What substance, if added to the mixture of salt and sand, could be separated from the mixture using a sieve?

Physics
1 answer:
bija089 [108]3 years ago
3 0
Answer:

It is easy to separate sand and water by filtering the mixture. Salt can be separated from a solution through evaporation. The water can also be recovered as well as the salt if the water vapour is trapped and cooled to condense the water vapour back into a liquid. This process is called distillation.

Which of the following summarizes cellular respiration?
3241004551 [841]

The statement which summarizes cellular respiration is Oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

<h3>What is cellular respiration?</h3>

Cellular respiration is the process by which food, in the form of glucose is transformed into energy within cells.

The food is prepared by the plants by the process of photosynthesis in presence of sunlight. This food is in the form of glucose.

The respiration of plants is done by breaking of glucose by absorbing oxygen. This produces  carbon- di- oxide and water along with the release of energy.

Thus, the cellular respiration is oxygen reacts with glucose to produce carbon dioxide and water, and release energy.

Under what condition will the enthalpy change of a process equal the amount of heat transferred into or out of the system?
olga55 [171]

Answer:

At constant pressure

Explanation:

Enthalpy of a system may be defined as the system's internal energy in addition to the product of the volume and pressure of the system.

It can be regarded as the system's capacity of heat transfer and to do non- mechanical work.

The enthalpy of the system at constant pressure gives the amount of heat or energy that is either absorbed by the system or released by the system.

Describe the nature of sunlight using the following: wavelength, electromagnetic spectrum, visible light, photons.
kogti [31]

Answer:

due to the effect of gravity begins thermonuclear fusion processes, in these processes energy is released in the form of electromagnetic radiation

Explanation:

The Sun is a star of great size, which due to the effect of gravity begins thermonuclear fusion processes, in these processes energy is released in the form of electromagnetic radiation.

This radiation crosses the different layers of the Sun and escapes from it in the form of light that is emitted throughout the radiation spectrum, due to the temperature reached by the Sun about 5500K the most likely radiation is around 5500 nm corresponding to the green- yellow of the visible spectrum, but the entire spectrum is emitted with different intensity according to Stefan's law

     

In quantum mechanics this spectrum can also be analyzed as the emission of particles called photons, where each one is characterized by an energy and has a moment equal to zero, the energy of these photons is related to their frequency by the Planck equation

                   E = h f
