The sausages in The Hotdogger were not boiled in water, but heated by sending electricity through them. The sausages were connected in parallel and the machine could heat six sausages in 60 s. The machine converted energy with the power 1500 W and was connected to 120 V.
a) Calculate the current through each of the six sausages during heating.
b) Calculate how much electrical energy is deposited in a sausage during heating.
The specific heat capacity of a sausage is c = 3.45 kJ / kg * K, and a sausage has a mass of 60 grams.
c) Assess how much the temperature of the sausages increases with the 60 second heating.
Explain the relevant assumptions below.
