An electric shower takes in cold water at 17°C. The shower gives 6000 J of energy every second to the cold water and heats it to 37°C. The specific heat capacity of water is 4200 J/(kg "C).What is the mass of hot water supplied by the shower in one second?​

Answer»

Specific heat: = energy required to CHANGE a UNIT mass of a MATERIAL by 1°C. ... L = latent heat ... Lvaporization = 2.3 X 106 J kg-1. M = 1 kg. DE = energy to heat water to BOILING point
