A man ate 0.489 pound of cheese (an energy intake of 3.10 × 103 kJ). Suppose that none of the energy was stored in his body. What mass (in grams) of water would he need to perspire in order to maintain his original temperature? (It takes 44.0 kJ to vaporize 1 mole of water.) Enter your answer in scientific notation.

Mass of water required is 1268.18 g.

Explanation:

It is mentioned that the energy intake of 0.489 pounds of cheese is 3100 kJ.

And, 1 mole of water takes 44.0 kJ of energy. Hence, we will calculate the molar mass of water as follows.

    Molar mass of  is =

                               =

                               = 18 g/mol

This means that 18 g of water takes 44.0 kJ of energy

. Therefore, mass of water required for 3100 kJ of energy will be calculated as follows.

           Mass =

                     = 1268.18 g of water

Thus, we can conclude that mass of water required is 1268.18 g.

i need mutiple choices

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
