Zeppelins used hydrogen gas as the lifting gas to make them buoyant in the air.
No, Hydrogen is a gas. The verb "fly" can not be applied to a gas.
The range of a gas thermometer depends on the type of gas used. Typically, gas thermometers can measure temperatures from -200°C to 600°C using various gases like nitrogen, hydrogen, or helium. Gas thermometers have a wide range compared to other types of thermometers due to the varying pressure-temperature relationships of different gases.
HNO3 is not used in the preparation of hydrogen gas because it is a strong oxidizing agent. When HNO3 reacts with a metal to produce hydrogen gas, it tends to oxidize the hydrogen gas produced back to water, making the reaction inefficient for hydrogen gas production.
Hydrogen is a colorless, odorless, and tasteless gas that is the lightest element on the periodic table. It is highly flammable and is commonly used in industries such as petroleum refining and ammonia production.
Hydrogen gas was used to inflate the Hindenburg.
Helium is typically used in making a volume gas thermometer due to its low boiling point, inertness, and the fact that it remains a gas at very low temperatures. Additionally, helium has a very low thermal conductivity, which helps in isolating the gas in the thermometer from its surroundings.
The range of a gas thermometer depends on the type of gas used. Common gases used in gas thermometers have ranges from very low temperatures up to high temperatures, typically ranging from close to absolute zero to a few thousand degrees Celsius.
A constant volume thermometer measures temperature by keeping the volume of the gas inside the thermometer constant. As temperature changes, the pressure of the gas inside the thermometer also changes, which can be correlated to the temperature. This type of thermometer is commonly used in laboratories and for precision measurements.
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
The symbol for hydrogen gas is H2
