Standard Model There are two types of building blocks to everything in the universe: fermions and bosons. Fermions are units of mass. Fermions are the building blocks which make stuff. Bosons are units of force. Bosons are the mechanisms of interaction and exchange. There are four different types of forces in the Standard Model: electromagnetic force‚ the strong force‚ the weak force and gravity. The electromagnetic force explains electricity‚ magnetism‚ and other electromagnetic waves including

Chemistry Quiz June 7‚ 2010 Name:_________________________________________ Score:______ 1. A sample of gas occupies a volume of 7.50 L at 0.988 atm and 28.0 °C. (a) Calculate the pressure of the gas if its volume is decreased to 4.89 L while its temperature is held constant. (b) At what temperature in degrees Celsius is the volume of the gas 4.0 L if the pressure is kept constant. 2. Calcium carbonate‚ CaCO3(s)‚ decomposes upon heating to give CaO(s) and CO2 (g). A sample of CaCO3

Hot air balloons might seem magical to some people because of its ability to float in the sky‚ but the process that allows them to take flight is actually very uncomplicated. The balloons are prime examples of the implementation of gas laws. The physics are based on the simple principle that warm air rises in cooler air. Hot air has less mass per unit of volume. The relevant gas law in use is Charless Law‚ which is V1/T1=V2/T2. The law states that raising the temperature (T1) will also increase

Title of the Experiment: determination of densities Introduction The density of a sample of matter represents the mass contained within a unit volume of space in the sample. For most samples‚ a unit volume means 1.0 ml. The units of density‚ therefore‚ are quoted in terms of grams per milliliter (g/ml) or grams per cubic centimeter (g/cm3) for most solid and liquid samples of matter. Density is often used as a point of identification in the determination of an unknown substance. The density

Health Promotion Reflection In this reflection I will be using Gibbs Model of Reflection (Jasper M‚ 2003). I will be talking about a patient who was advised to give up smoking‚ as part of promoting health to the patient but not directly linked to their illness and treatment. What Happened. I had a patient come into the ward who had had surgery‚ but this patient was overweight and a smoker which always effects the procedure and recovery. During the nights they had to sleep with a machine to

The clinical skill I have chosen to reflect on is the administration of Intramuscular (IM) injections. I will use a reflective model to guide me in my reflection. The Gibbs reflection cycle features‚ description‚ feelings‚ evaluation‚ description‚ conclusion and an action plan (Gibbs 1988). The first stage of Gibbs (1988) is description of events. On my clinical placement I had the opportunity to administer a drug to a patient via IM injection under the supervision of my mentor. I had already

The purpose of the lab was to find out the chemical elements based on the color of the flame that elements make by their reaction. The work we completed in the lab was testing the chemical effects of the flame from the chemicals. We tested different elements and wrote down our observations. I accomplished the knowledge of testing chemicals and making responses based on our observations.Electrons are the particles found in the chemicals that may be responsible for the production of colored light.
