Stoichiometry Pick out the wrong unit conversion of heat transfer rate. 1 BTU/ft².hr = 2.712 kcal/m².hr 1 Watt = 1.163 kcal/hr 1 kcal/m².hr = 0.3687 BTU/ft².hr = 1.163 Watt/m² 1 kcal/hr= 1.163 Watt 1 BTU/ft².hr = 2.712 kcal/m².hr 1 Watt = 1.163 kcal/hr 1 kcal/m².hr = 0.3687 BTU/ft².hr = 1.163 Watt/m² 1 kcal/hr= 1.163 Watt ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry For a given mass of a gas at constant temperature, if the volume 'V' becomes three times, then the pressure 'P' will become 9P² 3P 9P P/3 9P² 3P 9P P/3 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry No cooling occurs, when an ideal gas undergoes unrestrained expansion, because the molecules Do work equal to loss in kinetic energy Exert no attractive force on each other Are above the inversion temperature Collide without loss of energy Do work equal to loss in kinetic energy Exert no attractive force on each other Are above the inversion temperature Collide without loss of energy ANSWER DOWNLOAD EXAMIANS APP
