Specific Heat

Specific Heat Purpose: The purpose of this laboratory experiment is to calculate "c" and the specific heat of the metal block. Materials: Tools: • (1) stirring bar • (1) wooden top • (1) tin cup • (5) S :: tin, aluminum, copper, lead and unknown  (1) calorimeter  (1) balance (1) Thermometer program: Before making measurements, create a table or chart that can be read and marked correctly. Clean the tin cup of the calorimeter.

It is called the heat of the object. Specific heat does not depend on the size and shape of the object, it depends only on the material making up the object. The specific heat of water is 1 calorie per gram of Celsius or 4,186 Joules per kilogram of Celsius. When it freezes, the amount of water increases and ice floats. This is related to the change in specific heat of water at around 0 ° C. Table 1 shows the specific heat of general materials. A system is a state of a system that can be changed. The change from solid to liquid or from liquid to gas or vice versa is called phase change. Even if the temperature of the material subject to phase change remains constant, they always accompany the transfer of heat.

High Specific Heat: The specific heat is the ability to absorb heat against temperature change. A large amount of heat (heat) can be absorbed and released without significantly changing the temperature if the specific heat of the substance is large. Hydrogen bonding in the water allows it to absorb and release heat only by slightly changing the temperature. Water buffers aquatic life as it does not need to withstand large temperature fluctuations. Water clarity: Most systems are not completely transparent, but allow light to penetrate the surface. Transparency is measured by turbidity, which is the opacity of water caused by suspended particles. Generally, the healthy water system has low turbidity. Light penetration is particularly important for photosynthetic organisms
