reading: The accelerometer keeps track of how quickly the speed of your vehicle is changing. When your car hits another car—or wall or telephone pole or deer—the accelerometer triggers the circuit. The circuit then sends an electrical current through the heating element, which is kind of like the ones in your toaster, except it heats up a whole lot quicker. This ignites the charge which prompts a decomposition reaction that fills the deflated nylon airbag (packed in your steering column, dashboard or car door) at about 200 miles per hour. The whole process takes a mere 1/25 of a second. The bag itself has tiny holes that begin releasing the gas as soon as it’s filled. The goal is for the bag to be deflating by time your head hits it. That way it absorbs the impact, rather than your head bouncing back off the fully inflated airbag and causing you the sort of whiplash that could break your neck. Sometimes a puff of white powder comes out of the bag. That’s cornstarch or talcum powder to…

Calorimetry of Metals Lab Set up a boiling water bath of 250 mL of water in a 400L beaker at 325 degrees C.  Placed a test tube of 13.88g of aluminum into boiling water.  Boiled for 20 minutes and reached a temp of 99.0 degrees C. Set up a "coffee-cup" calorimeter with a volume of 50mL of water.  Assume the water has a density of 0.997 g/mL.  Initial temp of 50mL of water is 22.2 degrees C.  Dumped the test tube of heated aluminum into calorimeter.  Final temp of 50mL of water is 26.4 degrees C.  Calculate the specific heat of the aluminum.  Use the specific heat of water as 4.184 J/g*degrees C.

(Would like answers for part B ONLY please-need info from part a to answer. I already solved part a) 1)Energy Efficiency at Home: ​Suppose you have two kettles – a plug-in electrickettle and a stovetop kettle. The electric kettle uses electricity from a natural gas fired powerplant, while you boil water in your stovetop kettle on a natural gas burner. a)Based on the following information, which of these kettles demonstrates a higher energy efficiency (i.e., which is more efficient at using energy from fuel to heat water)? Please calculate the efficiencies of each kettle and express answers as percentages. ​ -The natural gas power plant converts chemical energy of the natural gas to electrical energy with 58% efficiency. -High-voltage power lines from the power plant to your house convey electricity with 92% efficiency. -The electric kettle converts electrical energy to thermal energy in the water with 85% efficiency (the other 15% heats up the kettle itself). -The stove burner converts…

Numerous power plants and manufacturing facilities generate heat or operate at elevated temperatures. Frequently, the temperature is lowered by circulating water around the equipment and dumping the heated water into ponds or rivers. This can result in an increase in the temperature of the pond, river, or water supply used for discharge. The term "thermal pollution" refers to the process of increasing the temperature of these water sources. Thermal pollution can have a detrimental effect on the ecosystem, resulting in the death of fish and other aerobic organisms Using your knowledge of the effects of temperature on gas solubility, explain why elevated water temperatures can kill fish.
