Specific Heat and Heat Capacity

2010-06-23T17:50:00.000-07:00

specific heat is one of the necessary material constants in physics, basic principles, formulas and applications relating to the use of specific heat in much more detail later learned, this article gives a brief description, along with examples of solid matter of the specific heat.Specific heat is another physical property of matter. All matter has a temperature associated with it. The temperature of matter is a direct measure of the motion of the molecules: The greater the motion the higher the temperature:

Concept
The amount of heat energy (q) gained or lost by a substance is equal to the mass of the substance (m) multiplied by its specific heat capacity (Cg) multiplied by the change in temperature (final temperature - initial temperature)

Specific Heat Capacity (C_g) of a substance is the amount of heat required to raise the temperature of 1g of the substance by 1^oC (or by 1 K)

Example
1. How much energy does it take to raise the temperature of 50 g of copper by 10^oC?

2. Calculate the amount of heat needed to increase the temperature of 250g of water from 20^oC to 56^oC.
q = m x C_g x (T_f - T_i)
m = 250g
C_g = 4.18 J ^oC^-1 g^-1 (from table above)
T_f = 56^oC
T_i = 20^oC
q = 250 x 4.18 x (56 - 20)
q = 250 x 4.18 x 36
q = 37 620 J = 38 kJ

electricity and magnetism basic formula

2010-01-31T08:02:00.000-08:00

in magnetic materials, sources of magnetization are the electrons' orbital angular motion around the nucleus, and the electrons' intrinsic magnetic moment (see Electron magnetic dipole moment). The other potential sources of magnetism are the nuclear magnetic moments of the nuclei in the material which are typically thousands of times smaller than the electrons' magnetic moments, so they are negligible in the context of the magnetization of materials.

Online Periodic Table of elements

2010-01-31T07:17:00.000-08:00

The first periodic table was devised by Dmitri Mendeleev and published in 1869.The periodic table is now ubiquitous within the academic discipline of chemistry, providing an extremely useful framework to classify, systematize, and compare all of the many different forms of chemical behavior. The table has found wide application in chemistry, physics, biology, and engineering, especially chemical engineering. The current standard table contains 117 elements as of July 2009

Moment of inertia table and Formula List

2008-01-25T20:39:00.000-08:00

Moment of inertia, also called mass moment of inertia or the angular mass or MOI, Moment of inertia is the rotational analogue to mass, is a property of physics that indicates the relative difference in how easy or difficult it will be to set any object in motion about a defined axis of rotation, The moment of inertia plays much the same role in rotational dynamics as mass does in basic dynamics, determining the relationship between angular momentum and angular velocity, torque and angular acceleration.
