crystallization is a process which helps to separate a pure solid from a solution in its crystal form. This is the in use to purify solid. For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.
Sugar and salt are examples of products where crystallization does not only serve as separation/purification technique, but where it is also responsible for getting crystals with the right size (and shape) for further application of the products.

The total change in internal energy would simply be
calculated using the formula:
ΔU = -P (V2 – V1) + ΔH
where ΔU is the change in internal energy; P is constant
pressure = 30 atm = 3,039,750 Pa; V2 is final volume = 2 L = 0.002 m^3; V1 is
initial volume = 7.20 L = 0.0072 m^3; while ΔH is the heat = -74,400 J (heat
released so negative)
Therefore:
ΔU =-3,039,750 Pa * (0.002 m^3 - 0.0072 m^3) + (- 74,400
J)
<span>ΔU = - 58,593.3 J = - 58.6 kJ</span>
Answer:
"To ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance."
Explanation:
Hello,
The OSHA -Occupational Safety and Health Administration- is an agency of the United States Department of Labo signed into law on December 29, 1970. It was created to prevent workers from being killed or seriously harmed at work. The law requires that employers provide their employees with working conditions that are free of known dangers.
The mission is "to ensure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance."
Best regards.
Boiling water relies on convection.
I think (1) redox reaction is the correct answer.
