The pressure above a pure sample of solid Substance X at -221. °C is lowered. At what pressure will the sample sublime? Use the phase diagram of X below to find your answer. solid 벼 liquid gas 100 temperature (K) pressure (atm) 200

The temperature on a sample of pure X held at 0.53 atm and – 168. °C is increased until the sample sublimes. The temperature is then held constant and the pressure is decreased by 0.35 atm. On the phase diagram below draw a path that shows this set of changes. pressure (atm) 3 دنا 2- 0. ایل 200 temperature (K) 400 x 5

The pressure above a pure sample of solid Substance X at -142. °C is raised. At what pressure will the sample melt? Use the phase diagram of X below to find your answer. بالا pressure (atm) 0 0. atm solid liquid 200 temperature (K) Note: your answer must be within 0.125 atm of the exact answer to be graded correct. gas X 400

Labelling a typical simple phase diagram.

This question as been getting rejected, but this is not a grade assigment. This just a pratice problem.

The pressure above a pure sample of solid Substance X at -10. °C is lowered. At what pressure will the sample melt? Use the phase diagram of X below to find your answer. pressure (atm) 04- 02- 6 0 atm solid liquid 400 temperature (K) Note: your answer must be within 0.025 atm of the exact answer to be graded correct. gas 600

Need answers for the blue parts,thank you!!

The pressure above a pure sample of solid Substance X at -146. °C is lowered. At what pressure will the sample sublime? Use the phase diagram of X below to find your answer. pressure (atm) solid 200 liquid temperature (K) 400 gas Note: your answer must be within 0.5 atm of the exact answer to be graded correct.

Use the phase diagram of Substance X below to find the melting point of X when the pressure above the solid is 7.0 atm. بالا pressure (atm) solid []c 200 liquid 400 X gas temperature (K) Note: your answer must be within 25 °C of the exact answer to be graded correct. 600

The pressure above a pure sample of solid Substance X at -5. °C is lowered. At what pressure will the sample melt?
