A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?

175 cm³ instead of 175 cm.

297.5 cm³

Explanation:

From the question;

Initial volume; V1 = 175 cm³

Initial temperature; T1 = 25°C

Final temperature; T2 = 42.5°C

From Charles law we can find the volume V2 from the equation;

V1/T1 = V2/T2

Making V2 the subject gives;

V2 = V1 × T2/T1

V2 = (175 × 42.5)/25

V2 = 297.5 cm³

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
