Which statement best describes the direction of heat flow by conduction between two samples of the same material is it heat flows from faster molecules to slow or molecules when they are near is it heat flows from faster molecules to slow or molecules when they collide is it heat flows from slower molecules to fast or molecules when they are near or heat flows from slow or molecules to fast or molecules when they collide

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.
