Specific gravity What is specific gravity? Archimedes discovered that the weight of body in air minus its weight in water is equivalent to the weight of the water displaced by the body. Specific gravity is defined as "The weight of a body compared with the weight of an equal amount of pure water at 4°C (4°C is the temperature at which water is densest). When a body is placed in water‚ the volume of water displaced is equal to the volume of the body. When the body is placed in water that it

Introduction: Specific gravity or relative density is the ratio of the density of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water. Temperature and pressure must be specified for both the sample and the reference. The following formula is used- Specific gravity= density of sample/density of same volume of water. Specific gravity is commonly used as a simple means of obtaining information about the concentration of solutions

We can sidestep this molecular picture by dealing with objects as a whole‚ and treating the energy transfer as the flow of heat‚ rather than kinetic energy transfer among particles. |Specific Heat for Various Materials | |Material |Specific Heat | | |(J/kg C°) | |Water |4186 | |Aluminum |900 | |Steel

Introduction An injunction is an equitable remedy in the form of a court order that requires a party to do‚ or to refrain from doing‚ certain acts. A party that fails to comply with an injunction faces criminal or civil penalties and may have to pay damages or accept sanctions. In some cases‚ breaches of injunctions are considered serious criminal offenses that merit arrest and possible prison sentences. Emergency injunctions that are in effect only a short time are called temporary restraining

In fact it is the objective of the maintenance function to maintain or increase the reliability of the operating system as a whole. Many steps can be taken to ensure that such an objective is achieved‚ but only a few of these are normally considered to be the responsibility of the maintenance department.

Introduction Specific heat is defined as the measure of the ability of a substance to change temperature. Specific heat of a substance is the heat needed to change the temperature of 1 gram of a substance once degree Celsius. The more Joules (unit of heat) needed‚ the higher the specific heat will be. The goal is to determine specific heat of a soil sample as compared to water. This difference has many ramifications regarding our climate‚ with local and global. Hypothesis I predict that after
