Give a scientific explanation for the following observations: Perspiring is a mechanism for cooling the body -is it because when something is heated it produces a salt and h2o, so when our body heats up the chemicals in our body
Give a scientific explanation for the following observations. Use equations or diagrams if they are relevant. A. burning coal containing a significant amount of sulfur leads to "acid rain". B. Perspiring is a mechanism for cooling
When a body hanging form a spring balance is immersed in water it floats just below the surface of water and shows 100 g loss in its water ? (1) what is the weight of the body in water? (2) what is the weight of the body in air?

Which provides more cooling for a styrofoam cooler, one with 10 lbs of ice at 0 degrees C or one with 10 lbs of ice water at 0 degrees C. Explain. qice=mass*heat of fusion. qH2O=mass*specific heat x delta T However, you aren't
At high concentrations of [H2] the observed rate law is found to change to the form: Rate = k[NO]^2 i.e. the rate becomes independent of [H2]. 1. Assess whether the two step mechanism: H2 + 2NO → N2 + H2O + O (k1) O + H2 → H2O
Which of the following is not an example of homeostasis? A) perspiring in order to restore normal body temperature B) feeling hungry and eating to restore the level of blood glucose to normal C) feeling hungry at the sight of
The toco toucan, the largest member of the toucan family, possesses the largest beak relative to body size of all birds. This exaggerated feature has received various interpretations, such as being a refined adaptation for
