15L tank of gas is contained at a high pressure of 8.20 •10 ^4 torr. The tank is opened and the gas expands into an empty chamber with a volume of 6• 10^4 L

The question is incomplete. The complete question is:

15L tank of gas is contained at a high pressure of . The tank is opened and the gas expands into an empty chamber with a volume of

where,

are initial pressure and volume.

are final pressure and volume.

We are given:

Putting values in above equation, we get:

Thus new pressure will be

indium, and thallium have three electrons i think

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
