1) At 0oc and 1ATM pressure the volume of a gas is 546, calculate at 27oc. [600ml]
2) A five-lit vessel containing a gas at 6atm pressure is connected to another empty vessel of volume 15lit. find the pressure exerted by the gas in the new system.[1.5atm]
3) A gas if volume 200cc is kept in a container at 102pa and 27oc. The pressure if the gas is increase to 103pa and temp is kept constant. Calculate the volume of the gas. [20cc]
4) At 25oc and 2atm pressure a gas occupies 10lit volume. At what temp and 0.5atm pressure the same gas occupies 80 lit volume. [same]
5) At 27oc and 1atm pressure the volume of a gas is 10lit. calculate the volume of same gas at 927oc and 1atm pressure [40lit]
6) At constant pressure gas at –33oc is heated to 127oc. Find the percentage increase in volume of gas, [34% to 66%= 32%]
7) At 27oc and 1atm pressure the volume of the gas is 10lit. At what temperature at same pressure the volume of the gas will be doubled. [327oc]
8) At 27oc gas was compressed to half its volume. To what temperature must it be heated original volume? [327oc]
9) At what temperature, the volume of a gas at 0oc will be doubled. [273oc]
10) At –123oc the volume of a gas is 5lit. what is the volume of same gas at constant pressure and 327oc. [20lit]
11) At 819oc the volume of a gas is 6lit.at what temperature the volume of same gas is 3lit. [273oc]
12) A flask has a capacity of 500ml. how much of in expelled from the flask if it is heated from 27oc to 37oc. [1.5ml]
13) A gas was compressed to ¼ of its volume at 303k. to what temperature it should be heated so that its volume increases to double of its original gas. [2151oc]
