Oxygen and acetylene cylinders should be stored separately and upright in a well-ventilated, dry area away from heat or ignition sources. The temperature should be below their critical temperatures to maintain their state. Depending on the gases, a large storage capacity may be required.
Oxygen and acetylene cylinders are often used in applications like oxyhydrogen and oxyacetylene torches. These cylinders come with specific storage requirements to ensure safety and maintain the integrity of the gases inside.
Firstly, oxygen and acetylene cylinders should be stored separately. Oxygen is an oxidizing agent and can react with acetylene, a fuel, causing a fire or explosion if not stored correctly. Acetylene cylinders should be stored upright, as acetylene is typically dissolved in a liquid and could escape from the cylinder if stored on its side.
Storage areas should be well-ventilated, dry, and situated away from sources of heat or ignition. Cylinders should also be stored at temperatures below their critical temperatures to maintain their state. For example, for CO₂ it's around 31 °C. Above this temperature, no amount of pressure can liquefy CO₂, hence no liquid CO₂ would exist in the cylinder.
Moreover, a large storage capacity may be required. As a point of reference, it would require roughly 1020 L (269 gal) of gaseous methane at about 1 atm of pressure to replace 1 gallon of gasoline, due to differences in energy content.

Answer:
The storage requirements for oxygen and acetylene cylinders are critical to ensure safety. Here are some general guidelines:
1. **Separation**: Oxygen and acetylene cylinders should be stored separately, and there should be a minimum distance or physical barrier between them. This separation is essential because oxygen supports combustion, while acetylene is highly flammable. Keeping them apart reduces the risk of a dangerous reaction.
2. **Ventilation**: Storage areas should be well-ventilated to prevent the accumulation of gases in the event of a leak. Adequate ventilation helps dissipate any escaping gas and reduces the risk of fire or explosion.
3. **Secure Storage**: Cylinders should be stored upright and securely chained or strapped to prevent them from falling over. Falling cylinders can damage the valves or cause leaks, leading to hazardous situations.
4. **Protection from Heat and Sunlight**: Oxygen cylinders should be protected from direct sunlight and excessive heat. High temperatures can increase the pressure inside the cylinder and pose safety risks. Acetylene cylinders should also be protected from extreme heat, as they can become unstable when exposed to high temperatures.
5. **Labeling**: Cylinders should be labeled properly to indicate their contents. This helps identify gases quickly and prevents accidental mix-ups.
6. **No Smoking or Open Flames**: Smoking, open flames, or any potential sources of ignition should be prohibited in the storage area.
7. **Regular Inspection**: Cylinders should be periodically inspected for damage, corrosion, or other issues. Damaged cylinders should be removed from service and properly handled.
8. **Compliance with Regulations**: It's essential to comply with local, state, and national regulations regarding the storage and handling of compressed gases. These regulations may vary depending on your location and the specific industry.
9. **Safety Equipment**: Make sure that appropriate safety equipment, such as fire extinguishers, is readily available in the storage area in case of emergencies.
It's crucial to consult with relevant safety authorities or experts in your area to ensure that you are following all the necessary safety guidelines and regulations for storing oxygen and acetylene cylinders. These gases can be hazardous, and proper storage is essential to prevent accidents and ensure the safety of personnel and property.
Answer:
carbon 14 half life is in the thousands of years while uranium is many millions of years
Answer:true
Explanation: just took the test
Answer:
Mycelium.
Explanation:
Mycelium is a mass of thread-like hyphae that can grow on a surface, decaying material, soil or on a living tissue. It is the vegetative part of a fungus through which a fungus absorbs nutrient from the environment. They are good sources of food for soil invertebrates. They also play a major role in decomposition of plant material.
B.melting ice
C.affected human populations
D.altered ecosystems
The correct answer is (d) altered ecosystem.
The increase in the global temperature all over the world due to the harmful effect of green house gases is called global warming. The consequences of global warming can be defined as having an increase in growing seasons, changes in migration and loss of species. All the consequences mentioned here signifies altered ecosystem. The ecosystem consists of the plant and animal species that interact with the environment. Hence, global warming results in altered ecosystem.
