Can’t figure this one out. Help is appreciated.
P=E/t so t=E/P
change in temperature = 368K - 298K = 70K
t = (1 * 4200 * 70)/700 = 420 seconds
420/60 = 7 min
can you tell me why we took the mass in kg and then the specific heat capacity in grams? thanks
the units are balanced, the specific heat capacity was given in kg so i kept the mass in kg as well
4,2 kJ/kg/K = 4200 J/kg/K i converted kJ to J
