According to the law of entropy, when hot and cold objects meet, heat flows from hotter to colder What would be the ondosolo mixing hot water and cold water
A)
The cold water would continue to heat up
The warm water would continue to cool down
The molecules in the cold water would stow down
D)
All the water would reach an equilibrium temperature and heat would stop
flowing

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
