Answer

The final volume, in milliliters, of the gas when the temperature changes to each of the following, if P and n do not change :

a. 1833.3 mL

b.13566.6 mL

c.-832.5 mL

d.-1100 mL

1Part(a) Step 1: Given information

We need to find that final volume, in milliliters, of the gas when the temperature changes to each of the following, if Pressure and amount do not change. 

2Part(a) Step 2: Explanation

By using charles law , we get ;

V2=V1×T2T1=2500×5575=1833.3 mL

3Part(b) Step 1: Given information

We need to find that final volume, in milliliters, of the gas when the temperature changes to each of the following, if Pressure and amount do not change. 

4Part(b) Step 2: Explanation

By using charles law , we get ;

We will convert the given temperature  in celcius , 

T2=680-273=407°C

V2=V1×T2T1=2500×40775=13566.6 mL

5Part(c) Step 1: Given information

We need to find that final volume, in milliliters, of the gas when the temperature changes to each of the following, if Pressure and amount do not change. 

6Part(c) Step 2: Explanation

By using charles law , we get ;

V2=V1×T2T1=2500×-2575     =- 832.5 mL

7Part(d) Step 1: Given information

We need to find that final volume, in milliliters, of the gas when the temperature changes to each of the following, if Pressure and amount do not change.

8Part(d) Step 2:Explanation

By using Charles law, we get ;

We will give temperature from Kelvin to Celcius 

T2=240-273=-33°C

V2=V1×T2T1=2500×-3375=- 1100 mL
