Noun1.gas constant- (physics) the universal constant in the gas equation: pressure times volume = R times temperature; equal to 8.3143 joules per kelvin per mole universal gas constant,R natural philosophy,physics- the science of matter and energy and their interactions; "his favorite subject wa...
To find the molar specific heat for the entire process involving a monatomic ideal gas, we will analyze the two stages of heating: 1. Heating at constant volume until the pressure is doubled. 2. Heating at constant pressure until the volume is
Since the volume and temperature remain constant for each series of measurements, the ideal gas law can be written as ΔPV=ΔnRT. Since Δn is equal to Δw divided by the molecular weight of hydrogen, calculate each value of Δn for each value of Δw. Plot the product of pressure chan...
One mole of an ideal gas expands adiabatically from 200 K to 250 K. If the specific heat of the gas at constant volume is 0.8 kJ kg-1 K-1. then the work done by the gas is r6 oo 200K od 250 Ks'gog)63=0.8kJkgK )Options:20J120kJ40J40kJ A 相关知识点: 试题来源: 解析 ...
We can use the combined gas law, keeping volume constant (), thus it simplifies to: Rearranging to solve for : Conclusion: When the temperature is raised to 500 K, the pressure inside the container increases to 4.0 atm. Example 3: Determining Final Temperature after Compression A gas occupies...
4 Which statement about an ideal gas is correct?AA The density of an ideal gas at constant temperature is inversely proportional to the pressure.BOne mole of any ideal gas occupies the same volume under the same conditions of temperature and pressure.CThe volume of a given mass of an ideal...
