Answer:

The freezing point is the temperature at which a liquid turns to a solid. ... This temperature is referred to as the melting point when temperatures rise above 32°F (0°C), causing ice to melt and change state from a solid to a liquid (water), as happened with the cup of crushed ice at room temperature.

I don't really know what your question is asking so I am just going to list a few facts that I think might be what you are asking.

Ice turning into water is a physical change.  The ice is undergoing the process of melting which does not change it chemically (ice and water are chemically identical in the sense that they are both composed of H₂O molecules) and the only difference between water and ice is that water molecules have a higher average amount of energy than the ice molecules do.  When a substance melts, the molecules within the substance gain energy (in the form of heat) which allows them to break the intermolecular forces keeping them together.  Since the melting of ice requires energy, the process is endothermic which means that the ice had to get energy from its surroundings and that water has more energy than ice does as a result of the process (ΔH is positive).

I hope that helps.  Let me know in the comments if anything is unclear or if I did not answer your question.

Why is the cellulose part of human diet​
Luden [163]

Answer:

Cellulose stimulates the work of intestines and increases their discharge.

Explanation:

Cellulose is a polysaccharide made of glucose polymers, which build plant fibers. Because of this, the plants possess their firmness.

Humans do not digest cellulose because they do not possess certain enzymes, but it is useful for their digestion because it stimulates the work of the intestines.

Cellulose enhances intestinal peristalsis. Peristalsis is series of contractions that allow the progressive movement of food through the digestive tract.

My barometer is reading 1253 torr. What is the pressure in mmHg?
kobusy [5.1K]

Answer:

The pressure in mmHg is 1253 (option C)

Explanation:

Two quantities are directly proportional if when multiplying or dividing one of them by a number, the other is multiplied or divided by that number. In other words, the magnitudes are directly proportional when one magnitude increases and so does the other in the same proportion; or when one magnitude decreases and so does the other in the same proportion.

The rule of three or is a way of solving proportionality problems between three known values ​​and an unknown value, which can be applied to directly proportional quantities as follows:

a ⇒ b

c ⇒ x

So x=\frac{c*b}{a}

where a, b and c are data and x is the unknown value to be calculated.

In this case, knowing that 1 Torr = 1 mmHg, the rule of three can be applied as follows: if 1 torr is equal to 1 mmHg, 1253 torr is equal to how many mmHg?

pressure=\frac{1253 torr*1 mmHg}{1 torr}

pressure= 1253 mmHg

<u><em>The pressure in mmHg is 1253 (option C)</em></u>
