A 1.4 kg lump of alloy at
131\deg Cis added to 3.4 kg of water at
15\deg C.Melbourne is famous for its early morning hot-air balloon flights. One morning, the mass of the passengers, basket, and balloon material was 604 kg . Calculate the balloon's volume if the heated air inside the balloon has a density
14%less than that of the surrounding atmosphere. Hint: take the density of air to be
1.2kgm^(-3)Please report the volume in cubic meters to 0 decimal places. Calculate the equilibrium temperature if no heat is lost to or gained from the environment. Hint: the specific heat of water is
4186Jkg^(-1)K^(-1)and the specific heat of the alloy is 1,009
Jkg^(-1)K^(-1). Please report the temperature in degrees Celsius to 0 decimal places. Calorimetry (i.e. energy conservation with heat)
