Question

In what phase is CO2 at 4 atm and -10°C is liquid, gas or solid? Starting from the same point, 4 atm and −10 °C, what phase change would eventually result from an increase in pressure?

a. vaporization
b. sublimation
c. freezing
d. deposition
e. melting
f. condensation

Answer 1

Answer:

(f).Condensation

CO2 exist as gaseous state at -10degree 4atm pressure and will become liquid upon increasing the pressure  

Explanation:

Using The phase diagram of CO2 we observe that

Carbon dioxide at -10degree Celsius and 4atm pressure will be in

Gaseous phase. Starting from the same point, 4atm and -10degree Celsius upon increasing the pressure the Carbon dioxide will change into liquid phase above 5.11atm pressure, this happened due to Condensation.

Therefore CO2 exist as gaseous state at -10degree 4atm pressure and will become liquid upon increasing the pressure till 5.11stm.  

Answer 2

The carbon dioxide has been existing in the gaseous state and with condensation, it has been converted to the liquid state. Thus, option F is correct.

The state of the gas at a particular pressure and temperature can be assessed from the phase diagram.

The state of Carbon dioxide at 4 atm and $\rm -10^\circ C$ have been the gaseous state.

The increase in pressure results in the decrease in the volume of the gas, as the pressure has been increased, the molecules will condense and result in the conversion of the gaseous state to the liquid state.

The carbon dioxide has been existing in the gaseous state at 4 atm and $\rm -10^\circ C$.  With the increase in pressure, the state of the gas has been changed to liquid due to condensation. Thus option F is correct.
