<u>Answer:</u> The correct answer is 200°C

<u>Explanation:</u>

Boiling point is defined as the temperature at which liquid state starts to convert into gaseous state. It is an intensive property.

Intensive property is defined as the property which does not depend upon the amount of substance. It remains same.

Extensive property is defined as the property which depends upon the amount of substance. Its value changes as the amount of substance changes.

Boiling point of a substance will not change for given mass of substances.

Boiling point of water = 100°C

Boiling point of soybean oil = 300°C

From the given table:

Value of M = 100°C

Value of N = 300°C

So, the difference in the values of N and M = (300 - 100)°C= 200°C

Hence, the correct answer is 200°C

I am probably wrong but I would think 900. I wouldn’t submit that without somebody backing me up though.

Entropy means that _________.A. the quantity of usable energy declines with each transformationB. energy can be neither created
son4ous [18]

Answer:

answer A

Explanation:

A) the quantity of usable energy declines with each transformation → True . Since the entropy increases , the amount of energy that can not be converted to useful energy increases and since the total amount of energy is conserved, the quantity of useful energy decreases.

B) energy can be neither created nor destroyed → False in the context of entropy , since the energy is conserved regardless of the changes in entropy (First law → conservation of energy vs second law → increase of entropy)

C)  life should be impossible → False . Since the second law states that the entropy of the <u>universe </u>increases with time . Then the system (life) can experience a decrease in entropy  at the expense of a larger increase in entropy of the surroundings ( so the net increase is positive)

D) it is not possible to observe an increase in molecular organisation → False . Same as C. A system  can experience a decrease in entropy at the expense of a larger increase in entropy of the surroundings ( so the net increase is positive)

The equation shown represents cellular respiration. Glucose + X → Y + Water + Energy What do X and Y most likely represent? X re
777dan777 [17]

Answer:

X represents oxygen and Y represents carbon dioxide.

Explanation:

Because in respiration, you consume oxygen and make carbon dioxide whereas, in photosynthesis, the equation is reversed and you use carbon dioxide and make oxygen and glucose.

2) 183 cg =<br> kg<br> 5<br> .00183 kg<br> 0.0183 kg<br> .183 kg<br> 3) 0.25 kg =<br> g
OlgaM077 [116]

Answer:

183 cg = 0.00183 kg

0.25 kg = 250 g

Explanation:

Use conversion factors. 1kg is equal to 1 x 10^5 cg (100000) and 1 kg is equal to 1 x 10^3 grams (1000 grams).
