water density at 4 degree cel is minimum and as the temperature reduces the density decreases and at 0 deg the water density become lowest. thereafter it catches 80 kcal /kg the latet heat and starts become ice. this is the reason the ice is floating on water.

What would happen if the temperature of liquids was reduced in motion of the molecules?

As the temperature is reduced, the motion of the molecules is also reduced.


When a fixed sample of gas increases in volume what happens to the pressure and temperature?

The frequency of collisions is reduced


Why you use reduced properties?

Reduced properties allow for universal comparison of thermodynamic properties between different substances, enabling easier calculations and analysis. By normalizing properties like temperature and pressure to their critical values, reduced properties simplify the representation of thermodynamic data across a wide range of substances.


Why is a solid floating in a liquid fully immersed sinks to the bottom when the temperature of the system increased?

When the temperature of a system increases, the density of the liquid generally decreases due to thermal expansion. If the density of the liquid becomes less than that of the solid, the buoyant force acting on the solid may no longer be sufficient to keep it afloat. Consequently, the solid will sink to the bottom as the upward buoyant force is reduced compared to the weight of the solid.


How does the mass diffusivity of liquid mixtures change with temperature and pressure?

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.

What happens to the rate pf energy transfer between an object and its surroundings if the temperature difference between them is reduced?

If the temperature difference between an object and its surroundings is reduced, the rate of energy transfer between them will also decrease. This is because the driving force for heat transfer is smaller when the temperature difference is smaller.

What happens to the volume of a gas if its temperature is reduced by 25 percent?

If the temperature of a gas is reduced by 25%, its volume decreases proportionally if the pressure and quantity of gas remain constant. This is known as Charles's Law, which states that the volume of a gas is directly proportional to its absolute temperature.


Can you provide an example of a reduced density matrix?

A reduced density matrix is a way to describe the state of a subsystem within a larger quantum system. For example, if we have a two-qubit system, the reduced density matrix for one qubit would describe its state while ignoring the other qubit's information.
