1. Ignore o sistema termodinâmico e calcule o trabalho para elevar a massa M do ponto B para o C. Faça essa conta para cada caso analisado. O trabalho para esse sistema está ligado a energia potencial gasta para levar a massa de um ponto ao outro. W = E potencial = mg ∆h Onde m é a massa colocada no êmbolo em quilogramas, g a gravidade usada como 9,81m/s² e ∆h a diferença de altura do ponto B ao ponto C. W = 0,5 ( Kg ) × 9,81 ( m s 2 ) × 0,0266 ( m ) W = 0,0130 ± 0,0004 J W = 0,1 ( Kg ) × 9,81 ( m s 2 ) × 0,0258 ( m ) W = 0,0253 ± 0,0007 J W = 0,15 ( Kg ) × 9,81 ( m s 2 ) × 0,0267 ( m ) W = 0,039 ± 0,001 J W = 0,2 ( Kg ) × 9,81 ( m s 2 ) × 0,0258 ( m ) W = 0,051 ± 0,001 J W = 0,25 ( Kg ) × 9,81 ( m s 2 ) × 0,0237 ( m ) W = 0,058 ± 0,001 J Massa (Kg) W (J) Erro W 0,05 0,0130 0,0004 0,10 0,0253 0,0007 0,15 0,039 0,001 0,20 0,051 0,001 0,25 0,058 0,001

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
