QuestionThermodynamics / entropy change on heating
When 100 g of water is reversibly heated from 27°C to 127°C at 1 bar, the change in entropy (ΔS) for the process is about : (Given : the specific heat capacity C_p of water is nearly constant at 4.2 J g⁻¹ °C⁻¹ in the temperature range 27°C to 127°C at 1 bar; ln 4 = 1.39; ln 3 = 1.10)
- (a) 29.4 JK⁻¹
- (b) 122 JK⁻¹
- (c) 7.0 JK⁻¹
- (d) 96.6 JK⁻¹
