Gasoline has an enthalpy of combustion 24000 kJ/mol gallon. When gasoline burns in an automobile engine, approximately 30% of the energy released is used to produce mechanical work. The remainder is lost as heat transfer to the engine's cooling system. As a start on estimating how much heat transfer is required, calculate what mass of water could be heated from 25^(@)C to 75^(@)C by the combustion of 1.0 gallon of gasoline in an automobile? (Given : C(H_(2)O)=4.18 J//g^(@)C ) a) 34.45 kg b) 80.383 kg c) 22 kg d) 224 kg

Each question contains STATEMENT-1 (Assertion) and STATEMENT-2( Reason). Examine the statements carefully and mark the correct answer according to the instruction given below: STATEMENT-1: For the reaction at certainn temperature A(g)+B(g) iff C(g) there will be no effect by addition of inert gas at constant volume. STATEMENT-2: Molar concentration of all gases remains constant.

A heating coil is immersed in a 100 g sample of H_(2)O (l) at a 1 atm and 100^(@) C in a closed vessel. In this heating process , 60% of the liquid is converted to the gaseous form at constant pressure of 1 atm . The densities of liquid and gas under these conditions are 1000 kg//m^(3) and 0.60 kg//m^(3) respectively . Magnitude of the work done forthe process is : (Take : 1L-atm= 100J)
