Specific heat of ethanol
WebA $\pu{25.95 g}$ sample of methanol at $\pu{35.6 ^\circ C}$ is added to a $\pu{38.65 g}$ sample of ethanol at $\pu{24.7 ^\circ C}$ in a constant pressure calorimeter. If the final temperature of the combined liquids is $\pu{28.5 ^\circ C}$ and heat capacity of the calorimeter is $\pu{19.3 J/^\circ C}$ determine the WebIts heat capacity is approximately 24.5 joules per gram-degree Celsius (J/g°C), which is slightly higher than that of water (4.18 J/g°C). This means that it takes more heat to raise the temperature of ethanol by a given amount than it does to raise the temperature of water by the same amount. The heat capacity of ethanol is also dependent on ...
Specific heat of ethanol

WebThe heat capacity of the entire calorimeter system is thus C = Ccal + CEtOH The heat capacity of the ethanol ( CEtOH) depends upon how much ethanol is in the system. It is therefore more convenient to replace CEtOH with the specific heat capacity of ethanol ( sEtOH) and the mass of ethanol ( mEtOH ). C = Ccal + sEtOH mEtOH WebThe heat of vaporization for ethanol is, based on what I looked up, is 841 joules per gram or if we wanna write them as calories, 201 calories per gram which means it would require, …
