The most common and cost-effective technology is natural gas reforming. It involves combining natural gas with high-temperature steam to generate synthesis gas, which is a combination of hydrogen, carbon monoxide, and a trace of carbon dioxide. Carbon monoxide and water can be combined to produce more hydrogen. Another method is gasification, which involves combining coal or biomass with steam and oxygen to generate synthesis gas containing hydrogen and carbon monoxide.

What is the difference between GAS and VAPOURS ?

Gas: A substance that is in a gaseous form at room temperature and pressure is referred to as gas. For instance, air is a gas because, at room temperature and pressure, it is in a gaseous form. The gases oxygen, nitrogen, and carbon dioxide are additional instances.

Vapour: It is a term used to describe a substance that is in a gaseous state, but is typically a liquid or solid at room temperature and pressure. When a liquid or solid substance is heated, it can evaporate and become a vapor. For example, when water is heated, it evaporates and becomes water vapor, which is a gas. Similarly, when dry ice is exposed to air, it sublimates and becomes carbon dioxide vapor, which is also a gas.

Summary: The key difference between gas and vapor is that gas refers to a substance…

Which substance is used in refrigerators now a days instead of CFC?

Chlorofluorocarbons (CFCs) were once widely employed in air conditioners and refrigerators, but it was later discovered that they were damaging to the ozone layer. CFCs were gradually phased out in response, and as a result, they are now largely prohibited by the Montreal Protocol.

To understand the reason, go through this image. Source: Google images

Hydrofluorocarbons (HFCs), such as R-134a and R-410A, are currently the most widely used refrigerants in refrigerators and air conditioners. However, it has also been established that HFCs play a role in climate change, and the Kigali Amendment to the Montreal Protocol has begun to phase down their use. HFCs are being replaced by more modern refrigerants like hydrofluoroolefins (HFOs) and natural refrigerants like carbon dioxide and ammonia.

Why does water boil at a lower temperature on the hills than on the plains?

Water boils at a lower temperature at higher altitudes because the atmospheric pressure is lower.

At sea level, the atmospheric pressure is about 1013 millibars and the boiling point of water is 100°C (212°F). However, as you move higher in elevation, the atmospheric pressure decreases. This means that at a higher altitude, the boiling point of water is lower.

The boiling point of water decreases about 0.5°C for every 300 meters of altitude gain. This is due to the decrease in atmospheric pressure. The atmospheric pressure at an elevation of 3,000 meters is about 68% of that at sea level. At this elevation, the boiling point of water is around 93°C (199.4°F).

This decrease in boiling point can have practical implications for cooking at high elevations. When boiling water at high altitude, it will take…
