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 ...
WebHere, we focus on the heat capacity with the volume held constant. We can calculate it for an ideal gas. Heat Capacity of an Ideal Monatomic Gas at Constant Volume. We define the molar heat capacity at constant volume [latex]C_V[/latex] as [latex]C_V = \frac{1}{n}\frac{Q}{\Delta T},\text{with V held constant.}[/latex] This is often expressed in ...
