As gas and dust continue to fall inward in the disc, they give up energy to theprotostar, whichheats upmore When the temperature of the protostar reaches about 7 million degrees Kelvin,hydrogen begins tofuseto make heliumand release energy. Material continues to fall into the young star for ...
Explain how convection currents are produced in the air. How did Joseph Priestley create carbonated water? How do trace gases contribute to global warming? Why does vapor pressure increase with temperature? Why is gas exchange important? What happens to the volume of air as it rises? What happe...

Explain how heat energy is transferred by conduction, convection and radiation. What drives surface currents? Why does the high specific heat of water have to do with convection currents in the air at the seashore? Describe the typical path(s) for hurricanes. Is this part of the pattern of ...
Using a convection condition to prescribe the heat flux. Designers actually use this principle to introduce a fixed force into real-life mechanical components: a prestressed long weak spring. If the predefomation of the spring is much larger than the displacement of the parts to which the spring...
Science stores sell typhoon tubes to connect the two soda bottles instead of using duct tape. Ask your students to explain what they see. A convection current experiment relates to this project. Warning Securely fasten the two bottles or you will have liquid all over the place. ...
Hot oil is pumped from the top of the transformer through the heat exchanger (which cools it down) and back into the bottom, ready to repeat the cycle. Sometimes the oil moves around a cooling circuit by convection alone without the use of a separate pump. Some transformers have electric ...
In this early stage of Earth’s creation, theheaviest material like iron sank to the core. Lighter material remained on top to form a crust. Because the solid inner core heats the outer liquid layer, it produces convection currents. Thisgeodynamo is Earth’s magnetic field. Without it, Eart...
Various boundaries, such as the transition to high confinement, density limits, and power exhaust requirements, impose limits on the safe and efficient ope
How does a digital to analog converter work? Explain how convection currents are produced in the air. How does a gasoline internal combustion engine work? How does electric shock affect the human body? Why do magnets have a magnetic field?
