Constant Pressure Process

For a mass of gas consisting of n= moles at a pressure

= kPa = x10^ Pa, = kPa = 10^x Pa, 中文译文中的待填/计算数值依次对应：1：p 2：pb 3：pp。实际数值以上方原输入框为准。

the expansion from

= m3

to 到 = m3

involves an amount of work

= J = x10^ J

In order to accomplish this work, energy must be added, and to calculate this energy, the temperatures must be determined. They can be calculated from the pressure and volumes using the ideal gas law:

= K

= K

Then if the molar specific heat is 然后如果摩尔定压热容是

= J/mole K = J/(mol·K) 中文译文中的待填/计算数值依次对应：1：cp。实际数值以上方原输入框为准。

the amount of heat required is given by

= J = x10^ J
