The measure of energy used in electrochemistry is the cell (Ecell), which is the difference in electrical potential between two electrodes. A common term for this difference in electrical potential is force or emf.

they begin to vibrate harder causing the material that was solid to turn into a liquid i.e gallium or ice

the answer would be a

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
