Answer:
The starting volume is 691 mL
Explanation:
The compete question is:
When the volume of a gas is changed from ___ mL to 852 mL, the temperature will change from 315 °C to 452 °C. What is the starting volume?
Write Charles Law and substitute values in:
V1 / T1 = V2 / T2
V1 / 588 K = 852 mL / 725 K
V1 (725 K) = (852 mL) (588 K)
V1 = 691 mL
Note the large °C values, trying to get you to forget to add 273. Remember, only Kelvin temperatures are allowed in the calculations.
