Chemical Physics

Chemical physics involves chemistry and physics in the investigation of the physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics. Chemical physics studies chemical processes from a physicist’s point of view. Although names are similar, chemical physics is different from physical chemistry due to the fact chemical physics studies the characteristic elements and theories of physics. Physical chemistry studies the physical nature of chemistry.

Chemical physics is a subset of the fields in quantum mechanics, solvation of molecular energy flow and quantum dots. Chemical physicists probe structures and dynamics of ions, free radicals, clusters, molecules and polymers. They do these probing experiments by various spectroscopic techniques. Chemical physics is an interdisciplinary field. The research areas include, DNA interactions, electrochemistry of semiconductors, fuel cells, ultrasound medical imaging and catalyst development to name a few. A chemical physicists' goal is to understand chemical structures and reactions at a quantum mechanical level. The goal is to make accurate approximations in physics of chemical phenomena computationally accessible.

Water, Osmosis, Cellular Function, and Turgor Pressure

Review physical and chemical properties of water. How might changes in temperature affect cellular function? How might water pollution affect cellular function? How might it affect water movement in cells and plants? OR What are roles of osmotic potential or turgor pressure in regulating water potential of plant cells? Exp

Physics: Calculate the PV work that is done ON the system

1.) What is the PV work that is done ON the system when a.) 20J of PV work is done on the surroundings W(system)= b.) one mole of gas is generated in a chemical reaction at 0 Celsius and 1 atmospheric pressure c.) A chemical reaction occurs where the volume decreases by 600L

A Discussion on Various Chemical and Physical Science Concepts

1. The density of the liquid flowing through the horizontal pipe in the drawing above is 1500 kg/m3. The speed of the fluid at pint A is 5.5 m/s while at point B it is 8.0 m/s. What is the difference in pressure, PB - PA, between points B and A? a.) -1.9 x 103 Pa b.)+3.8 x 103 Pa c.)-2.5 x 104 Pa d.)+5.0 x 104 Pa e.)-7.

Spectroscopy and Ferroelectrics

James made ferroelectrics sample (Bi, La)4Ti3O12 which has a crystal structure like Figure 1 (see attachment). Basically it was a material of the chemical composition of a Bi4Ti3O12, but it has been made by partly substituting La for Bi. He decide to do some analysis: 1. To confirm whether composition is right or not, what kind

Multiple choice questions relating to heat, gas and chemical equilibirums

The Greek word for "moving" is: (a) kinetic (b) atom (c) potential (d) force If two systems are in thermal equilibrium with a third system, then they are in thermal equilibrium with each other. This postulate is called: (a) first law of thermodynamics (b) second law of thermodynamics (c) third law of thermodyna

Bromine and radiation energy

Bromine has two natural isotopes, BR-81 (49.5%) and Br-79 (50.5%) a) What are the atomic numbers and neutron numbers of these isotopes? b) Use this information to explain why the atomic weight of chlorine is 79.9 Br-80 decays by beta emission with a half-life of 17.6 minutes a) Write down the decay equation showing the dau

Particle Physics

1. In an electrolysis experiment, a student plated silver onto an electrode, maintaining a current of 1.600 A for 46.0 min. What mass of silver was deposited? a. 4.94 g b. 2.47 g c. 11.2 g d. .02 g 2. A sample of polonium has a half-life of 2.7 min and an intial activity of 1.0 x 10^6 Bq. What is its act

Multiplicity for an ideal monatomic gas.

In problem 2.26 you found the multiplicity for an ideal monatomic gas that lives in a two-dimensional universe. It was (see attachment). As implied, the multiplicity is determined by the internal energy, the area occupied by the gas, and the number of particles in the gas. From these, determine the temperature, 'pressure', an

Quantimum number

An electron state in the hydrogen atom can be designated by the quantum numbers n, l, m and s a. Whet is the physical significance of each quantum number b. Describe how these numbers can be used to assemble the periodic table. c. Find the normalization constant and <r> for state n=2, l=1, m=0 See attached file for full
