No, momentum is conserved so:
momentum before=momentum after
it is C. 100 kg m/s
It is true that a physical change occurs when a material changes shape or size, but the composition of the material does not change. The correct answer is True.

Answer:
100 cc
Explanation:
Heat released in cooling human body by t degree
= mass of the body x specific heat of the body x t
Substituting the data given
Heat released by the body
= 70 x 3480 x 1
= 243600 J
Mass of water to be evaporated
= 243600 / latent heat of vaporization of water
= 243600 / 2420000
= .1 kg
= 100 g
volume of water
= mass / density
= 100 / 1
100 cc
1 / 10 litres.
