A gas at 65 degrees Celsius occupies 4.22L. At what Celsius temperature will the volume 3.87L, assuming the same pressure?
-kay so ive tried this one like a million times & i cant seem to get the right answer so pls talk me through the steps. like i know the equation is V1/T1=V2/T2 (volume & temp) & all it is is plugging in #s but im not getting the right answer !!! HELP. Like i even converted celsius to Kelvin and that's not workin. cos i have an answer sheet but doesnt shw us how.
If you had shown your work we could find your error. And you MUST convert temperature of 65 C to Kelvin (273+65 = 338 K), solve for the new T, then subtract 273 from the final T to arrive at final C. I suspect you may not be converting the final K temperature back to C.

so this is what igot
338k x 4.22L/3.87L=368-273
then i get 95 degress celsius.
& the book answer says 37 degres celsius. ): what am i doing wrong !
See your post further up the board. Your other post.
To solve this problem, you are correct in using the equation V1/T1 = V2/T2, where V1 and T1 represent the initial volume and temperature, and V2 and T2 represent the final volume and temperature. Here's a step-by-step guide to help you solve it:
Step 1: Identify the known values:
- Initial volume (V1) = 4.22 L
- Initial temperature (T1) = 65°C
Step 2: Convert the initial temperature from Celsius to Kelvin:
To convert Celsius (°C) to Kelvin (K), you need to add 273.15 to the Celsius value. In this case, T1 in Kelvin can be calculated as follows:
T1 (Kelvin) = 65°C + 273.15 = 338.15 K
Step 3: Identify the desired volume:
- Final volume (V2) = 3.87 L
Step 4: Rearrange the equation and substitute the known values:
Using the equation V1/T1 = V2/T2, we can rearrange it to solve for the final temperature (T2) as follows:
T2 = (V2 * T1) / V1
Substituting the known values gives us:
T2 = (3.87 L * 338.15 K) / 4.22 L
Step 5: Calculate the final temperature:
T2 = 309.99 K
Step 6: Convert the final temperature from Kelvin back to Celsius:
To convert Kelvin back to Celsius, subtract 273.15 from the Kelvin temperature. In this case, T2 in Celsius can be calculated as follows:
T2 (Celsius) = 309.99 K - 273.15 = 36.84°C
Therefore, the final temperature, assuming the same pressure, is approximately 36.84°C.
