Area of piston is 1 m2. When heat is supplied to the gas it expands and displaces piston by 2L where L = 1m. Natural length of springs is L = 1m. Spring constant K = 100 N/m. The pressure of gas in final situation is –
A
50 N/m2
B
100 N/m2
C
200 N/m2
D
400 N/m2
Answer
100 N/m2
Explanation
Solution
P = A2Kx
= 12×100 × 21
= 100 N/m2
