correct the following examples of gasses to standard temperature. (assume pressure is constant)(STP stands for standard temp and pressure which is 273K and 101kPa, you do no have to think about the pressure for these four but on the last three you will have to so T2 is 273K and P2 will be 101.3kPa.

1. 1620cm^3 at 15.0 C
2. 12.83 L at 230K
3. 154.8dm^3 at 110K
4. 1255cm^3 at 478.0 C

Reason through this.

1. You have 1620 cc gas at 15 C (273 + 15 = 288 K) and you want to know what it will be at 273. You know that T is getting smaller, you know V will get smaller so you multiply by a factor using temperature that will give you a smaller number; i.e.,
1620 x (273/288) = ?

2,3,4 are done the same way. Remember Charles' Law. T goes up so does V; T goes down so does V.
