The drawing shows a hydraulic chamber with a spring (spring constant = 1600 n/m) attached to the input piston and a rock of mass 40.0 kg resting on the output plunger. the piston and plunger are nearly at the same height, and each has a negligible mass. by how much is the spring compressed from its unstrained position?

Explanation:

Given:

Now, the force due to the mass:

Compression in Spring:

or

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
