5. According to Newton's Law of Cooling, the rate at which a substance cools in air is directly proportional to the difference between the temperature of the substance and that of air. If the temperature of the air is 30°C and the substance cools from 100°C to 70°C in 15 minutes, how long will it take to cool 100°C to 50°C?

Newton's Law of Cooling - Differential Equations The rate at which a body cools is proportional to the difference in temperature between the body and its surroundings. If a body in air at 0°C will cool from 200°C to 100°C in 40 minutes, how many more minutes will it take the body to cool from 100°C to 50°C?
Unreasonable Results - A slightly deranged Arctic inventor surrounded by ice thinks it would be much less mechanically complex to cool a car engine by melting ice on it than by having a water-cooled system with a radiator, water pump, antifreeze, and so on.

1. A room is filled with saturated steam at 100°C. Now a 5-kg bowling ball at 25°C is brought to the room. Heat is transferred to the ball from the steam, and the temperature of the ball rises to 100°C while some steam condenses on the ball as it loses heat (but it still remains at 100°C). The specific heat of the ball can be taken to be 1.8 kJ/kg · C. Solve for the mass of steam that condensed during this process. (3 DECIMAL IN FINAL ANSWER PLS)
Question # 2 A gas of mass (4)kg undergoes a quasi-static expansion which follows a relationship p = a+bv, where ‘a’ and b are constants. The initial and final pressures are (1017) kpa and (217) kpa respectively and corresponding volumes are 0.2meter cubic and 1.2meter cubic. The specific internal energy of the gas is given by u=1.5 pv -85kJ/kg, where ‘p’is in kpa and ‘v’is in m3/kg. Describe the process involved in given system and calculate the net heat transfer and the maximum internal energy of the gas during expansion. (m3 means metercubic).
