Potentially useluluseless information R . 0 08206 OL'atrny(mol%) R-8314 Jamork) 760 mm Hg·760 torr-100 am-101 kPa ms 3RT/M)2 The volume of the container increases by about 7% The volume ofthe container is cut in half. No prediction can be made without knowing the exact pressure and number of moles of gas The volume of the container would decrease by about 7% O The volume of the container doubles 1.00000 poi QUESTION 18 hole in a close-packed crystal structure that is generaly of larger size and has a coorinaltion number of 6 is called a/an coordination number of 4 is called alan An alloy that is made when another type of atom replaces some atoms in the crystal structure is called alan caled alan_ hole.

You have the ideal gas equation
P V = n R T as you can see the temperature is directly proportional to the pressure, if the temperature increases then the pressure will increase.
the right answer is a
the volume will increase so b c an d are wrong
the last one cannot be possible the temperature needs to be the double amount of kelvin degrees not the double amount of celsius degrees
