What happens when 2 liquids of different temperatures are mixed?

When two liquids at different temperatures are mixed and the resultant temperature is found to be the mean of their temperatures then their densities must be equal.

What happens when two liquids of different densities are mixed?

When you attempt to mix two liquids which have different densities, they separate when you stop mixing them. The “heavier” liquid deposits itself on the bottom and the “lighter” liquid deposits itself on top. Molasses is most dense while alcohol is the least dense liquid.

Is the energy transferred between objects that are in different temperatures?

Two objects with different temperatures can exchange energy, if they are in thermal contact. The energy exchanged between object because they are in thermal contact is called heat.

What happens when thermal energy is added to a fluid?

When energy is added to a liquid at the boiling temperature, its converts the liquid into a gas at the same temperature. In this case, the energy added to the liquid goes into breaking the bonds between the liquid molecules without causing the temperature to change.

What happens to the temperature when you mix hot and cold water?

Because the hot water will heat the cold water up and the cold water will cool the hot water down until they have the same temperature. There is more energy in the hot water than the cold water. When the hot & cold water mix, the energy evens out so the temperature will be averaged.

When two samples at different temperatures are mixed the temperature of the mixture can be?

When two samples at different temperatures are mixed, the temperature of the mixture can be. average of lower and higher temperature.

How does density affect mixing?

Fluid with a higher density pushes a less dense fluid from channel walls and somewhat envelops it. When fluids density ratio increases, this effect is amplified; that results in an increase of the interface area of miscible fluids and consequently the enhancement of the mixing efficiency in this regime (see Fig. 2a).

Why do some liquid materials do not completely mixed combined with other liquids?

This is due to the miscibility of the different liquids. If liquids have a very different chemical structure that makes one polar and the other one unpolar, they will not mix and always stay separate.

How does thermal energy transfer between objects in contact with different temperatures?

If two objects at different temperatures are brought in contact with each other, energy is transferred from the hotter object (that is, the object with the greater temperature) to the colder (lower temperature) object, until both objects are at the same temperature.

How does heat cause a change in the degree of temperature?

If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder. The effect of this transfer of energy usually, but not always, is an increase in the temperature of the colder body and a decrease in the temperature of the hotter body.

When thermal energy is increased in a liquid What change in state is happening?

When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation).

How does a change in thermal energy cause matter to change from one state to another?

Matter can change from one state to another when thermal energy is absorbed or released. This change is known as change of state. The graph in Figure 11 shows the changes in temperature as thermal energy is gradually added to a container of ice. heated, it absorbs thermal energy and its temperature rises.

Can two substances of different materials have the same temperature?

assuming you mean a solid and liquid of different (has to be different) materials. Temperature is a measure proportional to the average kinetic energy of each particle. So if we keep the number of moles (molecules) the same in the solid and liquid in question, then theoretically yes.

Is the temperature of a solid and a liquid the same?

$\\begingroup$ assuming you mean a solid and liquid of different (has to be different) materials. Temperature is a measure proportional to the average kinetic energy of each particle.

Is temperature directly proportional to the number of molecules in a substance?

Temperature is a measure proportional to the average kinetic energy of each particle. So if we keep the number of moles (molecules) the same in the solid and liquid in question, then theoretically yes. But we can’t ignore the chemical properties of the substances (interactions between molecules) if we’re to be realistic.

What is the relationship between kinetic energy and temperature?

More generally, however, you would not expect there to be a general relationship between the kinetic energy and temperature. In particular in a solid at at low temperatures, where it is necessary to take account of the quatisation of atomic energy levels, the equipartition theorem will not hold.
