An electric heater immersed in water of mass m, raised the temperature of the water from 40°C to 100°C in 5.00 minutes. After another 11.25 minutes, one-quarter of the water had been converted to steam. Calculate the specific latent heat of vaporisation of water. {Specific heat capacity of water = 4200 J kg-1 K-1}

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632
