Considering the Boyle's law,the volume of the new sample of gas will be 19.778 atm.

<h3>Boyle's law</h3>

Boyle's law establishes the relationship between the pressure and the volume of a gas when the temperature is constant. This law says that the pressure of a gas in a closed container is inversely proportional to the volume of the container: if the pressure increases, the volume decreases, while if the pressure decreases, the volume increases.

Boyle's law is expressed mathematically as:

P×V=k

Having an initial state 1 and a final state 2, the following is true:

P1×V1=P2×V2

<h3>New volume</h3>

In this case, you know:

P1= 1.78 atm
V1= 11 L
P2= 0.99 atm
V2= ?

Replacing in Boyle's law:

1.78 atm× 11 L=0.99 atm× V2

Solving:

(1.78 atm× 11 L)÷ 0.99 atm=V2

Finally, the volume of the new sample of gas will be 19.778 atm.

Answer:

The Avogadro's Number will reduce in value

Explanation:

From the question we are told that

The current pass through the short circuit is $0.1 *I$

Here I is the total current

Generally Avogadro's Number is mathematically represented as

$N_A = \frac{Q}{ 2 * n * e}$

Here Q is the charge which is mathematically represented as

$Q = It$

n is number of moles

e is the charge on an electron

$N_A = \frac{I * t }{ 2 * n * e}$

Now when the current decreases from 100% to 90% due to the short circuit . this will also reduce the no of moles of metal dissolved hence from the equation we see that the Avogadro's Number will reduce

3.50 liters of a gas at 727.0 K will occupy how many liters at 153.0 K?

miv72 [106K]

Answer:

0.737 L

Explanation:

Charles law states for a fixed amount of gas, volume of the gas is directly proportional to the absolute temperature of the gas at constant pressure

we can use the following equation

V1/T1 = V2/T2

where V1 is volume and T1 is temperature at first instance

V2 is volume and T2 is temperature at the second instance
