Question
"Thermodynamics" question.
Energy can be transferred into an isolated system by Mass transfer; Work transfer; Heat transfer; All of the above; None of above. For a closed system containing ideal gas, the boundary work can be calculated by W_b = mP_1(v_2 - v_1) for Isothermal (constant temperature) process defined by PV = Const.; Constant pressure process; Constant volume process; Polytropic process defined by PV^k = Const.; None of above. Please circle the substance(s) which has properties depends on temperature only Air; Carbon dioxide, CO_2; Superheated water vapor close to saturated vapor line; Saturated mixture of liquid water and vapor; Nitrogen, N_2 For an ideal gas, circle the parameter (s) which is (are) function of temperature only Specific volume, v; Specific internal energy, u; Specific heat at constant volume c_v; Pressure, P; Specific enthalpy, h; Circle the valid statement(s) associated with compressed liquid water. C_p is much larger than C_v c_p c_v; The effect of temperature on c_p is relatively small; The effect of pressure on c is relatively small; u u_f.Explanation / Answer
Answer:
1A: Answer is E. None of above
Because, An isolated system obeys the conservation law that its total energy–mass stays constant.
