Ten Minutes of Specific Heat Remi Adams East Rowan High School AP Environmental Science Abstract Specific heat and climate were the primary focus of this lab. Specific heat is defined as “the measure of the ability of a substance to change temperature”. The purpose for carrying out this lab was to determine the specific heat/rates of both soil and water‚ and then comparing them. Students also were to relate specific heat to climate. Students were to determine which substance expressed

our lives would be very different. The light bulb is a very useful invention that people all over the world use every day. The creation of the light bulb can be traced back to the 19th century. In 1800‚ Humphrey Davy made the arc lamp (“Lighting”). But the arc lamp was very dangerous because light was made by sparks‚ increasing the chance of fire (Burnie 52). In 1860‚ Joseph Swan made an incandescent light bulb. But the light bulb had many disadvantages. The light bulb burned out in an hour and

Their vision is to see the people of the rural parts of Indonesia to think green and use solar lamps instead of kerosene lamps that causes hundreds of accidents every month. The mission is to replace at least half (roughly 16 million units) of these kerosene lamps in Indonesia with environment-friendly solar lamps. The solar lamps range from reading lights to streetlights. Therefor

There are several disadvantages to Induction light sources as compared to LED fixtures: 1. The Induction system requires 3 components‚ the generator‚ the power coupler and the lamp. All three components are almost always supplied as a system and the manufacturers highly recommend replacing all three every relamp
