Boyle's Law states that when a sample of gas is compressed at a constant temperature, the pressure P and volume V satisfy the eq

____ [38]

Answer:

The gas is decreasing at a rate of 50 cubic centimeters per minute.

Explanation:

The Boyle's Law is represented by the following expression:

$P\cdot V = k$ (1)

Where:

$P$ - Pressure, in kilopascals.

$V$ - Volume, in cubic centimeters.

$k$ - Proportionality constant, in kilopascal-cubic centimeters.

By definitions of rate of change and implicit differentiation, we derive the following differential equation:

$\dot P \cdot V + P\cdot \dot V = 0$ (2)

Where:

$\dot P$ - Rate of change of the pressure, in kilopascals per minute.

$\dot V$ - Rate of change of the volume, in cubic centimeters per minute.

Then, we clear the rate of change of the volume within (2):

$P\cdot \dot V = -\dot P\cdot V$

$\dot V = -\left(\frac{\dot P}{P} \right) \cdot V$

If we know that $P = 180\,kPa$ , $\dot P = 30\,\frac{kPa}{min}$ and $V = 300\,cm^{3}$ , then the rate of change of the volume is:

$\dot V = -\left(\frac{\dot P}{P} \right) \cdot V$

$\dot V = -50\,\frac{cm^{3}}{min}$

The gas is decreasing at a rate of 50 cubic centimeters per minute.

What kind of feature results from the convergence of two oceanic plates?

Liono4ka [1.6K]

Answer: When a convergent boundary occurs between two oceanic plates, one of those plates will subduct beneath the other. Normally the older plate will subduct because of its higher density. The subducting plate is heated as it is forced deeper into the mantle, and at a depth of about 100 miles (150 km) the plate begins to melt.

what is the heat of a reaction, in joules, with a total reaction mixture volume of 67.9 ml if the reaction causes a temperature

Ahat [919]

The heat of reaction is 1.8 KJ. A calorimeter is a device used in calorimetry, a procedure for calculating heat capacity and measuring the heat of chemical processes or other physical changes.

<h3>How to calculate calorimeter?</h3>

A calorimeter is a device used in calorimetry, a procedure for calculating heat capacity and measuring the heat of chemical processes or other physical changes.

Among the most popular kinds are differential scanning calorimeters, isothermal micro calorimeters, titration calorimeters, and accelerated rate calorimeters.

Calorimeter, a tool for estimating a material's heat capacity and measuring the heat produced during a mechanical, electrical, or chemical reaction. bomb thermometer.

Volume of water = 67.9 mL

Since the density of water is 1.00 g/mL

Density = mass/volume

Mass of water = Density × volume

Mass of water = 1 g/mL × 67.9 mL

Mass of water = 67.9g or 0.0679 Kg

Temperature change = 6.5 oC

Specific heat capacity of water= 4.184 J/Kg

From;

H = mcθ

m = mass of water

c = heat capacity of water

θ = temperature rise

Substituting values;

H = 0.0679 Kg × 4.184 J/Kg × 6.5 oC

H = 1.8 KJ
