Answer:
In summary, work is done when a force acts upon an object to cause a displacement. Three quantities must be known in order to calculate the amount of work. Those three quantities are force, displacement and the angle between the force and the displacement.

Answer:
true
Explanation
Unbalanced forces can cause an object to change its motion.If an object is at rest and an unbalanced force pushes or pulls the object it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion.
All I can say is that Mercury is a liquid at room temperature, and liquids will very slowly evaporate at room temperature. This is because the molecules have a relatively low energy at room temperature (since room temperature is very low compared to boiling point). The boiling point of mercury is 356.73 degrees Celsius, and room temperature is only about 23 degrees Celsius, so the evaporation rate at room temperature would be little to nothing.
