Whether the given statement is true or false.

Question

Thermodynamics: Mass and Energy Analysis Of Control Volumes Stainless steel ball bearings (ρ = 8085 kg/m3 and cp = 0.480 kJ/(kg◦C)) having a diameter of 1.5 cm areto be quenched in water at a rate of 900 per minute. The balls leave the oven at a uniform temperature of1000◦C and are exposed to air at 25◦C for a while before they are dropped into the water. If the temperatureof the balls drops to 900◦C prior to quenching, determine the rate of heat transfer from the balls to the air.
