A certain amount of gas at 25 C and at a pressure of 0.800 atm is contained in a glass vessel. Suppose that the vessel can withstand a pressure of 2.00 atm. How high can you raise the temperature of the gas without bursting the vessel?

a. P1 / T1 = P2 / T2

b. so .8/298=2/T2

c. which equals 745 K

Respuesta :

Answer :  745 K high you can raise the temperature of the gas without bursting the vessel.

Explanation :

Gay-Lussac's Law : It is defined as the pressure of the gas is directly proportional to the temperature of the gas at constant volume and number of moles.

[tex]P\propto T[/tex]

or,

[tex]\frac{P_1}{T_1}=\frac{P_2}{T_2}[/tex]

where,

[tex]P_1[/tex] = initial pressure of gas = 0.800 atm

[tex]P_2[/tex] = final pressure of gas = 2.00 atm

[tex]T_1[/tex] = initial temperature of gas = [tex]25^oC=273+25=298K[/tex]

[tex]T_2[/tex] = final temperature of gas = ?

Now put all the given values in the above equation, we get:

[tex]\frac{0.800atm}{298K}=\frac{2.00atm}{T_2}[/tex]

[tex]T_2=745K[/tex]

Therefore, the final temperature of the gas is 745 K

Answer:

=745 Kelvin

Explanation:

  • According to the pressure law the relationship between the pressure and absolute temperature of a  gas at a constant volume is directly proportional.
  • An increase in temperature causes a corresponding increase in pressure at a constant volume.

That is;

[tex]P\alpha T[/tex]

Mathematically;

[tex]P = kT\\(Constant)k =\frac{P}{T} \\[/tex]

When there are two varying conditions;

[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]

In this case;

P1 = 0.8 atm

T1 = 25+273 = 298 K

P2 =2.00 atm

T2= ?

Therefore;

[tex]T2= \frac{P2T1}{P1}[/tex]

[tex]T2= \frac{(2)(298)}{0.8}[/tex]

[tex]= 745 K[/tex]

Therefore, the temperature can be raised up to 745 kelvin without bursting vessel.
