Question

A spring-loaded piston-cylinder device contains  of m=1 kg carbon dioxide. Initially, the spring has no force on the piston and , , . Heat is transferred to the gas, causing the piston to rise and to compress the spring. At the state 2,  , . The gas is an ideal gas.

(4)What's the boundary work against piston ?____in kJ?

 

A spring-loaded piston-cylinder device contains m = 1 kg of carbon dioxide. Initially, the spring has no force on the piston, and \( P_1 = 500 \text{kPa} \), \( T_1 = 150 \text{K} \), \( V_1 = 0.1 \text{m}^3 \). Heat is transferred to the gas, causing the piston to rise and compress the spring. At state 2, \( T_2 = 900 \text{K} \), \( V_2 = 0.3 \text{m}^3 \). The gas is an ideal gas. **Question:** (4) What is the boundary work against the piston \( W_{b-p} \) in kJ? **Diagrams Explanation:** There are two diagrams representing the states of the piston-cylinder system: 1. **State 1 (Initial State):** - Depicts a piston-cylinder with a spring at the top, showing the parameters \( P_1, V_1, T_1 \). 2. **State 2 (Final State):** - Depicts the piston-cylinder after the piston has risen and the spring is compressed, showing the parameters \( P_2, V_2, T_2 \).
