An object follows Newton's law of Heating/Cooling. If the object cools from 101°C to 81°C after 31minutes. Note: the ambient temperature is 24°C. How much more time(minutes) needs to pass to reach 44°C. Show your solution in step by step process.

3) An ideal gas is enclosed in a cylinder with a movable piston on top of it. The piston has a mass of 8 000 g and an area of 5.00 cm2 and is free to slide up and down, keeping the pressure of the gas constant. How much work is done on the gas as the temperature of 0.200 mol of the gas is raised from 20.0°C to 300°C?

A mass of gas at an initial pressure of 28 bar, and with an internal energy of 1500 kJ, is contained in a well-insulated cyclinder of volume 0.06m3. The gas is allowed to expand behind a piston until its internal energy is 1400 kJ; the law of expansion is pv2= constant. Calculate. (i) the work done (ii) the final volume (iii) the final pressure
