Gas.
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.
Helium is typically pumped into balloons because it is lighter than air and gives the balloon its ability to float.
a helium balloon is forced upward by buoyancy. a object is forced upward by a force equal to the weight of the fluid it displaces. this also applies to gases. the gas helium is lighter than average atmospheric air, that is that equal volumes of atmospheric air and helium do not weigh the same. This means that the volume displaced by the balloon is heavier than the balloon itself. since the air weighs more it applies more force upwards on the balloon than the balloon applies downwards on the air, therefore it rises. However, a helium balloon will not go down unless a force such as large air resistance (heavy wind etc.) is applied to it. hope this helps.
Helium typically fills a balloon faster than air because it is less dense than air and flows easily into the balloon. Helium is also less likely to escape from the balloon due to its smaller molecular size compared to the molecules in air.
Helium is an element (and therefore a pure substance) yes
No, the contents of a helium balloon are in the gas phase. Plasma is the fourth state of matter, which consists of charged particles such as electrons and ions.
Matter is anything that has volume and occupies space. Helium (in balloon) is a gas and has both these properties. So. it is an example of matter.
Helium is a gas at STP.
Helium is a gas at room temperature.
helium is a gas at room temperature.
A balloon has mass because it is made of matter, specifically latex or rubber. Even though a balloon filled with helium or air may feel light, it still has mass, which is the amount of matter it contains.
gaseous state
At room temperature (25o), helium is a gas
Helium, hydrogen, and air are gases.
depends how big the helium balloon is and how many
It was made out of the light gas gas Helium.
