A gas in a rigid container at 25C has a pressure of .96atm. A change in temperature causes the pressure to increase to 1.25 atm.

mars1129 [50]

<h2>Hello!</h2>

The answer is:

The new temperature of the gas is equal to 388.22 K

Since we have a rigid container, we can safely assume that the volume is kept constant.

To solve the problem, we need to use the Gay Lussac's Law, which states that the pressure and the volume of an ideal gas are proportional when the volume is kept constant.

Also, we need to remember that Gay Lussac's Law works with absolute temperature, so, we need to convert the given temperature (in celsius degrees) to Kelvin.

$T(K)=273.15 + T(\°C)\\\\T(K)=273.15 +25=298.15K$

So, using the Gay Lussac's equation, we have:

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

Where,

$P_1$ is equal to the first pressure.

$T_1$ is equal to the first temperature.

$P_2$ is equal to the new pressure.

$T_2$ is equal to the new temperature.

We are given the following information:

$P_1=0.96atm$

$T_1=298.15K$

$P_2=1.25atm$

Then, substituting and calculating, we have:

$T_2=P_2*\frac{T_1}{P_1}\\\\T_2=1.25atm*\frac{298.15K}{0.96atm}=388.22K$

Hence, the new temperature of the gas is equal to 388.22 K.

Have a nice day!

If the Bunsen burner gave a luminous flame and some soot was deposited on

Harlamova29_29 [7]

Explanation:

If bunsen burner gave a luminous flame then there will deposition of soot at the bottom of the test tube which is actually pure carbon.

This deposition of soot actually depicts that there is incomplete combustion reaction that has taken place.

Also, the deposition of soot will provide a limited supply of oxygen to the reaction that has been calculated.

Therefore, in order to avoid any formation of soot it is advisable to adjust the burner flame till it produces a blue flame.
