Aperson eats a container of strawberry yogurt. the nutritional facts label states that it contains 255 calories (1 calorie = 4186 j). what mass of perspiration would one have to lose to get rid of this energy? at body temperature, the latent heat of vaporization of water is 2.42 106 j/kg.

mass = 0.44 Kg

Explanation:

given,                                                            

Calories contain in the strawberry yogurt = 255 calories

1 Calorie = 4186 J                                      

latent heat of vaporization = 2.42 x 10⁶ J/Kg

mass of perspiration = ?                      

Energy = 255 calories                      

Energy = 255 x 4186                            

            = 1067430 J                                    

Energy = mass x latent heat of vaporization

mass = 0.44 Kg                                                  

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat
