Water has a very high specific heat capacity of 4184 J/(kg·K) at 20 °C (4182 J/(kg·K) at 25 °C) —the second-highest among all the heteroatomic species (after ammonia), as well as a high heat of vaporization (40.65 kJ/mol or 2268 kJ/kg at the normal boiling point), both of which are a result of the extensive hydrogen bonding between its ...
The specific heat capacity of a substance, usually denoted by or , is the heat capacity of a sample of the substance, divided by the mass of the sample: [10] = =, where represents the amount of heat needed to uniformly raise the temperature of the sample by a small increment .
V – specific volume in cubic decimeters per kilogram (1 dm 3 is equivalent to 1 liter) H – specific enthalpy in kilojoules per kilogram; U – specific internal energy in kilojoules per kilogram; S – specific entropy in kilojoules per kilogram-kelvin; c p – specific heat capacity at constant pressure in kilojoules per kilogram-kelvin
C p is therefore the slope of a plot of temperature vs. isobaric heat content (or the derivative of a temperature/heat content equation). The SI units for heat capacity are J/(mol·K). Molar heat content of four substances in their designated states above 298.15 K and at 1 atm pressure. CaO(c) and Rh(c) are in their normal standard state of ...
Specific heat capacity of water [97] Self-ionization. Water is a weak solution of hydronium hydroxide—there is an equilibrium 2H 2 O ⇌ H 3 O + + OH −, in ...
ĉ V is the dimensionless specific heat capacity at constant volume, approximately 3 / 2 for a monatomic gas, 5 / 2 for diatomic gas, and 3 for non-linear molecules if we treat translations and rotations classically and ignore quantum vibrational contribution and electronic excitation.
