Assuming constant volume, if you increase temperature, the pressure will increase. So it is B: increasing

Assume that the gas being referred to above is ideal such that by Gay - Lussac's Law:
T1P2 = T2P1
Thus, increasing the value of the temperature, would also correspond to an increase in the value of the pressure. This is because the molecules are moving faster at a higher temperature.

How do organisms interact with each other and how can one organism be dependent upon other species

Vadim26 [7]

Individual organisms live together in an ecosystem and depend on one another. ... One category of interactions describes the different ways organisms obtain their food and energy. Some organisms can make their own food, and other organisms have to get their food by eating other organisms.

The heat of vaporization, ΔHvap of carbon tetrachloride (CCl4) is 43000 J/mol at 25 °C. 1 mol of liquid CCl4 has an entropy of 2

Alexxandr [17]

Explanation:

(a) The given data is as follows.

Temperature (T) = $25^{o}C$ = (25 + 273) K = 298 K

$\Delta H_{vap}$ = 43000 J/mol

Since, both the liquid and vapors are at equilibrium. Therefore, change in free energy will be calculated as follows.

$\Delta G_{vap} = \Delta H_{vap} - T \Delta S_{vap}$ = 0

43000 - $(298 \times \Delta S_{vap})$ = 0

$\Delta S_{vap}$ = -144 J/mol K

Negative sign indicates an increase in entropy of the system.

Now, for 1 mole of $CCl_{4}$ is as follows.

= 144 J/K

So, $S_{vapor}$ - 214 = 144 J/k

= 358 J/K

Therefore, we can conclude that entropy of $CCl_{4}$ vapor is 358 J/K.

(b) As we know that intensive variable are the variables which do not depend on the amount of a substance.

So, in the given situation only temperature will act as an intensive variable that will be required to completely specify the vapor-liquid mixture of $CCl_{4}$ .
