Cilindrii din figura de mai jos sunt fixati conform desenului. Pistoanele avand ariile S1=100cm^2 respectiv 50cm^2, sunt uniti cu o tija rigida. In interiorul vaselor se gaseste aer la temperatura 27C si presiunea normala. Aerul din cilindrul mai mic este incalzit cu 50C. Cu cat trebuie modificata temperatura aerului din cilindrul celalalt pentru ca pistoanele sa ramana in aceeasi pozitie?
