Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

Measuring the temperature of very cold substances can be challenging. Here is one way of measuring the temperature of liquid nitrogen. A 50g flake of aluminum is submerged in liquid nitrogen and left immersed until it is in thermal equilibrium. The flake is then removed and placed in a well-insulated container with 500ml of water at 30°C. When water and flake attain thermal equilibrium, the temperature of the water is found to be 25°C. What was the temperature of the liquid nitrogen?
A mass of 10 g of oxygen fill a weighted piston-cylinder device at 20 kPa and 94.0°C. The device is now cooled until the temperature is 0°C.

The change of volume is m³.

One kilogram of water is contained in a piston-cylinder device at 100 celcius. The piston rests on lower stops such that the volume occupied by the water is 0.835 m3. The cylinder is fitted with an upper set of stops. When the piston rests against the upper stops, the volume enclosed by the piston-cylinder device is 0.841 m3. A pressure of 200 kPa is required to support the piston. Heat is added to the water until the water exists as a saturated vapor. What is the moisture of the saturated mixture when the piston hits the upper stop?
