When the gas was compressed, its volume decreased from 8 to 5 liters, and the pressure increased to 1050 Pa. Find the initial pressure?
Data: V1 (initial gas volume) = 8 l; V2 (final volume) = 5 l; P2 (final pressure) = 1050 Pa; the process of compression of the taken gas will be considered isothermal.
To find the initial pressure of the taken gas, we use the proportion: P1 * V1 = P2 * V2 and P1 = P2 * V2 / V1.
Calculation: P1 = 1050 * 5/8 = 656.25 Pa.
Answer: The initial pressure was 656.25 Pa.
