what is the effect of the following on the volume of 1 mol of an ideal gas?

a. the pressure is reduced by a factor of 4 (at constant t)
b. the pressure changes from 760 torr to 202 kpa, and the temp. changes from 37degrees c to 155 degrees kelvin.
c. the temp changes from 305 degrees kelvin to 32 degrees c, and the pressure changes from 2 atm to 101 kpa?

I am pretty sure that the effect on the volume of 1 mol of an ideal gas is being revelesd by the option : B. The pressure changes from 760 torr to 202 kPa, and the temp. changes from 37degrees C to 155 degrees kelvin. I choose this one because you have to use ideal gas law - V= nRT/P and you will see the doubled pressure in here : 760 torr= 1atm and 202kPa = 2 atm.
Do hope it helps! Regards.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

Ithink that the answer is b
