Specific heat capacity is the heat required to raise the temperature of 1g of an object by 1*C, and since this is divided by the amount of substance present, it is an intensive property. You can determine which one to use based on what you are given in the question (ex: moles, grams, etc.)
Heat capacity cannot be a negative value as it is a measure of how much energy is needed to raise the temperature of 1g or 1mol of a substance by one degree celsius and if you are raising the temperature you are inputting heat into the system so heat capacity would be positive. Top. Melissa Solis 1H.
Specific heat capacity is an intensive property because it is not dependent on the amount of the substance available. Specific heat is the amount of energy it takes to raise 1g of a substance by 1 degree C, so no matter how much of the substance you have, you can still calculate how much energy it would need to absorb to reach a specific ...
Re: Specific Heat Sig Figs. Postby Jonathan Shih 3H » Wed Jan 27, 2016 11:24 am. I think that although it is a pre-determined valued, these given values have probably been tested and calculated the many more sig figs, however, what we are given are usually the values rounded to a certain number of sig figs. Therefore, I do think that we have ...
Specific heat capacity is the heat capacity of the molecule divided by the mass (in grams) of the molecule. Molar heat capacity is the heat capacity of the object divided by the moles of the molecule. A question can ask for either one of these or both. In Lavelle's example, we calculated the heat capacity of some ethanol to be 49 kJ/C.
Postby Allison Maryoung 1D » Fri Jan 15, 2016 12:22 am. The specific heat capacity is the heat needed to raise the temperature of 1g of substance by 1 degree Celsius. 1 degree Celsius=1 degree Kelvin. When solving specific heat capacity in Kelvin, Kelvin=Celsius because the distance from one degree to the next degree in both Celsius and Kelvin ...
In thermodynamics, the heat capacity of a system is an intensive property that is the ratio of the heat added to the system to the resulting temperature change. The reciprocal of the heat capacity is called the specific heat, which is the amount of heat required to raise the temperature of one kilogram of the substance by one kelvin. The symbol ...
Heat capacity is an extensive property because it depends on the amount of the substance. Meanwhile, specific heat capacity is an intensive property because it does not matter the amount of substance present. For example in lecture, the heat capacity was 49 kj/c while the specific heat capacity is j/k × mol.
Specific heat capacity water vapor = 2.01 J.°C-1.g Molar heat capacity water liquid = 75.29 J·K-1 ...
The specific heat of octane, C8H18, is 2.22 J/g·K. (a) How many J of heat are needed to raise the temperature of 80.0 g of octane from 10.0 to 25.0 °C? (b) Which will require more heat, increasing the temperature of 1 mol of C8H18 by a certain amount or increasing the temperature of 1 mol of H2O by the same amount?
