Heat & Thermodynamics
The entropy change when 2 moles of an ideal monoatomic gas us subjective to change in state from (1atm,10L) to (2atm,5L) will be : (In2=0.7)
A cyclic process ABCA is shown in the volume-temperature diagram. Process on the pressure-volume diagram is:
In the given graph an ideal gas changes its state from A to state C by two paths ABC and AC. The internal energy of gas at A is 10J and the amount of heat supplied in path AC is 200J. The internal energy (inJ) of gas at C is 6k2. What is the value of k?
The table given below shows two different processes. Calculate the unknown values with help of first law of thermodynamics. All the data are in joule :
A vertical cylinder contains ideal gas with the help of two pistons whose combined mass is M.Pistons are connected by an inextensible string. The difference in the area of pistons is A. Atmospheric pressure is P0 Initially the system is in equilibrium as shown in the figure. Now heat is supplied to the system. Mark the correct statement (s).
The volume V versus temperature T graphs for a certain amount of a perfect gas at two pressures p1 and p2 are as shown in Fig. It follows from the graphs that p1 is greater than p2.
5 kilomoles of oxygen is heated at constant pressure. The temperature of the oxygen gas is increased from 295 K to 305 K. If the molar heat capacity of oxygen at constant pressure is 6.994 kcal/kmole K. The amount of heat absorbed in kcal,
