Question

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 1

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
