Basic Thermodynamic Processes

The word 'thermodynamics' can be divided into two words, 'thermo' and 'dynamics'. The word thermo deals with the heat and thermal phenomenon, whereas dynamics deals with forces or external agent that drives the heat flow or aids in the motion of heat.

3.0 kg of steam at a pressure of 100 kPa are contained in a rigid sealed tank of volume 5.95 m3. The steam begins to cool as heat is transferred to the atmosphere. When the internal pressure reaches 10 kPa, the tank walls will collapse.a) What is the initial temperature of the steam in the tank (in oC)?b) What will the temperature be in the tank when the walls collapse (in oC)?c) Attheinstantofcollapse,whatisthemassofwaterinthevapourandliquidstate (in kg)?d) Deduce the work done for this process
A student living in a 4-m x 6-m x 6-m dormitory room turns on her 150-W fan before she leaves the room on a summer day, hoping that the room will be cooler when she comes back in the evening. Assuming all the doors and windows are tightly closed and disregarding any heat transfer through the walls and the windows, determine the temperature in the room when she comes back 10 h later. Use specific heat values at room temperature, and assume the room to be at 100 kPa and 15°C in the morning when she leaves.

Many gyms and health clubs have steam saunas, which are small steam-filled rooms. Traditionally, steam saunas have a container of heated rocks. A small ladle of water is poured on the rocks in order to make the steam. Use what you have learned so far about heat transfer to explain how hot rocks can be used to make steam? Why do you think only a small ladle-full of water is poured on the rocks at one time?
A Styrofoam coffee cup contains 125 g of hot coffee at 95.0 oC. A 25.0-g ice cube at -20.0 oC is dropped into the hot coffee. After the ice melts and thermal equilibrium is reached, the resulting liquid has a temperature of 65.0 oC. The specific heat capacity of ice is 1.99 J g-1 oC-1 and that of water is 4.184 J g-1 oC-1. The heat capacity of the coffee cup is 15.0 J oC-1. Calculate the molar heat of fusion for water. Assume the coffee is essentially pure water (FW 18.015) and that no heat enters or escapes from the system.
An ordinary egg can be approximated as a 5.5-cm-diameter sphere. The egg is initially at a uniform temperature of 8°C and is dropped into boiling water at 97°C. Taking the properties of the egg to be ρ = 1020 kg/m3 and cp = 3.32 kJ/kg·°C, determine how much heat is transferred to the egg by the time the average temperature of the egg rises to 70°C.

A polyatomic gas operating in excess of 2000K through an adiabatic process would require a smaller compression ratio than the same polyatomic gas operating at under 2000K to produce the same amount of work. Explain why.
The initial state of 1.00 mol of a dilute gas is P1 = 3.00 atm, V1 = 1.00 L, and Eint1 = 456 J and its final state is ?2 = 2.00 atm, V2 = 3.00 L, and Eint 2 = 912 J. The gas is heated and is allowed to expand such that it follows a single straight-line path on a PV diagram from its initial state to its final state. (a) Illustrate this process on a PV diagram and calculate the work done by the gas. (b) Find the heat absorbed by the gas during this process.
