Specific heat of liquid nitrogen
WebAug 16, 2024 · The temperature of liquid nitrogen is −195.79 °C (77 K; −320 °F). Liquid nitrogen has many uses, but poses risks of frostbite, explosion, and suffocation if handled … WebSpecific heat represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as: q = m⋅ c ⋅ ΔT, where q - the amount of heat supplied; m - the mass of the substance; c - the respective substance's specific heat; ΔT - the change in temperature.
