The mass diffusivity of liquid mixtures generally increases with temperature, as higher temperatures enhance molecular motion and reduce viscosity, facilitating the movement of species within the mixture. Conversely, the effect of pressure on mass diffusivity is more complex; while increased pressure can lead to a decrease in diffusivity due to higher density and reduced intermolecular spacing, the impact is often less pronounced than that of temperature. In many cases, the overall relationship between diffusivity, temperature, and pressure can be described by empirical correlations or models.

1) Increase in heat 2)Decrease in volume
Temperature and pressure are two factors that can cause a phase change in a substance. A substance will change from one phase to another when its temperature or pressure surpass a certain threshold, known as the melting point, boiling point, or sublimation point.
"Constant pressure" means the pressure must not change.
Volume ChangesThe volume of any solid, liquid, or gas will change with changes in temperature.
Temperature or pressure
Temperature, pressure.
The boiling temperature of an element can change by changing the pressure.
Solutions can be change due to change in volume, temperature, and or pressure. Some solutions can be separated. For example, scientists use the process of distillation to separate a solution of alcohol and water.

The pressure and temperature mostly the temperature.
Change the pressure or change the temperature. Volume changes inversely with pressure and directly with temperature. That is to say, if you squeeze it, it gets smaller. If you heat it, it gets bigger.
1) Increase in heat 2)Decrease in volume
Both temperature and pressure increase.
Change the pressure and/or the temperature of the gas.
