31. Heat is supplied only during the constant volume processes 2 3 and heat is rejected only during the constant volume processes 4 1. 32. The heat capacity ratio or adiabatic index is the ratio of the heat capacity at constant pressure to heat capacity at constant volume . 33. Since the medium inside the steel box is kept at a constant volume , a standing wave has the ability to be produced. 34. The anemone stabilizes itself by shutting its mouth, which keeps the gastrovascular cavity at a constant volume , making it more rigid. 35. Mostly, heating a body at a constant volume increases the pressure it exerts on its constraining walls, and increases its temperature. 36. For systems at constant volume the Helmholtz free energy is minimum and for systems at constant pressure the Gibbs free energy is minimum. 37. According to ratio of specific heats at constant pressure and at constant volume ( } } ) and is the pressure of the gas. 38. The gores make up for the volume lost on the inside of the joint, and keep the suit at a nearly constant volume . 39. Using the definition of the heat capacity at constant volume for the first differential and the appropriate Maxwell relation for the second we have: 40. It is relevant that for a system at constant volume and mole numbers, the entropy is a monotonic function of the internal energy.
