Web7 de sept. de 2012 · 12.5 k J of heat was absorbed by the surroundings. I found this by using the mcat formula and the specific heat capacity of water (4.18 J/ (g °C)): Q = m ⋅ c ⋅ Δ T Q = 950 g × ( 4.18 J ⋅ g − 1 ⋅ ∘ C − 1) × ( 23.25 ∘ C − 20.10 ∘ C) = 12508.7 J WebIt was originally defined so that the specific heat capacity of liquid water would be 1 cal/°C⋅g. The "grand calorie" (also "kilocalorie", "kilogram-calorie", or "food calorie"; "kcal" or "Cal") is 1000 small calories, that is, 4184 J, exactly. It was defined so that the specific heat capacity of water would be 1 Cal/°C⋅kg.

Web13 de feb. de 2024 · Water has a specific heat capacity of 4182 J/kg°C. Because water is such an important and common substance, we even have a special way to identify the amount of energy it takes to raise one gram of water by one degree Celsius—a Calorie. This is different from the kind of calorie we talk about in food.
