Where should you put a barometer in your house? Because air pressure is basically the same indoors and out, a barometer can be placed inside or outside. For home use, hang a barometer on a wall in a place where people can read it conveniently. In most cases, this is an indoor wall, but outdoor […]
Are linear and angular momentum conserved separately?
Are linear and angular momentum conserved separately? Now, such an object can be assumed to have a constant mechanical energy. But that is only one part of the story. The fact is, since each linear and angular momentum of this object is conserved, the respective components of its linear and angular energy also would be […]
What is the ideal gas thermometer?
What is the ideal gas thermometer? In principle, we can measure the same temperature using any gas, so long as the constant operating pressure is low enough. When we do so, our device is called the ideal gas thermometer. The (very nearly) direct proportionality of two low-pressure real gas volumes contrasts with what we observe […]

Why do waves not transfer matter?
Why do waves not transfer matter? A wave transports its energy without transporting matter. Waves are seen to move through an ocean or lake; yet the water always returns to its rest position. Energy is transported through the medium, yet the water molecules are not transported. Do waves transfer mass? Waves transfer energy but not […]
What is the importance of isotopes in our daily life?
What is the importance of isotopes in our daily life? Radioactive isotopes have many useful applications. In medicine, for example, cobalt-60 is extensively employed as a radiation source to arrest the development of cancer. Other radioactive isotopes are used as tracers for diagnostic purposes as well as in research on metabolic processes. What means 2he? […]
Why can sound not travel through space?
Why can sound not travel through space? Sound does not travel at all in space. The vacuum of outer space has essentially zero air. Because sound is just vibrating air, space has no air to vibrate and therefore no sound. If you are sitting in a space ship and another space ship explodes, you would […]
What two things started Earth?
What two things started Earth? When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle and a solid crust. Why […]
