Receiving heat

How many degrees Celsius was an iron cylinder weighing 300 g heated in a water bath if it received heat of 7.2 kJ? (specific heat capacity of iron c = 0.46kJ/kg / ºC)

Correct answer:

t =  52.1739 °C

Step-by-step explanation:

m=300 g kg=300/1000  kg=0.3 kg Q=7.2 kJ c=0.46 kJ/kg/°C  Q=mct  t=Qm c=7.20.3 0.46=120023°C=52.1739°C
