Question: Area of piston is 1 m<sup>2</sup>. When heat is supplied to the gas it expands and displaces piston ...

Area of piston is 1 m2. When heat is supplied to the gas it expands and displaces piston by L2\frac{L}{2} 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 = 2KxA\frac{2Kx}{A}

= 2×1001\frac{2 \times 100}{1} × 12\frac{1}{2}

= 100 N/m2
