specific heat, the quantity ofheatrequired to raise thetemperatureof onegramof a substance by oneCelsiusdegree. The units of specific heat are usuallycaloriesorjoulesper gram per Celsius degree. For example, the specific heat ofwateris 1 calorie (or 4.186 joules) per gram per Celsius degree. ...
It is expressed in Joules per Kelvin.Specific Heat of Water When one boils water in a metal vessel, one notices that while the metal vessel is too hot to touch within seconds, the same is not true for the water. Instead, the water might be lukewarm or even colder in the initial 30 ...
Curves of specific heat plotted against temperature are presented for a synthetic zeolite (Linde 5A) at a number of water contents. Above a threshold water content of 0·233 g of water per gram of zeolite the curves showed a peak, centred about 30°C, that is ascribed to the fusion of ...
Specific Heat Capacity of Water at normal temperature and pressure is roughly4.2 J/goC. This means that 1 gram of water requires 4.2 joules of energy to raise 1 degree Celsius. Water has a high specific heat capacity. The actual value of water’s specific heat capacity is4182 J/kg °C. ...
specific heat 1.The ratio of the amount of heat needed to raise the temperature of a certain amount of a substance by one degree to the amount of heat needed to raise the temperature of the same amount of a reference substance, usually water, by one degree. Because molecules of different...
The heat capacity and temperature are proportional to each other. On increasing the heat capacity of water, its temperature also increases. The...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer y...
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...
specific heat specific heat, ratio of the heat capacity of a substance to the heat capacity of a reference substance, usually water. Heat capacity is the amount of heat needed to change the temperature of a unit mass 1°. The heat capacity of water is 1 calorie per gram per degree Celsiu...
【题目】The specific heat capacity of substance K, incalories per gram (cal/g), is approrimately 30%less than that of methyl alcohol. T he specificheat capacity of methyl alcohol is 0.60 cal/g.Which of the following is close to the specificheat capacity, in callg, of substance K (A....
be added to an object to raise its temperature by one degree is known as the heat capacity (H cap ) of that object. The thermal energy required to change the temperature of an object by several degrees is given in Equation 6.1. If thermal energy is measured in calories and temperature ...
