Question

A cylinder measuring 9.7 cm wide and 12. cm high is filled with gas. The piston is pushed down with a steady force measured to be 18. N. piston cylinder Calculate the pressure of the gas inside the cylinder. Write your answer in units of kilopascals. Be sure your answer has the correct number of significant digits. kPa Check Explanation 5,174 30

Answer 1

Answer:

2.40 kPa

Explanation:

Given data:

radius or width of the cylinder d= 9.7 cm

radius r= 4.85 cm

height h= 12 cm

force applied from the piston F= 18 N

Area of the cross section of cylinder A=πr^2

$= \pi (0.0485)^2$= 0.007386 $m^2$

now, pressure P= Force / Area

$P= \frac{18}{0.007386}$

= 2437.04 $\frac{N}{m^2}$

= 2.437 kPa

correct to two significant figure = 2.40 kPa
