A cylinder containing hydrogen gas

In summary, a cylinder containing hydrogen gas is a pressurized container used to store hydrogen gas, which is a colorless, odorless, and highly flammable gas. It is the lightest and most abundant element in the universe and is stored in a sealed container under high pressure. Safety precautions should be taken when handling this gas, and it is commonly used in scientific research for various applications.

Homework Statement



A cylinder contains 270 L of hydrogen gas (H2 at 0.0 C) and a pressure of 10 atm. How much energy is required to raise the temperature of this gas to 31°C? (answer needs to be kJ)

Homework Equations


PV =nRT
and
Q= MCT



The Attempt at a Solution


PV = nRT==> M= .12061 kg
Q = MC T
(.12061)(.014304) (31) ====> also tried using kelvins instead of celsius for temp...neither has worked

The MW of H2= 2 gms so your mass is off by a factor of 2 as well.
 

Related to A cylinder containing hydrogen gas

1. What is a cylinder containing hydrogen gas?

A cylinder containing hydrogen gas is a pressurized container that holds hydrogen gas, a colorless, odorless, and highly flammable gas. It is commonly used in various industries and research laboratories.

2. What are the properties of hydrogen gas?

Hydrogen gas is the lightest and most abundant element in the universe. It is highly flammable and burns with a pale blue flame. It is also odorless and tasteless, making it difficult to detect.

3. How is hydrogen gas stored in a cylinder?

Hydrogen gas is stored in a cylinder under high pressure, typically around 2000-2500 psi. The gas is compressed and stored in a sealed container to prevent it from escaping into the atmosphere.

4. What are the safety precautions when handling a cylinder containing hydrogen gas?

Some safety precautions when handling a cylinder containing hydrogen gas include wearing protective gear, such as gloves and goggles, and ensuring proper ventilation to prevent buildup of hydrogen gas. It is also important to handle the cylinder carefully and avoid dropping or damaging it.

5. How is hydrogen gas used in scientific research?

Hydrogen gas is used in various scientific research applications, such as fuel cell technology, hydrogenation reactions, and as a reducing agent in chemical reactions. It is also used in gas chromatography and as a carrier gas in analytical instrumentation.
