Answer:

The new volume will be  

0.7 L

Explanation:

This is an illustration of Charles' law, some of the time called the temperature-volume law. It expresses that the volume of a gas is straightforwardly corresponding to the Kelvin temperature, while pressing factor and sum are held steady.  The condition is  V  1  T  1  =  V  2  T  2  , where  V  is volume and  T  is temperature in Kelvins.  Known  V  1  =  0.5 L  T  1  =  20  ∘  C  +  273.15  =  293 K  T  2  =  150  ∘  C  +  273.15  =  423 K  Obscure  V  2  Arrangement  Revise the condition to confine  V  2  . Substitute the known qualities into the condition and address.  V  2  =  V  1  T  2  T  1  V  2  =  (  0.5  L  ×  423  K  )  293  K  =  0.7 L  adjusted to one huge figure

Answer:

Without the sun's energy, biological life would not be able to exist to decompose. Many microbes and fungi do their best work out of direct sunlight.

In an ecosystem, microbes make use of solar energy to decompose dead plant and animals.

Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.

Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.There are different types of ecosystems present.

[tex]\boxed {\boxed {\sf 4038.48 \ Joules}}[/tex]

Explanation:

Since we are given the mass, specific heat, and change in temperature, we should use this formula for heat:

[tex]q=mc\Delta T[/tex]

The substance's mass is 450.0 grams, the specific heat is 1.264 J/g°C, and the  change in temperature is 7.1 °C.

[tex]m= 450.0 \ g \\c= 1.264 \ J/g \textdegree C\\\Delta T= 7.1 \ \textdegree C[/tex]

Substitute the values into the formula.

[tex]q= (450.0 \ g)(1.264 \ J/g \textdegree C)(7.1 \ \textdegree C)[/tex]

Multiply the first 2 values together. The grams will cancel out.

[tex]q= 568.8 \ J/ \textdegree C (7.1 \ \textdegree C)[/tex]

Multiply again. This time, the degrees Celsius cancel out.

[tex]q= 4038.48 \ J[/tex]

4038.48 Joules of heat energy are released.

From Q = mcΔT, we can rearrange the equation to solve for mass, m = Q/cΔT. The specific heat capacity, c, of solid gold is 0.129 J/g °C. I'm assuming that the energy is given in joules, as it's not specified in the question as written.

m = Q/cΔT = (35.73 J)/(0.129 J/g °C)(40.85 °C - 0.85°C)

m = 6.92 g of gold was present  

The heat of the substance depends on the mass, specific heat, and temperature change of the system. The mass of gold that was present was, 6.92 g.

Mass of the substance in the thermodynamic system is the ratio of the heat to the product of the specific heat and the temperature change. It is given as,

[tex]\rm m = \rm \dfrac{Q}{c \Delta T}[/tex]

Given,

Heat (Q) = 35.73 J

Specific heat (c) = 0.129 J/g °C

Temperature change = 40 degrees celsius

Mass of gold is calculated as:

35.73 ÷ (0.129) (40) = 6.92 gm

Therefore, 6.92 gms of gold is present.

Answer:

5. Amplitude.

6. 344.8 meters/second

Explanation:

5. The energy is proportional to the amplitude is all I remember. Sorry :/ Been a long time since I took these classes.

6. Traveling to the wall & back is 200m

100 + 100 = 200m total traveled

The time is 0.58s so, we can use the speed formula to solve [ s = d/t ] where s = speed, d = distance, and t = time.

s = 200/0.58

s = 344.82758

I don’t know if they’ll have you round, but I would say the speed of the sound is 344.8 m/s.

Answer:

the volume that the gas occupy at 7.47 atm is  0.1564 liters

Explanation:

The computation of the volume that the gas occupy at 7.47 atm is shown below:

As we know that

P1V1 = P2V2

Now

V2 = P1V1 ÷ P2

= 2.05 atm × 0.570 liters ÷ 7.47 atm

= 0.1564 liters

Hence, the volume that the gas occupy at 7.47 atm is  0.1564 liters

So the same would be considered and relevant

Answer:

1.27atm is the pressure of the gas

Explanation:

Using combined gas law, we can find the pressure of a gas with the moles, temperature and volume of the gas. The formula is:

PV = nRT

P = nRT / V

Where P is pressure in atm

n are the moles of the gas: 4.6 moles

R is gas constant: 0.082tamL/molK

T is absolute temperature: 325K

V is volume: 96.8L

Replacing:

P = 4.6mol*0.082atmL/molK*325K / 96.8L

P = 1.27atm is the pressure of the gas

Answer: The density will decrease

Explanation: Heating a substance causes molecules to speed up and spread slightly further apart, occupying a larger volume that results in a decrease in density.

Answer:

The approximate mass of the weight required is 348.3 kg

Explanation:

The dimensions of the dead-weight gauge are;

The pressure up to which the dead-weight gauge measures, P = 3,000 bar

The diameter of the piston of the dead-weight gauge, D = 4 mm = 0.004 m

The dead-weight gauge pressure formula is given as follows;

Pressure, P = The weight applied, W ÷ The area the weight is applied, A

∴ The weight applied, W = P × A

Where;

P = Pressure

A = The area the weight is applied

W = The weight applied to the piston

The area the weight is applied, A = The area of the piston = π·D²/4

Where;

D = The diameter of the piston

∴ A = π × (0.004 m)²/4

When P = 3,00 bar, and A = π × (0.004 m)²/4, we have;

The weight applied, W = P × A

∴ W = 3,000 × π × (0.004 m)²/4 ≈ 3,769.9118 N

W ≈ 3,769.9118 N

W = m·g

Where;

m = The mass of weight

g = The acceleration due to gravity ≈ 9.81 m/s²

m = W/g

∴ m = 3,769.9118 N/(9.81 m/s²) ≈ 384.3 kg

The approximate mass of the weight required, m = 348.3 kg.

We started by Solving for the force and then the area of the piston, we then applied the formula for force using the constant for acceleration due to gravity and the mass was found to be 384.34 kg

Given Data

Pressure = 3000 bar

Diameter = 4mm

Let us convert bar to N/mm^2

1 bar = 0.1 N/mm^2

3000 bar = x N/mm^2

= 0.1*3000

= 300 N/mm^2

We know that pressure P = Force/Area

Let us find the area of the piston

Area = πd^2/4

Area = 3.142*4^2/4

Area = 3.142*16/4

Area = 50.272/4

Area = 12.568 mm^2

Let us find the force F

F = P*Area

F = 300*12.568

F = 3770.4 Newton

We know that Force = Mg

g = 9.81 m/s^2

Hence, m = F/g

m = 3770.4/9.81

m = 384.34 kg

The process in which Volume remains constant is called isochoric process.  

The process in which pressure remains constant is called isobaric process.

 The process in which no heat is gained or lost by the system, Hence heat remains constant is called as adiabatic process.

1 mole is equal to 1 moles CaCO3, or 100.0869 grams.

A mole is just a measuring scale. In reality, it's one of the International System of Units' seven foundation units (SI). When already-existing units are insufficient, new ones are created.

The mole is a SI unit that is used to quantify any quantity of a substance. The word "mole" is shortened to "mol".

A mole consists of precisely 6.022140761023 particles. The "particles" could be anything, from tiny things like electrons or atoms to enormous things like stars or elephants.

Therefore, 1 mole is equal to 1 moles CaCO3, or 100.0869 grams.
