Your question doesn't look right, so lemme assume you meant this.
A heater marked 60w evaporate 6x 10^-³kg of boiling water in 60 seconds. What is the specific latent heat of vaporization of water in jkg?
so you can understand it better..
Latent heat of evaporation is the heat required required to change water to vapor at the same temperature.(100°C)
eg. water boils at 100°C and in presence of more heat it turns to vapor at that Same temperature.
This heat is know as latent heat of Vaporization.
it's give by H=mL
where L is the specific latent heat of vaporization.
Explanation:
I think the answer is 18 km/h
Answer:
Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection. ... Therefore, our eye and brain track the light rays backward to a position from which they appear to have come.
