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 with
sp2606 [1]

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;

P\alpha T

Mathematically;

P = kT\\(Constant)k =\frac{P}{T} \\

When there are two varying conditions;

\frac{P1}{T1} =\frac{P2}{T2}

In this case;

P1 = 0.8 atm

T1 = 25+273 = 298 K

P2 =2.00 atm

T2= ?

Therefore;

T2= \frac{P2T1}{P1}

T2= \frac{(2)(298)}{0.8}

= 745 K

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