Steam undergoes a change from an initial state of 450 c and 3000 kpa to a final state of 140 c and 235 kpa. determine ah and as (a) from steam-table data (bby cquations for an ideal gas.

Nonmetals usually react by gaining electrons

The answer to this problem is. 67

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. 

Ci hope  it  you
