Homework Help: Termodinamics getting grade tommorow

  1. Nov 20, 2011 #1
    1. The problem statement, all variables and given/known data
    When the volume of a gas is reduced with fp% and the gas is heaten with ΔT K, the pressure of it grows with fp%.Find initial temperature Ti.
    Application: fv%= 20%; ΔT 12 K; fp% = 30%

    2.A aluminium calorimeter with the mass m1 contains the mass m2 of water heated at T1.In the water from calorimeter is inserted a body of lead(Pb) at mass m3 at the temperature of T3 (>T1).The termic equilibrum is set at the temperature T.We have the specific heats c1 and c2 of the aluminium and of the water.Find the specific heat c3 of the lead.
    Application: m1 = 41,6 g; m2 = 0,232 kg; T1= 288 K; m3 = 0,1 kg; T3 = 373 K; T =289K; c1 = 920 J/(kg * K); c2 = 4180 J/(kg * K).

    2. Relevant equations

    At 1 the T1 = 300k and at 2 c3 = 120 J(kg *K)

    3. The attempt at a solution
