solid
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. The atoms in a solid are bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice), or irregularly (an amorphous solid such as common window glass). Solids cannot be compressed with little pressure whereas gases can be compressed with little pressure because the molecules in a gas are loosely packed.
The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science is primarily concerned with the physical and chemical properties of solids. Solid-state chemistry is especially concerned with the synthesis of novel materials, as well as the science of identification and chemical composition.
Hey a question about solid fuel boilers and pipe stats.
If you had a house with central heating and the house only got luke warm the pump seemed to be running (vibrating when touched) checked pipes coming from boiler they were hot could hold them for say 2 seconds so not steaming.
The only...

Hi guys, first post on these forums. I have a multifuel stove which can be converted into a boiler via a bolt-in 3-4kw 1 input/1 output boiler (picture attached), this is available on Ebay. I am undecided which is the best way to plumb it in. I know 3kw is relatively small, but I was planning in...

We have a customer with a solid fuel (coal) fire and old fashioned back-boiler behind it. We are fitting a new combi system but the customer wants to keep the fire. Obviously the BBU needs to be safe and I have heard of them being 'drilled' to make sure there is no pressure build up inside when...

Hello!
I am renovating a cottage and am starting from scratch with the heating system because the original boiler consisted a massive iron tank with 5 immersion heaters in it, which cost a fortune to run and wasn't all that effective, and the radiator circuit is very very old and needs to be...

Could anyone tell me is there much work involved in taking out a HAMCO solid fuel stove and replacing it with one of those pot belly solid fuel heaters. The Hamco stove does hot water and heats the rads as well,and is linked up to an oil boiler. Is it just a matter of draining the system down...
