For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg −1 ⋅K −1. [3] Specific heat capacity often varies with temperature, and is different for each state of matter.
The SI unit for heat capacity of an object is joule per kelvin (J/K or J⋅K −1). Since an increment of temperature of one degree Celsius is the same as an increment of one kelvin, that is the same unit as J/°C. The heat capacity of an object is an amount of energy divided by a temperature change, which has the dimension L 2 ⋅M⋅T −2 ...
However, water has a very high volumetric heat capacity, at 4.18 MJ⋅K −1 ⋅m −3, and ammonia is also fairly high: 3.3 MJ⋅K −1 ⋅m −3. For gases at room temperature, the range of volumetric heat capacities per atom (not per molecule) only varies between different gases by a small factor less than two, because every ideal gas has ...

Data in the table above is given for water–steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. Pressure of the equilibrium is given in the second column in kPa. The third column is the heat content of each gram of the liquid phase relative to water at 0 °C.
Former Connecticut Gov. M. Jodi Rell, who took over the office to become the second female governor in state history after her predecessor resigned amid a corruption scandal, has died. She was 78.
The New York Rangers and the Carolina Hurricanes hold a moment of silence for Adam Johnson prior to their game at Madison Square Garden on November 2, 2023, in New York City.
