change its temperature by one degree‚ and has units of energy per degree. The heat capacity is therefore an extensive variable since a large quantity of matter will have a proportionally large heat capacity. A more useful quantity is the specific heat (also called specific heat capacity)‚ which is the amount of heat required to change the temperature of one unit of mass of a substance by one

Calculate the energy change (q) of the surroundings (water) using the enthalpy equation qwater = m × c × ΔT. We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. The water has absorbed the heat of the metal. So‚ qwater = qmetal Using the formula qmetal = m × c × ΔT‚ calculate the specific heat of the metal. Use the data from your experiment for the metal in your calculation. Aluminum: q=26*4.18*6.3=684.684‚ c=q/(m*^T)=3.913

October 1‚ 2012 Should There Be a Ban on Specific Dogs? There are plenty of different breeds of dogs that could be considered dangerous. The main targeted breeds are breeds such as Pit bulls‚ Rottweilers and German shepherds. According to the American Humane Association‚ an organization founded in 1877 dedicated to the welfare of animals and children‚ “An estimated 4.7 million dog attacks occur in the U.S” (5). Some people argue that a ban on specific dog breeds is the answer to this problem.

specific heat of solids 1. Introduction Heat capacity of a body is the quantity of heat required to raise the temperature of the body by 1oC. The specific heat of a substance is the heat capacity per unit mass. Thus‚ heat capacity = mass x specific heat. The specific heat is essentially a measure of how thermally insensitive a substance is to the addition of energy. Heat and temperature are really different quantities. Heat is a quantity of thermal energy‚ while temperature determines the

Arguments for pit-bull should be banned People generally want Pit Bulls and other Bully breeds banned for 2 main reasons: 1. Thugs who need a tough dog to feel tough intentionally doing everything they can to make their dogs mean. This includes‚ beating‚ starving‚ baiting‚ feeding weird crap like gunpowder....They also never socialize‚ train‚ or neuter their dogs. This intentionally creates a dog that is both dog and human aggressive and will most likely kill other pets and end up being

DP Physics IA Thermal physics: Specific Heat Capacity of Metals Introduction: In this experiment we are going to measure the specific heat capacity of a unknown metal. To measure the specific heat capacity we will heat up the metal to certain temperature and release the metal in beaker filled with water. By knowing the mass and temperature of water filled in beaker‚ we will be able to calculate the specific capacity of unknown metal by change in temperature of beaker willed
