The length of time that a helium balloon will float depends on many factors that include inflation level, temperature, size and material of the balloon and if it is sealed with a product like Hi-Float. For example, a lat... More » Science Chemistry

A common helium-filled latex balloon lasts from about 12 hours up to two days. However, the size, type of material, and presence of a sealant all affect the balloon's lifespan. The treatment and level of activity to whic... More »

Latex balloons filled with helium last between 12 to 48 hours, depending on the size of the balloons; if filled with Hi-Float they last about two to 14 days. Hi-Float is a liquid protective coating that is inserted into ... More »

The length of time that gammon steak should cook for depends on many factors, including the size and thickness of the meat; however, like other types of pork, gammon steak should cook until it reaches an internal tempera... More »

As of 2015, all modern airships, party balloons and many weather balloons are inflated using helium. Helium is a lighter-than-air gas that is relatively inert, especially in comparison to hydrogen, another gas that is so... More » Science Chemistry

At today's rate in 2015, the world will run out of helium in 25 to 30 years, and that means much more than losing birthday balloons. Helium is critical to operating medical equipment, electronics and even NASA technology... More » Science Chemistry

The 13 elements that are room temperature gases are radon (Rn), xenon (Xe), krypton (Kr), argon (Ar), chlorine (Cl), neon (Ne), fluorine (F), oxygen (O), nitrogen (N), helium (He) and hydrogen (H). Most non-metals in the... More »
