The process of sublimation describes which of the following changes of state?

liquid ➡ solid

gas ➡ solid

solid ➡ gas

gas ➡ liquid

The sublimation process describes the change of state solid → gas.

Explanation:

Sublimation is a process that involves the passage of a substance from the solid to the gaseous state, without going through the liquid state. The inverse process is known as "inverse or regressive sublimation" and consists in solidifying (going to solid state) again the gas obtained, without going through the liquid state.

Frequently, it can be considered as a special form of distillation of certain solid substances, in which a sublimator is used, which is a special vessel that heats the solid substance until it passes into the gas phase.

Then, the sublimation process describes the change of state solid → gas.

gravity causes stares to cluster i think so

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
