The specific heat at constant volume of liquid krypton has been measured within the temperature range from 116 to 200 K along the boiling line and at pressures up to 100 atm (10 MN m 2). In addition, the thermal pressure coefficient and the molar volume along the boiling line have been ...
Like other molecules, water has a distinct specific heat capacity that describes the heat needed to raise the temperature by 1 unit for one gram of water. From the specific heat capacity of water, we can determine the molar heat capacity using the molar mass of ...

The graph shows that for different values of pressure, CV tends to grow exponentially at low temperatures, whereas at high temperatures it attains a constant value. Every solid exhibiting the Dulong-petit law is defined by high-temperature variation57. Figure 12 Variation of specific heat (Cv) ...

So we'd say at constant pressure. So again, we're at that constant pressure in the cal perimeter. So to get to delta H of the reaction, we can just use our Q value here. However, think about what's happening here. This heat is the result of the ...
