Colligative Properties The Physical Properties of Solutions Colligative Properties • There are 3 colligative or physical properties of solutions that you should know. They are Vapor pressure Boiling point elevation Freezing point depression Osmotic pressure is one you don’t need to worry about. 1. 2. 3. 4. Molality • Molality measures the moles of solute dissolved in the mass (kg) of solvent. • Molality normally expresses concentrations of colloids. • m = moles solute kg solvent

What Einstein Told His Barber Summaries Chapter 3 Summary Heat if a form of energy that all other forms of energy primarily evolve around. Whenever one form of energy transforms from one to another some of this energy is lost or gained in the form of heat. Restoring lost heat molecules and atoms needs energy so in the end you lose instead of gaining energy. Heat travels from areas of high temperature to areas of lower temperatures. Confusion of temperature and heat is a common. Heat is energy

Thinking back in time I found the poem “ This Moment” by Eavan Boland a complicated poem when I read it for the first time. I started to question myself once I finish reading it‚ what does this poem wants to tell us? The sentence was very short and each stanza doesn’t seem to be very related to each other. However‚ once I read it for the 2nd and 3rd time‚ I came to realize that the speaker wants to describe about a specific moment in her life. Starting from the daily life and activities she did

HW 1 solutions Point Charge in One Dimension A point charge q1 = -3.5 μC is located at the origin of a co-ordinate system. Another point charge q2 = 5.1 μC is located along the x-axis at a distance x2 = 9.3 cm from q1. 1) What is F12‚x‚ the value of the x-component of the force that q1 exerts on q2? -18.57 N For all of these problems we want to make use of the standard electric force equation: ̂ So for this problem with K=9*109 Nm2/C2‚ Q1=-3.5μC‚ Q2=5.1 μC‚ and r=9.3 cm we get F=-18.57

The Atom The basic idea of the atom was adopted by scientists thousands of years later because it explained new discoveries in the field of chemistry. Long after chemical atoms were found to be divisible‚ and even after smaller‚ truly indivisible particles were identified. Over time theories of the atom changed. The nature of atoms in philosophy varied a lot over time and between cultures and schools. The Plum Pudding Model was proposed in 1904 before the discovery of the atomic nucleus in order

Cebu Institute of Technology Phys 202 /K3 I. Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance

Mie resonances in dielectric particles can increase the local optical density of states (LDOS) associated with either electric or magnetic transition rates in nearby quantum emitters without ohmic losses. Their rather large quality factors compensate their low field confinement as compared to the plasmon resonances of metallic nanostructures for which nonradiative decay channels dominate. We show theoretically that near-infrared quadrupolar magnetic resonances in silicon particles can preferentially
