It is the very first thing you do.

Figure 4: Four-Stroke Cycle In the first stroke, also known as the Intake Stroke or Induction, the piston travels from the top dead centre (TDC) to the bottom dead centre (BDC) with the intake valve open and exhaust valve closed.

A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?
patriot [66]

175 cm³ instead of 175 cm.

Answer:

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
