WebSep 3, 2024 · Sublimation is the change of state from a solid to a gas, without passing through the liquid state. Deposition is the change of state from a gas to a solid. Carbon dioxide is an example of a material that easily undergoes sublimation. The melting point is the temperature at which a solid changes into a liquid. WebNaphthalene, a common ingredient in mothballs, also sublimes easily. Arsenic can also sublime at high temperatures. Sublimation requires additional energy and is an endothermic change. The enthalpy of sublimation can be calculated as the enthalpy of fusion plus the enthalpy of vaporization .
