The advantage of a hydraulic lift is that a force applied to a small piston allows you to lift an object with a weight much greater than the applied force. However, the smaller piston must be pushed down a farther distance than the larger piston is raised. Use the concept of Pascal’s principle to explain why this is.

small = small current large mag large current

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
