In a closed rigid vessel that does not have any type of work
interactions with the surroundings the amount of heat that needs
supplied to heat a liquid inside the container can be determined by
the change in internal energy. Suppose you have a sealed pan with 1
liter of water at 20 °C and 100 kPa that you want to heat to 70 °C.
Do the following:
a. Represent the process on a T-v diagram. Indicate T (°C) and v
(m3/kg) values and draw the corresponding isobars.
b. Determine the amount of heat that needs to be supplied such that
the resulting temperature is 70 °C.
Hint: for pure substances in a compressed liquid state the value of
thermodynamic properties, in absence of compressed liquid tables,
can be approximated as equal to the saturated liquid value of the
property at the temperature of the substance.
Please show as much detail as possible, Thank you very much in advance!

An insulated rigid vessel contains 5kg of saturated liquid-vapor mixture of Refrigerant- 134a at 200kPa. At this stage, one-fifth of the mass is in vapor phase and rest is in liquid. Now using an electrical resistance heater, heat is supplied to the contents of the vessel until all of the refrigerant is converted to saturated vapor. Show this process on a P v diagram with respect to saturation lines and determine, 1. volume of the rigid vessel 2. temperature, in...
1. The same reaction takes place in two different vessels, which are initially at atmospheric pressure (1 atm). The first vessel is rigid and does not expand with change in pressure; the second vessel will expand to maintain a pressure of 1 atm inside. Over the course of a reaction, the second vessel expands by 1 liter. a) What is the amount of PV work done by the reaction for each of the vessels?b) Which vessel’s content has a higher enthalpy?c) ...
1. What is the purpose of a constant volume gas thermometer. How does it work? 2. What is the difference, if any, between a isothermal and adiabatic thermodynamic process. Draw them on a pV diagram. 3. Does the First Law of Thermodynamics apply to solids and liquids? Why or why not. 4. What is the most important heat transfer mechanism on earth where there is an atmosphere? Explain how this can cool a nuclear or coal fired power plant, and...
5. A rigid tank initially contains 10 kg O2 at 200 kPa and 600
