Answer
To calculate the force exerted by the gas on the piston, we can use the formula:
where:-
is the force in Newtons (N),-
is the pressure in pascals (Pa), and-
is the area in square meters (m²).First, we need to convert the pressure from atmospheres to pascals. The conversion factor is:
Given that the pressure of the compressed gas is
, we convert this to pascals:
Now, we can calculate the force:
Rounded to three significant figures, the force exerted by the gas on the piston is:
So the final answer is:
