During a physics laboratory experiment, a student uses an electric immersion heater to warm a solid block of aluminium.
The immersion heater has a power rating of 60 W.
The specific heat capacity of aluminium is 900 J/kg ∘C900 \text{ J/kg }^\circ\text{C}900 J/kg ∘C.
Show that it takes the heater about 680 s to raise the temperature of a 0.80 kg block of aluminium from 18∘C18^\circ\text{C}18∘C to 75∘C75^\circ\text{C}75∘C.
Use equations from the formula sheet.
