Temperature Gas

air balloon shrinks after submersion in liquid nitrogen

the symbol used represent temperature in equations t si units of kelvins. speed of gas particle proportional absolute temperature. volume of balloon in video shrinks when trapped gas particles slow down addition of extremely cold nitrogen. temperature of physical system related motions of particles (molecules , atoms) make [gas] system. in statistical mechanics, temperature measure of average kinetic energy stored in particle. methods of storing energy dictated degrees of freedom of particle (energy modes). kinetic energy added (endothermic process) gas particles way of collisions produces linear, rotational, , vibrational motion. in contrast, molecule in solid can increase vibrational modes addition of heat lattice crystal structure prevents both linear , rotational motions. these heated gas molecules have greater speed range varies due constant collisions other particles. speed range can described maxwell–boltzmann distribution. use of distribution implies ideal gases near thermodynamic equilibrium system of particles being considered.
