5. ANALYZING RESULTS A student has the fol-lowing data: V1= 822 mL, T1= 75°C, and T2=−25°C. He calculates V2 and gets −274 mL. Is this value correct? Explain why or why not.

The value is not correct because volume cannot be negative

Explanation:

Now let us perform the calculation together in order to know the correct value. We have values of pressure and temperature so we need to apply Charles law to the problem.

V1= 822mL

T1= 75°C +273= 348 K

T2= -25°C +273 = 248 K

V2= ???

From

V1/T1 = V2/T2

V1T2 = V2T1

V2= V1T2/T1

V2= 822× 248/348

V2= 585.8 mL this is the correct answer.
