HG-1 THE HEAT OF FUSION OF ICE Introduction When heat flows into a system there are a number of things that can happen. One result could be a temperature rise. Or‚ the system might even catch fire. A third possibility is a change of state. As you know‚ matter exists in three states (or maybe four‚ the fourth being a plasma)‚ solid‚ liquid and gaseous. At different temperatures‚ the same substance may be in different states. Each state is characterized by the way the interatomic forces act. In solids

PHYSICS 1 MIDTERM EXAM REVIEW #2 1. A 6.0-N force and an 8.0-N force act concurrently on a point. As the angle between these forces increases from 0° to 90°‚ the magnitude of their resultant (1) decreases (2) increases (3) remains the same 2. A car increases its speed from 9.6 m/s to 11.2 m/s in 4.0 s. The average acceleration of the car during this 4.0-second interval is (1) 0.40 m/s2 (3) 2.8 m/s2 (2) 2.4 m/s2 (4) 5.2 m/s2 3.

AP Human Geography Chapter 1 review Because of the rise of the rest‚ the world has encountered its third shift of global power in the history of the Modern World. The rise of the Western World was given precisely at the moment of the Renaissance and the Enlightenment‚ when classic knowledge was rediscovered. The importance of the 3 rises is immensely important to the development of modern society. Besides the rise of the rest‚ Zachariah imposes his opinion on what should be done and what

AP Biology Lab 1 Ross Lordo Introduction Questions 1. The solute potential would be -2.48. If the concentration inside the cell is .15 M‚ then would diffusion out of the cell and into the solution of .1 M. This is due to water potential and the tendency for water to move from areas of high water potential to low water potential. 2. The turgor pressure must be equal to the water potential if there is no net diffusion. The cell and environment have reached equilibrium and the movement of water

A negative charge because when it is negatively charged electrons are added to the penny. 17. What is the voltage at the location of a 0.0001 C charge that has an electric potential energy of 0.5 J (both voltage and potential relative to the same reference point)? Potential = energy Charge = 0.5 J / 0.0001
