2 Chemical warfare What is Chemical Warfare: To understand chemical warfare you must first understand what a chemical agent is. A United Nations report from 1969 defines chemical warfare agents as " ... chemical substances‚ whether gaseous‚ liquid or solid‚ which might be employed because of their direct toxic effects on man‚ animals and plants ... ". This means basically that any chemical that is used to directly effect and harm a person‚ plant‚ or animal would be an act of chemical warfare

Objective:- The aim of this experiment was to find the molar mass of unknown volatile liquid under known temperature and pressure. Introduction Molar mass or gram molar mass is the mass of the substance under consideration without distinguishing whether a substance is an element ‚ a molecule or an ionic compound. These elements‚ molecules or ionic compound could be solid gas or liquid. The molar mass of gas or vapor could be measured if the gases obey the law of Ideal Gas . The mass of

Is glass a solid or a liquid "The idea that glass is a fluid is a very widespread myth." (Yvonne Stokes:1999‚Discover Magazine) This myth has survived for centuries because glass is such a confusing matter which cannot be compared to the three ordinary kinds of matter described in our particle theory of matter. Gasses contain free flowing molecules which are much further apart then liquids and gasses which removes the possibility of glass being a gas. A liquid however contains tighter bound molecules
