Cool summer foods to beat the heat. Maintaining a healthy diet in summer is a concern for most individuals in the modern world. The sun is shining and the mercury levels are soaring‚ you know the summer is here and there is no escape from it. It is a season where energy levels and appetite are low and a slightest activity causes the sweat to flow off your back and face. Life goes on and it is very necessary to cope with the heat to avoid the usual problems of dehydration‚ heatstroke and a feeling

The Little Heat Engine: Heat Transfer in Solids‚ Liquids and Gases The question now is wherein the mistake consists and how it can be removed. Max Planck‚ Philosophy of Physics‚ 1936. While it is true that the field of thermodynamics can be complex‚1-8 the basic ideas behind the study of heat (or energy) transfer remain simple. Let us begin this study with an ideal solid‚ S1‚ in an empty universe. S1 contains atoms arranged in a

is the perfect introduction of us. During summer season prickly heat is irritating and painful problem for many. It is also termed as Miliaria or heat rashes. It is a skin disease marked by small and itchy rashes. When the sweat accrues in certain parts of our body and results in the formation of small red bumps‚ which causes irritation and severe itching‚ then trying out prickly heat powders is a very possible solution. Prickly heat mostly affects back‚ underarms‚ near waist area‚ and chest. Newborns

Calorimetry and Specific Heat Tessa Williams Chemistry 111 11/13/13 Abstract: In this experiment‚ the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. The average specific heat of the unknown metal was 0.197˚C and was determined using a calorimeter. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Using the specific heat value of the unknown metal and its density‚ it

In part A of the experiment the two values obtained for the specific heat capacity of the metal were about .0500 J/mol. This is a large deviation‚ with both of these values identifying very different metals. The average heat capacity identified the metal used as brass. The average heat capacity calculated was .3776 J/mol and the actual heat capacity of brass is .375 J/mol. The second run displayed the closest value to the actual value. A source of error that may have caused a large divide in the

Materials: Calorimeter Celsius Thermometer Platform balance Kettle Milk ice cubes Stopwatch Hot Water Procedure: The copper cup was weighed and its mass was then recorded. The kettle was then used to boil water and this water was poured into the copper cup. The mass of the cup plus the hot water was calculated and recorded. The copper cup was then placed in the insulated container. The water’s temperature was
