g what mass of water must evaporate from the skin of a 70.0 kg man to cool his body 1.00 C? The heat of vaporization of water at body temp

The correct answer will be "100.7 mL". The further explanation is given below.

Explanation:

The given values are:

Temperature,

ΔT = 1°C

Mass,

m = 70 kg

c = 3.480 J/Kg.K

Amount of released heat will be:

⇒  

On putting the estimated values, we get

Let M will be the amount of evaporated water at the temperature of 37°C.

Required heat will be:

⇒  

Now, Lost heat will be equal to the required amount of heat.

⇒                          

On applying cross-multiplication, we get

Now,

⇒  

On putting the estimated values, we get

it is important to conserve water because there is very limited amount of freshwater here on earth and if we are not smart about how we use it we will only be runnning out of our supply faster than neccessarry.

the mantle

explanation:

earth is divided into three layers: the crust or the outermost layer on which we live; the underlying, middle layer - the mantle - and the core (the innermost layer of earth).
