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.

Which area should have the lowest temperatures?<br><br> A. 1<br><br> B.2 <br><br> C.3 <br><br> D.4
pochemuha

Answer:

A. 1

Explanation:

The higher you get in the atmosphere the cooler the temperature will be. The reason it's actually colder is because, as you go up in the atmosphere, the Earth's atmosphere feels less pressure the higher up you go. So as the gas in the atmosphere rises it feels less pressure, which makes it expand.

Hope this Help :)
