Question

moles of an ideal gas (r=1.4) was allowed to expand reversibly and adiabatically from
527°C to 32 L. The molar enthalpy change of the gas is
4200R
27-2100 R
3) -1500 R
4) -3000 R​

Answer 1

Moles of an ideal gas (r=1.4) was allowed to expand reversibly and adiabatically from

527°C to 32 L. The molar enthalpy change of the gas is (-2100 R)

•Mass of Water,

•Heat capacity of Water,

•Temperature rise,

•Energy transferred,

•Moles of Propane burned,

•Molar Enthalpy change,

•Molar Enthalpy change those things are too much important for molar enthalpy changes

when we will be abe to put the required amount of those ingredients

we will determine the molar enthalpy easily
