The answer is:

Hence, the new pressure will be 2.07 atm.

$P_{2}=2.07atm$

Since we know that the gas is inside of a rigid container, meaning that the volume will be kept constant, we can solve the problem using the Gay-Lussac's Law.

The the Gay-Lussac's Law establishes that when an ideal gas is kept at the same volume, the pressure and the temperature will be proportional.

We need to pay special attention when we are working with the Gay-Lussac's Law since its equaitons works with absolute temperatures (Kelvin ), so, if we are working with relative temperatures such as Celsius degrees or Fahrenheit degrees, we need to convert the temperatures to Kelvin.

We can convert from Celsius degrees to Kelvin using the following formula:

$Temperature(K)=Temperature(C\°)+273$

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

$\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}$

Also, we are given the following information:

$T_{1}=30\° \\P_{1}=2atm\\T_{2}=40\°$

Therefore, converting the temperature to Kelvin, we have:

$T_{1}=30C\°=30+273K=303K\\\\T_{1}=40C\°=40+273K=313K\\$

Now, calculating we have:

$\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}$

$P_{2}=\frac{P_{1}}{T_{1}}*T_{2}\\\\P_{2}=\frac{2atm}{303K}*313K=2.07atm$

Hence, the new pressure will be 2.07 atm.

$P_{2}=2.07atm$

Have a nice day!

Which of the following are characteristics of stratovolcanoes? Select all that apply.

qaws [65]

Answer:

More common near convergent boundaries

Explosive Eruptions

Low Viscosity Magma

Explanation:

Hot spots like hawaii are better known for shield volcanoes. The magma is high viscosity which causes them to build pressure before erupting, leading to explosive eruptions.

A standard room temperature and pressure, most of the elements on the periodic table are

Maslowich

Answer:

Solids

Explanation:

At standard room temperature and pressure, most of the elements are solids.

Just a few of the elements are liquids and gases at this temperature.

The periodic table is made up of metals, metalloids and non-metals. Most of these substances are actually solid.

Some non-metals are gaseous at standard room temperature.
