That means you need the specific heat of water and the molar mass of water. The molar mass of water is 18.0 g/mol. molarheatcapacity=(4.18Jmol∗K)(18.0g1mol) Multiplying that together you get: molarheatcapacity=75.2J/mol∗K
The molar heat capacity (C_p) of water at constant pressure is 75 J.K-1.mol-1. The increase in temperature (in K) of 100 g of water when 1 k.J. of heat is supplied to it is. ( ) A. 2.4 B. 0.24 C. 1.3 D. 0.13 相关知识点: 试题来源: 解析 A 反馈 收藏 ...
What is the heat capacity of 1.49 moles of liquid water? If the specific heat capacity of water in the liquid state is 1.0cal/g degrees Celcius, calculate the molar heat capacity of water in J/mol degrees Celcius. The specific heat of water is 4.18 \dfrac{J...
The temperature of a solid and liquid element rises when we supply heat to it. If we supplied the same amount of heat to two different kinds of solid then rise in temperature may be different in both the solids.This is the Specific heat Capacity.
For the calculation of the specific heat capacity at constant volume, cv some relationships are available. An exact thermodynamic derivation leads to the equation: (5.9)Cp−Cv=α2VT/κ where V is the molar volume (mol m−3), α is the expansion coefficient (K−1), and K is the ...
【题目】比热容问题The molar heats of fusion and vaporization for water are 6.02kJ/mol and 40.6kJ/mol, respectively, and the specific heat capacity of liquid water is 4.18J/gC. Given that the specific heat capacities of ice and steam are 2.06J/g℃ and 2.03J/g℃. Calculate the total ...
Heat capacity of a polystyrene sulfonate ion-exchanger has been investigated with a TIAN-CALVET microcalorimeter as a function of the water content. Three ionic forms K +, Na + and Ba 2+ were examined. The partial molar heat capacity of water has been then deduced. The observed variations ...
Molar Heat Capacity Examples Water has a molar specific heat capacity of 75.32 J/mol·K. Copper has a molar specific heat capacity of 24.78 J/mol·K. Molar Heat Capacity Versus Specific Heat Capacity While molar heat capacity reflects the heat capacity per mole, the related termspecific heat ...
