A solid solute can be recovered from a solution by evaporating the solvent completely.

This can be done by heating the solution appropriately. Heating a solution with organic solutes such as sugar will most likely destroy the solute so it's best to let the solution stand in an open area and let it evaporate by itself. However, if you have an inorganic solute such as salt (NaCl), you can completely boil out the water without any problem.

Also, in a research laboratory, a rotary evaporator is commonly used. This instrument employs the principle of vacuum distillation and is used in mainly in removing solvents in solutions.

Describe how the energy consumption of appliances is dependent on the power rating of an appliance and the length of time that t

lawyer [7]

Answer:

Different appliances and machines are analyzed on the basis of the energy that each of the machine or appliance consumes in a given time. As, we know that the voltage is the amount or level of difference between the energy possessed by the different points or devices.

As, the required amount of energy required to run the machine or any device is consumed from the reservoir of the potential reservoir, as there is a certain scale of time, T and power,P on which the different machines are analyzed in more proper way and find its total efficiency in the mean time,T.
However, the power rating or power consumption is the amount of voltage dissipated during the working of the device and the amount of current, I flowing through the device's system. As, if we analyze the over all working of the system on the given scale of time,T. As the level of energy consumed and the current passed through these system give us the power ratings,P(rating) on a given scale of time,T.
The unit will be watt per hour for the power in the given amount of time.
