What is the relation between the specific heat of gas at constant pressure (C) and the specific heat of gis at constant volume (C) at the absolute e point? aG=G G³G &G₂«G &G₂ G₂R . Nome 1 V. A machine which produces mechanical work without coumption of some energy is called as If value of a is. sa polytropic process, then the process is known as Hochoric VB. ich the saturated liquid and saturated vapor states are identical vill. A balloon containing an ideal gas is initially kept in an evacuated and insulated room The balloon ruptures and the pas fills sp the entire room. Which one of the following statement is true at the end of the above process? 1 The Internal energy of the ges decreases from its initial value, but the enthalpy remain contant The internal energy of the es coses from its initial value, but the enthalpy remains comptant Both internal energy and enthalpy of the gas mains constant Both internal energy and the enthalpy of the increase Final Exam M 201 Sem 422. JUC Male B Peg-2 of 28 ix. A cylinder contains 5 m² of an ideal gan at a pressure of 1 bor. This gn is compressed in a reversible isothermal process las pressure incesto 5 bar. The work in k required for this process is x. A small steam whistle (perfectly insulated and doing no shaft work) causes a drop of 0.2 kJ/kg in enthalpy of steam from entry to exit. The kinetic energy of the steam at entry is negligible, the velocity of steam at exitis (a)0.63 m/s (b) 0.44 ms 3 14.14 ms 620 m² il.
-1 The condition of perfect vacuum can be attained at a temperature of No liquid can exist as a liquidat pressure. Mixture of water and ice form a system. What is the relation between the specific heat of gas at constant pressure (C.) and the specific heat of gas at constant volume (Cp) at the absolute zero point? | 1 a. Cp-C b. Cp>C, C.C₂ <C, d. C₁-C-R e. None A machine which produces mechanical work without consumption of some energy is called as If value of n is. in a polytropic process, then the process is known as Isochoric. is that at which the saturated liquid and saturated vapor states are identical. A balloon containing an ideal gas is initially kept in an evacuated and insulated room. The balloon ruptures and the gas fills up the entire room. Which one of the following statement is true at the end of the above process? I 1 (a) The internal energy of the gas decreases from its initial value, but the enthalpy remains constant (b) The internal energy of the gas increases from its initial value, but the enthalpy remains constant (c) Both internal energy and enthalpy of the gas remains constant (d) Both internal energy and the enthalpy of the gas increase , ME 203, Sem 422.
