Boiling refers to which phase change? a. gas to solid b. liquid to gas c. solid to liquid d. liquid to solid user: what is the opposite of malleable? a. brittle b. ductile c. insulative d. conductive user: substances whose atoms readily give up electrons are considered to be which of the following? a. highly ductile b. good insulators c. highly malleable d. good conductors

Boiling refers to a change of state from a liquid to a gas, the opposite of malleable is brittle, I'm not sure about the last one but I think its B)

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. 

Ibelieve it's celsius. hope this .
