, what will the new volume of the balloon be?
A balloon has a volume of 6.3 liters Calculate the mass of helium that it would take to fill the balloon?
The mass of helium contained will be 1 gram.
The freezing point of helium is -272 degrees Celsius The original temperature of a sample of helium is 3 degrees Celsius how much must the temperature change to ensure that helium freezes?
275 degrees
What is the the melting point of helium?
-1480 degrees Celsius
What is the density of helium at 25 degrees celsius and one atmosphere of pressure?
WATER
What is the melting point and the boiling point of helium in degrees Celsius?
Helium melts at −272.20 °C and boils at −268.93 °C
What is helium like at 20 degrees?
it is a colourless odourless gas at 20 degree Celsius
What is that something really cold?
Liquid helium, it liquefies at -230 to -240 degrees Celsius.
Is a helium balloon a solid?
A helium "balloon" is composed of two parts: the SOLID rubber balloon skin, and the GASeous helium. So the balloon part itself is a solid.
What was the helium balloon balloon made of?
It was made out of the light gas gas Helium.
How much can a helium balloon lift?
depends how big the helium balloon is and how many
What makes a child's balloon rise?
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
