Subject:Chemistry Topic:States Of Matter What is matter? Matter is anything that has mass and occupies space. All matter can exist in three(3)states. There are: solid‚ liquid and gas. In addition‚ all matter is made up of particles: atoms‚ molecules and ions. Solids In the solid state state‚ the particles are packed closely together in a regular manner. The focus of attraction between these particles are very strong and as a result solids are usually very hard and very difficult to compress

The market is currently saturated with a variety of hair extensions that come from different countries - Brazilian‚ Peruvian and Indian‚ are just to name a few. With so many different types of extensions‚ it can be difficult to know how distinguish between them‚ or even how to properly care for them. To keep things simple‚ these types of hair extensions are also known as virgin hair. The name derives from the fact that these high quality extensions have never been processed. Regardless of the hair

Why does snow melt in the sun at temperatures below freezing? The rate of snow melt is dependent on energy availability‚ which is mostly in the form of radiation. Cold snowpacks have a negative energy balance‚ but warming causes the snowpack to become isothermal and additional energy results in positive energy balance and melt. Daily snow melt in forested areas is considerably less than melt in open areas‚ as forests protect the snow cover from solar radiation and wind. Canopy warming can increase

A steel link‚ with no internal stresses‚ is pinned between two solid structures at a reference temperature of 0 C (273 K). One of the solid structures is heated to a temperature of 75 C (348 K). As heat is transferred

INTRODUCTION Worldwide postharvest fruit and vegetables losses are as high as 30 to 40% and even much higher in some developing countries. Reducing postharvest losses is very important; ensuring that sufficient food‚ both in quantity and in quality is available to every inhabitant in our planet. Proper postharvest processing and handling is an important part of modern agricultural production. Postharvest processes include the integrated functions of harvesting‚ cleaning‚ grading‚ cooling‚ storing

CHEM161 Experiment 7: Calorimetry Introduction Calorimetry is the science of measuring heat flow‚ and heat is defined as thermal energy flowing from an object at a higher temperature to one at a lower temperature. For example‚ if a chunk of metal at room temperature is placed in a beaker of boiling water‚ the metal will absorb heat from the water until it is at the same temperature as the boiling water. Scientists also often study the heat associated with different physical and chemical changes
