gas
Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma).A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas invisible to the human observer.
The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention.
High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensive listing of these exotic states of matter see list of states of matter.
Hi
Having lived in a new build for 14 years, on trying to replace our two boilers I’ve been told the installation is dangerous (and has always been so and one boiler has been shut down. The diameter of the pipe from the mains (on one side of the house, which runs under the floor to the boilers...
We are taking over the running of a small cafe that has a commercial gas cooker and is supplied by gas canisters that automatically change from one bottle to the other.

Hi, Please can someone advise me on the correct replacement parts to re-connect my gas hob? It is an Indesit PIM 640 AS fitted gas hob and the manual states the fitting is a threaded 1/2 gas cyclindrical male attachment. Do I also need to order a fibre washer or o-ring for this? If so which size...

I have gas fired central heating and hot water system. It is on a timer, but, in winter, I leave the central heating on and the thermostat set low - 17c. I'm well insulated so the heating comes on infrequently but enough to keep the house warm enough for a family of three.
Here's the problem...
Hello Plumbers. We had a gas fire fitted, one of those that looks like a log burner. I need to take it out to paint the wall behind. It has a restrictor valve under it but no isolating valve that I can see. Is the restrictor an isolator as well? Should there be a separate isolating valve? Is it...
Hi all,
My customer has a gas fire with an external gas pipe (runs across the front of the fire - see pic).
He'd like a new gas fire. No chance of re-running the pipe through the chimney opening.
Any ideas of a gas fire that would suit? I've looked at a few, but would like the gas connections...
Anyone recommend a flue gas analyser. My old Kane needs a replacement and they all seem to have gone up in price.
Someone suggested bluelyzer but I've never heard of them.
Can someone in the know kindly clarify, please? I have tried to get Gas Safe on the phone, but no good!
I have had conflicting advice. I am in the position of being able to start a small business employing two nephews - both of whom are Gas Safe registered. But do I have to ensure the business...
We recently had a power cut for 3 days and when it came back on I thought I would have a look at the smart meter. As expected I had 2 full days of no use of electricity. However when I went to look at my gas usage it looked almost normal usage during the whole period. Gas in my house only...

Hi all,
I’m looking for a course that will cover the necessary certificates for me to obtain the gas safe status. I’ve come across a few providers who offer, training, hands on experience and the exam, but I’m torn on which one to go for.
