An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example‚ the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system: if the system is divided in half‚ the mass and the volume change in the identical ratio and the density remains unchanged. According

Customary Rights. A legal right is one that is enforceable by law. Any citizen and can discover these rights. They can validly be argued in court and generally take preference to other rights. Moral rights are those that particular groups believe are right and just. They are generally derived from religion and reflect the values and attitudes of the group that holds them. Usually the moral rights held by the majority of the population are closely reflected in their legal rights. Moral rights vary depending

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is

A detailed explanation‚ one paragraph or more in your own words‚ of the colligative property being discussed and why that property changes the way that it does when the amount of solute is increased. A detailed description‚ at least one paragraph‚ of a real-world application of the colligative property‚ including an explanation of how this application of the colligative property is important or useful to those affected. The real-world example must be one that was not mentioned in the lesson. An

Lightning is not distributed evenly around the planet‚ as seen in the image on the right. About 70% of lightning occurs over land in the tropics where atmospheric convection is the greatest. This occurs from both the mixture of warmer and colder air masses‚ as well as differences in moisture concentrations‚ and it generally happens at the boundaries between them. The flow of warm ocean currents past drier land masses‚ such as the Gulf Stream‚ partially explains the elevated frequency of lightning
