physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions. The transfer of energy can occur in a variety of ways‚ among them conduction‚radiation‚ and convection. The SI unit of heat is the joule. Heat can be measured by calorimeter‚ or determined indirectly by calculations based on other quantities‚ relying for instance on the first law of thermodynamics. In calorimeter‚ the concepts of latent heat and of sensible heat are used. Latent heat produces changes of

Job Safety Analysis or Job Hazard Analysis All employers have duty of care to individuals‚ staff‚ contractors or third parties in the workplace. It is also a legal requirement that organizations should document any health and safety risks that have been identified in the workplace. Equally‚ it is necessary to record the actions taken to reduce those risks What is a Job Safety Analysis or Job Hazard Analysis? One way to increase the knowledge of hazards in the workplace is to conduct

HEAT GENERATED IN APPLIANCES Why do some appliances produce more heat than the others? Most appliances with high power rating are heating appliances.The heating appliances has a heating element like resistors. The resistorsconvert electrical energy into light and thermal energy . It depends on the resistance of material if how much heat can be produced from electricity. Those devices who produced heat‚ the Nichrome wire is an element who is responsible for heating . when we say nichrome

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

growth that needs to be controlled can be found. While controlling bacterial growth‚ clusters of Gram Positive Cocci were found. It was found some ways to control bacterial growth were disinfection‚ sterilization‚ antisepsis‚ sanitization‚ moist and dry heat‚ filtration‚ and radiation; just to name a few. The specific method used for control depends on various circumstances. PROCEDURE First‚ you want to place your test tubes on the bench; one being an unknown labeled as GrowthLab1 and the other is
