Answer:
a. 123.9°C
b.
c.
Explanation:
Hello, I'm attaching a picture with the numerical development of this exercise.
a. Since the steam is overheated vapour, the specific volume is gotten from the corresponding table. Then, as it became a saturated vapour, we look for the interval in which the same volume of state 1 is, then we interpolate and get the temperature.
b. Now, at 80°C, since it is about a rigid tank (constant volume for every thermodynamic process), the specific volume of the mixture is 0.79645 m^3/kg as well, so the specific volume for the liquid and the vapour are taken into account to get the quality of 0.234.
c. Now,since this is an isocoric process, the heat transfer per kg of steam is computed as the difference in the internal energy, considering the initial condition (showed in a. part) and the final one computed here.
** The thermodynamic data were obtained from Cengel's thermodynamics book 7th edition.
Best regards.
"Naturally occurring, inorganic substance" factor is not a characteristic of a mineral.
<u>Answer:</u> Option C
<u>Explanation:</u>
A mineral is overall a solid chemical substance that naturally occurs in pure form. Due to the combination of minerals within the rocks, minerals are most strongly associated with rocks.
Substances that exist only in living organisms are generally removed however some minerals are often biogenic like calcite or in the sense of chemistry like mellite are organic compounds. In addition, living creatures also synthesize inorganic minerals like such as hydroxylapatite, which also exist in the rocks.
Homeostasis is defined as a constant, steady environment despite external changes, such as exercise. Exercise affects your body temperature, blood oxygen levels, sugar levels and hydration – all properties necessary for your survival. Your body uses an automatic feedback system to preserve normal temperature and water levels, so you can keep exercising. Eat properly and drink plenty of fluids to help your body maintain homeostasis. You need to drink and eat properly.
Answer:
.5 gm / ml
Explanation:
Density is defined as mass/ volume
so density of this substance is 5 gm / 10 ml = .5 gm/ ml
