A student is asked to determine the identity of an unknown metal. The student decides to use a calorimetry experiment to find the specific heat. The student will use this as a means of identifying the metal Initially, the temperature of the metal is 100°C and the water is 18.2°C. Which statement best describes the net flow of energy once the metal is placed in the water? A Energy flows from the water into the metal
B Energy flows from the metal into the water and the calorimeter
С Energy does not flow because the metal and water don't mix.
D Energy flows from the calorimeter into the water and metal​

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.
