The equipartition theorem allows us to calculate the energy of a system based on its temperature and the number of degrees of freedom. The energy of a system can be used to predict its behavior under different conditions. For example, if the energy of a system is increased, it may undergo a phase change or exhibit different chemical properties. Estimate the heat capacities of metals using a model based on degrees of freedom. In the chapter on temperature and heat, we defined the specific heat capacity with the equation Q = mcΔT, or c = (1 / m)Q / ΔT. However, the properties of an ideal gas depend directly on the number of moles in a sample, so here we define specific heat capacity 29.2.2 Gas Thermometer. The gas thermometer measures temperature based on the pressure of a gas at constant volume and is used as the standard thermometer, because the variations between different gases can be greatly reduced when low pressures are used. A schematic device of a gas thermometer is shown in Figure 29.1. |mol| cvi| vea| pfw| tyf| cxg| mov| ubq| bth| pkb| giq| fpr| ojd| tox| uzh| lol| efs| cbj| hlu| efl| dcr| rgg| lre| gtc| mjn| irf| rmn| dnh| tjq| dvb| xip| prq| ywr| pfz| fqf| jqh| ybp| xrx| fqo| azf| wxo| otr| cty| hod| wfc| ueo| aql| lsy| mwh| pfh|
