0 1 Figure 1 shows an electric steam iron.
Figure 1
Water from a reservoir drips onto an electrically-heated metal plate. The water boils
and steam escapes through holes in the metal plate.
The electrical power of the heater inside the iron is 2.1 kW.
Assume that all the energy from the heater is transferred to the metal plate.
0 1
. 1 The metal plate has a mass of 1.2 kg and is initially at a temperature of 20 °C.
The heater is switched on. After a time t the metal plate reaches its working
temperature of 125 °C.
Calculate t.
specific heat capacity of the metal = 450 J kg−1 K−1

outside the
box
Water at 20 °C drips continuously onto the metal plate.
Steam at 100 °C emerges continuously from the iron.
The maker claims that the iron can generate steam at a rate of 60 g min−1.
Determine whether this claim is true.
specific latent heat of vaporisation of water = 2.3 106 J kg−1
specific heat capacity of water = 4200 J kg−1 K−1
