A graph of gas pressure versus the number of particles in a container is a straight line. Which other relationship will have a similar graph? volume versus pressure, because they are also directly proportional volume versus temperature, because they are also directly proportional volume versus pressure, because they are also inversely proportional volume versus temperature, because they are also inversely proportional

Answers

Answer:

Explanation:

gitcy is good for your spleen

The other relationship that will have a similar graph is volume versus temperature, because they are also directly proportional according to Charles's Law.

What is Charles's Law?

Charles's Law is a gas law that states that the volume of a fixed mass of gas at a constant pressure is directly proportional to its absolute temperature.

This means that as the temperature of a gas increases, the volume of the gas will also increase proportionally, and as the temperature of a gas decreases, the volume of the gas will decrease proportionally.

Therefore, if a graph of gas pressure versus the number of particles in a container is a straight line, a graph of volume versus temperature will have a similar shape and be directly proportional, because they are both affected by changes in temperature.

What volume in liters will 50.0g CO occupy? please show work.

Answers

Answer:

40.0L is the volume the CO occupy

Explanation:

To solve this question we must assume the gas is at STP. To find the volume of a gas using the moles, temperature and pressure of the gas we have to use:

PV = nRT

V = nRT / P

Where V is volume in liters

n are moles of the gas -Molar mass CO: 28g/mol-

50.0g * (1mol / 28g) = 1.786 moles CO

R is gas constant = 0.082atmL/molK

T is absolute temperature = 273.15K at STP

P is pressure = 1atm at STP

Replacing:

V = 1.786moles*0.082atmL/molK*273.15K / 1atm

V = 40.0L is the volume the CO occupy

How many moles of Manganese there in are 5.76 x 10(15) atoms of Mn?
How many moles of sodium chloride are in a 431.6 g sample of NaCl?

Answers

Answer:

1. 9.57 × 10^-9 moles.

2. 7.38mol

Explanation:

1.) To find the number of moles there are in the number of particles in an atom, we divide the number of particles (nA) by Avagadro's constant (6.02 × 10^23)

Hence, to find the number of moles (n) of Manganese (Mn), we say:

5.76 x 10^15 atoms ÷ 6.02 × 10^23

5.76/6.02 × 10^(15-23)

= 0.957 × 10^-8

= 9.57 × 10^-9 moles.

2.) Mole = mass/molar mass

Molar mass of sodium chloride (NaCl) = 23 + 35.5

= 58.5g/mol

mole = 431.6 g ÷ 58.5g/mol

mole = 7.38mol

How do rock transformations on Venus and Earth indicate the planetary similarities between the two planets?

Answers

Answer:

Both the Earth and Venus show the appearance of igneous rocks due to the cooling of the magma.

Explanation:

As we know, ignea rock is the first step in the transformation of rocks. This rock is formed by the overflow of terrestrial magma which, upon cooling, turns into ignea rock, which will undergo metamorphism and transform into metamorphic rock, which will continue to undergo metamorphosis until it becomes the other rocks that complete the rock cycle. This is a terrestrial process that can be found on Venus, which also presents the cooling of magma in the formation of ignea rock, which will undergo metamorphism, transforming into other rocks, the way it occurs on Earth.

A sample of air starts at STP. The volume and moles remains the same, what happens to the pressure if the temperature changes to 317 K?
show steps

Answers

Answer:

Pressure increases to 1.16 atm if the temperature changes to 317 K.

Explanation:

The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C (or 273 K) are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.

On the other hand, Gay Lussac's law indicates that when there is a constant volume, as the temperature increases, the pressure of the gas increases. And when the temperature is decreased, the pressure of the gas decreases. This law mathematically indicates that the quotient between pressure and temperature is constant:

[tex]\frac{P}{T}=k[/tex]

Studying an initial state 1 and a final state 2 is fulfilled:

[tex]\frac{P1}{T1}=\frac{P2}{T2}[/tex]

In this case:

P1= 1 atmT1= 0 C= 273 KP2= ?T2= 317 K

Replacing:

[tex]\frac{1 atm}{273 K} =\frac{P2}{317 K}[/tex]

Solving:

[tex]P2=317 K*\frac{1 atm}{273 K}[/tex]

P2= 1.16 atm

Pressure increases to 1.16 atm if the temperature changes to 317 K.

What term describes the temperature at which a substance can change state from a liquid to a gas?
A. Boiling point
B. Melting point
C. Freezing point
D. Specific heat

Answers

Option A. Boiling point.

Explanation:

When you heat the water, the water gets converts into gaseous form.

As you know that water is in liquid form. So, when you heat the water, the water molecules absorbs the heat and get dispersed from one another molecules. i.e., molecules go far from the other molecules as they absorbed heat.

The term describes the temperature at which a substance can change state from a liquid to a gas, is boiling point. Therefore, option A is correct.

What is boiling point ?

The temperature at which a liquid's vapor pressure equals the pressure around it and the liquid transforms into a vapor is known as the boiling point of a substance. A liquid's boiling point varies depending on the atmospheric pressure in the area.

Boiling point and saturation temperature are synonyms. Sometimes the measurement's pressure serves as a definition for the boiling point. The International Union of Pure and Applied Chemistry was founded in 1982.

The boiling point of a sample can be calculated using a number of techniques, such as distillation, reflux, and a Thiele tube. The simplest approach makes use of a Thiele tube and has the benefit of requiring less than 0.5mL of substance.

Thus, option A is correct.

A gas occupies 12.3 L at a temperature of 40.0 K. What is the volume when the temperature is increased to 60.0 K?

Answers

Answer:

the volume is 18.45 L

Explanation:

The computation of the volume when the temperature is increased to 60.0 K is shown below:

Since the gas occupied 12.3 L at a temperature of 40.0 k

And, the volume when the new temperature is 60.0 k

So, the volume is

= 60.0 k × 12.3 L ÷ 40.0 k

= 18.45 L

hence, the volume is 18.45 L

The excessive pumping of water through well is the major reason for the drop of ground water level. The nearby farms over use water and pumps from undergrounds.

What is underground water?

Water beneath the earth surface is called ground water. The storage of ground water is a very important in all areas to sustain our need for water and it must be maintained pure without the presence of overdose of heavy metals and other impurities.

Reduction in the level of ground water storage is a serious issue that might leads to a scenario where the drinking water is not sufficient. The uncontrolled use of pump water by factories, industries and farms results in the drop of ground water level.

The nearby farms might pumping water from sources uncontrollably in the area. That is the main reason of dropping in ground water level. Hence, option B is correct.
