A steel cylinder has a pressure of 550 torr at 177 degrees Celsius. What will be the pressure if the temperature is decreased by
Schach [20]

Answer:

P_2=507.7torr

Explanation:

Hello there!

In this case, when we have a gas that is undergoing a change in both pressure and temperature, we utilize the Gay-Lussac's equation as shown below:

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

Thus, since we are given the initial pressure and temperature and the final temperature, we can compute the final pressure as shown below:

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

So we plug in, by making sure the temperatures are in kelvins, to obtain:

P_2=\frac{550torr}{(117+273)K}*(87+273)K\\\\P_2=507.7torr

Best regards!

Brrunno [24]
The symbol for the hydronium ion is H3O+.
An hydronium ion is usually formed when an acid is present in water. The hydronium ion is made up of three atoms of hydrogen and one atom of oxygen, thus an hydronium ion is a water molecule which has gained an extra positive hydrogen ion.
