Question

Click on the value of the pressure on the y-axis of the phase diagram that needs to be applied to liquefy at room temperature in Tucson (300 K).

Options:

Low pressure
Moderate pressure
High pressure
Ultra-high pressure

Answer 1

The pressure value on the y-axis of the phase diagram that needs to be applied to liquefy a substance at room temperature in Tucson (300 K) depends on the substance and its critical temperature and pressure.

Step-by-step explanation:

The pressure value on the y-axis of the phase diagram that needs to be applied to liquefy a substance at room temperature in Tucson (300 K) depends on the substance. If the substance has a high critical temperature, a high pressure would be required to liquefy it at room temperature. However, if the substance has a low critical temperature, a low pressure would be sufficient to liquefy it at room temperature.

In the given information, the critical temperatures and pressures of some common substances are not provided, so it is not possible to determine the exact pressure value required to liquefy a substance at room temperature in Tucson. Therefore, we cannot determine if the pressure required would be low, moderate, high, or ultra-high.
