Steady states If a function frepresents a system that varies intime, the existence of lim f12 means that the system reaches a steadystate (or equilibrium). For the following systems, determine whether asteady state exists and give the steady-state value.The amount of drug (in milligrams) in the blood after an IV tubeis inserted is given by m1t2 = 20011 - 2-2.

An ideal gas is confined to one side of a rigid, insulated container divided by a partition. The other side is initially evacuated. The following data are known for the initial state of gas: P1 = 5 bar, T1 = 500 K, and V1 =0.2 m3. When the partition is removed, the gas expands to fill the entire container, which has a total volume of 0.5 m3. Assuming that there is no change in the internal energy of the gas, determine the (a) pressure, in bar and the (b) product of mass, specific gas constant and T in the final state (in kPa-?3)
Entropy is one of the important coordinates in thermodynamics. Entropy shows the ratio of heat absorbed or rejected by temperature so that it can indicate the direction of heat flow. Entropy is useful for knowing the internal energy efficiency. Derive an equation for the change in the internal energy of a gas that satisfies the van der Waals equation of state.

for steam, the specific ideal gas constant = 461.5 J/kg K A closed system is comprised of pure water substance initially at a temperature of 500 oC and a pressure of 20 MPa (state 1). The system undergoes an isochoric process whereby its pressure drops to 0.1 Mpa (state 2). For state 1 evaluate the specific volume assuming the steam behaves as an ideal gas and comment on your result.

Pls ASAP thanks in advance Question 1 This question requires the use of the Thermodynamic Property Tables supplied as additional material. A closed system comprises a rigid (non-deformable) vessel of volume 0.3 m3 containing 5 kg of pure water substance, initially at a pressure of 30 bar (state 1). (a) For state 1, show that the system is in the two phase region The system now undergoes an isochoric (constant volume) process during which its pressure increases to 70 bar (state 2). (b) For state 2 show that the system is now in the superheated region. (c) Sketch the process described above on a pressure v specific volume diagram. Include in your sketch the boundaries between the liquid, two phase and vapour regions, and the critical pressure.
Thermodynamics A Piston-Cylinder system initially contains R-134a refrigerant at a temperature of 2.8 bar and 40 C, and its initial volume is 0.1 m3. First, heat is transferred to the system by keeping the piston constant and this process is continued until the pressure is 3.2 bar. the process is maintained by allowing the volume to change. At the end of this process, the temperature reaches 50C. Assuming the state changes as if balanced, calculate the following: a)He amount of heat transferred during constant pressure operation b)Show the state changes on the P-v diagram.

Krypton in a closed system is compressed adiabatically from 74 K and 1 bar to a final pressure of 24 bar. What is the final temperature in K? Assume krypton is an ideal gas. From Appendix B in the text, we can assume the heat capacity of krypton is independent of temperature and CP=2.5R , where R is the molar gas constant R=8.314 J/(mol K). For an ideal gas, recall CV=CP−R=1.5R. Report your answer in units of K using three decimal places.
