physics During exercise, a person may give off 753,480 J of heat in 30 minutes by evaporation of water from the skin. How much water has been lost?

Respuesta :

Answer : The amount of water lost was, 333.4 grams.

Explanation : Given,

Heat released = 753480 J

Formula used :

[tex]Q=mL[/tex]

where,

Q = heat released  = 753480 J

m = mass  = ?

L = latent heat vaporization of water = [tex]2260J/g[/tex]

Now put all the given values in the above formula, we get:

[tex]753480J=m\times (2260J/g)[/tex]

[tex]m=333.4g[/tex]

Thus, the amount of water lost was, 333.4 grams.
