What is the pressure of the gas in this mercury manometer if h = 83 mm and atmospheric pressure is 769 mmhg?

The total pressure of a gas is equal to the sum of the gauge pressure and the atmospheric pressure. The gauge pressure is the pressure measured in a device. In this case, it will be the pressure measure from the mercury manometer. The atmospheric pressure is the pressure of the …

Use the equation where p = pressure and V = volume. What happens to the pressure as the volume approaches 0? Explain your reasoning.

Answer:-  The pressure ‘p’ will be infinity at volume ‘V’=0. Explanation:- The given equation :- where p is a rational function dependent on V. A rational function is undefined for denominator = 0. In the given function V is the denominator , if V=0 then the function will be undefined. …

Think about an igneous rock at the top of a mountain. If this rock went through the whole rock cycle, number the steps that would follow. 1. Step 1 Regolith is dumped into some type of reservoir, usually water, by deposition. 2. Step 2 Metamorphic rock begins to melt back into magma. 3. Step 3 Regolith is transported or eroded by rain or wind. 4. Step 4 Rock is broken down into regolith by weathering. 5. Step 5 Layers deposited begin to compact and cement together to form sedimentary rock. 6. Step 6 Sedimentary rock is buried deeper into the earth’s crust. The intense heat and pressure begins metamorphism and the rock turns into metamorphic rock. 7. Step 7 Magma is resurfaced from volcanic activity, cools, and becomes igneous rock.

Answer: The correct sequence according to the question is steps- 4→1→3→5→6→2→7. Explanation: The given steps show that how the rocks are recycled from one form to another form due to certain factors like weathering over geological time scale which was explained by James Hutton and he termed this concept as …

PLEASE HELP Mr. Utterson the lawyer was a man of a rugged countenance, that was never lighted by a smile; cold, scanty and embarrassed in discourse; backward in sentiment; lean, long, dusty, dreary, and yet somehow lovable. At friendly meetings, and when the wine was to his taste, something eminently human beaconed from his eye; something indeed which never found its way into his talk, but which spoke not only in these silent symbols of the after-dinner face, but more often and loudly in the acts of his life. He was austere with himself; drank gin when he was alone, to mortify a taste for vintages; and though he enjoyed the theatre, had not crossed the doors of one for twenty years. But he had an approved tolerance for others; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds; and in any extremity inclined to help rather than to reprove. "I incline to, Cain's heresy*," he used to say. "I let my brother go to the devil in his quaintly 'own way.'" In this character, it was frequently his fortune to be the last reputable acquaintance and the last good influence in the lives of down-going men. And to such as these, so long as they came about his chambers, he never marked a shade of change in his demeanour. No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature. It is the mark of a modest man to accept his friendly circle ready-made from the hands of opportunity; and that was the lawyer's way. His friends were those of his own blood or those whom he had known the longest; his affections, like ivy, were the growth of time, they implied no aptness in the object. Hence, no doubt, the bond that united him to Mr. Richard Enfield, his distant kinsman, the well-known man about town. It was a nut to crack for many, what these two could see in each other, or what subject they could find in common. It was reported by those who encountered them in their Sunday walks, that they said nothing, looked singularly dull, and would hail with obvious relief the appearance of a friend. For all that, the two men put the greatest store by these excursions, counted them the chief jewel of each week, and not only set aside occasions of pleasure, but even resisted the calls of business, that they might enjoy them uninterrupted. *The biblical story of Cain and Abel is a story about two brothers who gave offerings to God. Abel’s offering was accepted by God, but Cain’s was not. Jealous, Cain killed his brother. When God asked Cain where Abel was, Cain said, “Am I my brother’s keeper?” By saying this, Cain implied that what his brother did was his own business. (Genesis 4:1-16) What is significant about “Cain’s heresy” in this passage? A.It shows that Mr. Utterson is a deeply religious and righteous person. B.It shows that Mr. Utterson tries not to judge others or get in their business. C.It shows the Mr. Utterson wants to steal from other people’s businesses. D.It shows that Mr. Utterson does not believe in any kind of religion at all.

A gas has a volume of 25 ml at a pressure of 100 kpa. what will the new volume of the gas be at a pressure of 150 kpa if the temperature remains constant?

This problem is to apply Roult’s Law. Roult’s Law states that the vapor pressure, p, of a solution of a non-volatile solute is equal to the vapor pressure of the pure solvent, Po solv, times the mole fraction of the solvent, Xsolv p = Xsolv * Po sol X solv …

An oxygen bottle containing a fixed volume of o2 gas has a pressure of 800.00 mm hg and a temperature of 295k. if the bottle is heated to 328k what will the pressure of o2 gas be within the bottle and which law will you use to solve it?

The equation for how temperature changes the resistance R is:  R=R₀(1+α(T-T₀)), where R₀ is the resistance at T₀=20°C, T is the temperature for which we want to calculate the resistance and α is the temperature coefficient for resistance.  The resistance of the copper wire increases by 18% or by 0.18, so the …
