Yes, its to do with the gas density difference of air and helium, rather than the density of gas due to temperature.

What kind of gas is inside a weather balloon?
Contemporary weather balloons are usually filled with helium. Helium is lighter than air, and this allows the balloon to rise as this gas is lighter than air.Hydrogen would also work as it has a low density, like helium. And hydrogen is a bit cheaper than helium because it can be "made" from water. But hydrogen is flammable or even explosive, and it is generally not used for that reason.
How often do temperatures drop below freezing in california?
California is a relatively warm state. The weather rarely drops below freezing in southern California. However, northern California has very cold winters.
What temperature is helium a solid?
The lowest freezing point of all the elements of 1.1 K are: (-272.05 °C or -458 °F).
How many cubic inches of helium does it take to lift 500lbs?
Let's assume you are talking about filling a balloon with helium and using it to lift a 500 pound weight. Unfortunately, there are more factors you need to consider before you can have this question resolved. You need to know the atmospheric temperature, the density of the outside air, the temperature of the helium you're using, and the starting point in relation to the Earth's center of gravity. Also, are you including the weight of the balloon and the rest of your apparatus in the 500 pound figure, if not you need to allow for that. In other words, if you are starting from the top of Everest at 30 below zero, the amount of helium you'll need varies greatly from that of a balloon starting in Death Valley at 120 degrees.
What is below permafrost?
Below permafrost is below freezing temperature (0c)

What is helium's freezing point?
Well, everything has its own unique freezing/melting and boiling. Helium, has a freezing/melting point of -310 degrees Celsius, or in other words, when it is below -310 it is a solid and when it is above -310 it is a liquid.
What is the temperature for boiling Helium?
4.2Kelvin or better yet - 268.9 °c - it is not measurable in Fahrenheit (well below freezing)
How does a hot air balloon come down?
In rising, a hot air balloon works the same way as a helium balloon : the hot air inside is less dense than the surrounding air outside the balloon. The heavier outside air pushes below the balloon and forces it upward. To come down is easier in a hot air balloon. Unless it is continually reheated, its temperature reverts to that of the surrounding air and the balloon settles back to the Earth under its own weight. Vents that release the heated air (like venting helium in a helium balloon) is an alternative to increase the speed of descent.
Can a balloon filled with hydrogen gas lift a beaker?
It depends on the balloon's size, the ambient conditions, and the weight of the beaker, so theoretically it can be done. However, in practice, you are unlikely to have a balloon with a large enough volume. Something approaching weather balloon size would do it, certainly, but your average party balloon? Not a chance. helium or hot air makes a better choice. Hydrogen is very flammable. Check out the Story on the Hindenburg which I posted in the related links box below.

Why cant snow come down in warm weather?
Snow is frozen water, so it needs to be below freezing for it to form and generally for it to fall. In fact, rain often does start as snow (in cooler weather - not so much in the summer) because it is below freezing in the clouds, but it melts as it falls through warmer air closer to the ground.
Does a refrigerator keep food warm in below freezing weather?
Yes it does, I keep bottled water and cans of soda in mine in my unheated garage when the temp drops below freezing in the garage and it works for me. I am sure that if it was for a long cold spell it would eventually freeze.
Can arctic wolves survive in freezing cold weather?
They live in the Arctic, you idiot. Of course they can survive the cold.
What is the difference between 82 degrees and negative 12?
82 degrees is warm weather and negative 12 is below zero. So as you can guess, it's freezing weather! haha. Who asked this question?
How many degrees below freezing is-20f?
Since +32F is freezing, -20 F is 52 degrees Fahrenheit below freezing.
