Can someone please help me figure out the following exampleproblems? 1)While under constant pressure, the temperature of 716 mL ofa gas is changed from 50 °C to 164 °C. What is the new gasvolume?
2)If a 432 mL sample of gas at 177 °C is allowed to expand(at constant pressure) to a volume of 593 mL, what will be the newtemperature (in °C)?

Explanation / Answer

1) Charles law : Vi/Ti = Vf/ Tf   at constant p and    n       Given: Vi =716mL   Ti = 50°C                   Vf=?            Tf = 164 °C                                             Vf = (716mL/50°C)*164 °C                                = 2348.48mL Hence, volume changed to 2348.48mL 2) Given : Vi = 432mL    Ti =177 °C                    Vf = 593mL   Tf= ?                                                      Tf = (177 °C / 432mL)*593mL                                   = 242.96 °C Hence, volume changed to 2348.48mL 2) Given : Vi = 432mL    Ti =177 °C                    Vf = 593mL   Tf= ?                                                      Tf = (177 °C / 432mL)*593mL                                   = 242.96 °C
