Germain Henri Hess (August 7‚ 1802–November 30‚ 1850) was a Swiss-born Russian chemist and doctor who formulated Hess’s Law‚ an early principle of thermochemistry. Born in Geneva‚ Switzerland‚ his father was an artist and in 1805 moved the family to Russia to find work. Beginning in 1822‚ Hess studied medicine at the University of Tartu. He qualified as a physician in 1825. Hess turned to chemistry after a meeting with Jöns Jakob Berzelius‚ the famous Swedish chemist‚ and went to Stockholm University

Thump! Thump! Thump! Thump! This is the sound one is typically used to hearing and feeling when the pulse is racing out of control: whether of fear‚ anxiety‚ nervousness‚ etc. When one is generally watching/reading a horror movie/story‚ the person’s anticipation level is over the moon with wanting to know what is going to occur next. This certain genre is known to be based on humanity’s disturbing‚ inner thoughts that are kept hidden by sophistication and a civilized illusion. This category is for

The role of women in different societies and times in "Heat and Dust" The era of the Victorian women spanned 64 years and concluded several changes in attitudes. The common thinking about women in the Victorian era was that a woman´s position was limited to domestic work and the care for her children. The stereotype of the distribution of roles was women staying by the hearth with their needles whilst men wielded their swords. Women had to bear a large family and to maintain a smooth family atmosphere

theory of the experiment is that an object needs an amount of heat for it to change a unit mass by 1 degree in temperature. The objectives of the experiment are to determine the specific heat of metal specimens using the method of mixture‚ to measure the equipment properly‚ to carefully measure the temperature of the equipment‚ to be patient while waiting for the output of the experiment and to be precise in computing for the specific heat of the specimen.

Thermochemistry Thermochemistry is the study of heat evolved and absorbed during the chemical reactions. The system is the interest of the universe; the surroundings are the rest of the universe in which the exchange of the energy with the system takes place. Both‚ the system and the surroundings make up the universe. Heat flow is the transfer of heat from a warm place to a cooler one. System to surroundings: Surroundings to system:

Refrigerators‚ etc) - first law of thermodynamics heat added to a closed system goes into the internal energy of the system and/or doing work - H= delta E1 + W - a heat engine takes heat from a high temperature reservoir‚ converts some to useful work and rejects the remainder to the low temp reservoir. - Second law of thermodynamics - It is impossible for heat to flow spontaneously from a

Background Information: Heat is energy that transfers from one object to another because of a temperature difference between the objects. Heat is measured in a calorimeter and the units for heat are joules or calories. The calorimeter uses the Law of Conservation of Energy which states that energy is never created or destroyed but is transferred between objects. Temperature is a measure of the average kinetic energy of the particles an object which is different that the heat which is all the energy
