  • Fire belongs to which state of matter - Physics Stack Exchange
    Every thing is matter So In which state of matter fire will be considered? I haven't get it's proper answer
  • heat - Is fire plasma? - Physics Stack Exchange
    Firstly, 'Fire', according to numerous comments and answers [here] [1] is a 'process', in which case, the answer to the question will be 'no', since plasma is a state of matter
  • To which state of matter does the flame belong to?
    2 I had this question from the day (9 years old, now 16) that i learned about states of matter I have asked so many of my teachers some of them told me gas some as plasma etc can anyone answer my question? Recently I've learnt that plasma state is obtained when all the electrons from the atom are removed
  • definition - What is a heat engine in thermodynamics? Is is cyclical . . .
    Technically, we have two different devices, one requiring insulation and one requiring no insulation For that matter, can we even say the device doing work during the adiabatic expansion is a "heat engine" at all when it is producing work without any heat (the energy coming from the internal energy of the gas)!
  • thermodynamics - Burning VS Melting: What is the relation in the atomic . . .
    Burning is a phenomenon with heat, flame, etc Typically it is a reaction with oxygen Water does not react with oxygen, at least in normal condition Melting is a phase transition from solid to liquid, without reaction with external substance, such as oxygen
  • Could a gas go directly to a solid without becoming a liquid?
    A solid has particles with lower amounts of kinetic energy and they are vibrating slower without changing position This change of state from a gas to a solid is not a very common phase change but is referred to as deposition It is called deposition because the particles in the gas form are depositing into a solid form Examples of Gas to Solid:
  • Is a plasma a distinct phase of matter? - Physics Stack Exchange
    When a material changes from a distinct phase to another, it goes through a physical process called phase transition When gas becomes plasma, it doesn't go through the standard phase transition Hence plasma-in a general sense-can't be regarded as a distinct phase as solid, liquid and gas phases It is a phase of the gaseous state
  • If two objects of different temperatures have the same heat source . . .
    The matter is mostly or entirely in the same phase throughout the event The temperature of A is 100 degrees The temperature of B is 200 degrees Applying a heat source raises the temperature of A by 10 degrees up to 110 degrees With no modifications, the heat source is applied to B
  • quantum mechanics - Schrodinger equation with constant potential . . .
    Differences in potential are physically meaningful, not sure why you imagine that a constant potential wouldn't be detectable since that's the basis for the difference between a particle in a finite well vs infinite well (vs a free particle)
  • Is fire matter or energy? - Physics Stack Exchange
    Fire is composed of several states of energy and matter, like sublimated matter turning into gases; or photons released on oxidization of matter; or sound is released via turbulence from convection; plasma occurs whenever the temperature ionizes atomic bonds and Sooty
