A vacuum pump is used to perform this process during lyophilization.
The energy required to perform this process is approximately equal to negative lattice energy minus two RT. Precise measurements of this process are used to calculate vapor pressures using a Knudsen effusion cell. A vacuum pump is used to perform this process during lyophilization. It's not recrystallization, but this process is typically used to purify nickelocene and ferrocene. Collecting the products of this process in the lab involves using a spatula to scrape the product off a (*) cold finger. Mothballs work because naphthalene undergoes this process at room temperature. The enthalpy change of this process equals the sum of the enthalpies of fusion and vaporization. For 10 points, the reverse of deposition is what direct transition from a solid to a gas?
