Recycling has many advantages. It can tackle environmental problems‚ save energy while reduce waste and turn the wastes into treasures. Above everything else‚ recycling can tackle environmental problems. A winning invention which is a solar water heater making by plastic bottles and milk cartons is cheap‚ simple and widely used. It not only solves the problems in Brazil but also has benefits for people. The inventor‚ Jose Alano‚ only want to reuse the waste and make contributions to the environment

The effect of different temperature on the cell respiration. Introduction： Cell respiration is the controlled release of energy from organic compounds in cells to form ATP‚and then release waste products. The process of cell respiration can take place in the presence or absence of oxygen. In either case‚the first stage of cell respiration is glycolysis.The effect of temperature on cell respiration mainly depends on the effect of temperature on of enzyme activity.Generally speaking in a certain

A voltage ΔV is applied across the ends of a nichrome heater wire having a cross-sectional area A and length L. The same voltage is applied across the ends of a second heater wire having a cross-sectional area A and length 2L. Which wire gets hotter?

Heat pump From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search For theoretical background‚ see Heat pump and refrigeration cycle. Outdoor components of a residential air-source heat pump A heat pump is a machine or device that transfers thermal energy from one location‚ called the "source‚" which is at a lower temperature‚ to another location called the "sink" or "heat sink"‚ which is at a higher temperature. Thus‚ heat pumps moves thermal energy opposite to the direction that

The proper temperature in a saltwater fish tank‚ no matter how many gallons it is‚ is 77 degrees. This is because that probably the temperature the fish and coral were kept at‚ when they were at the fish store you purchased them from. If you have a larger fish tank‚ you should have at least two heaters. Lighting is very important in your saltwater fish tank. Not only
