1.2 Joule

solution,

Force=4 N

Distance=0.3 m

Now,

hope this helps...

Good luck on your assignment....

Spontaneity tell us the direction of the reaction, but not how fast it goes. gibbs free energy brings together enthalpy, entropy and temperature in one easy formula. g = h - ts. and, finally the sign of delta g is always negative for a spontaneous reaction.

The answer should be vaporization
