| Ans: |
bolometer - an instrument that measures heat radiation; extremely sensitive, calorimeter - a measuring instrument that determines quantities of heat, katharometer - measures thermal conductivity, Liquid crystal thermometer, thermometer – measures temperature, constant volume gas thermometer, constant pressure gas thermometer - measures temperature by the variation in volume or pressure of a gas, Pyrometer is any non-contacting device that intercepts and measures thermal radiation. |

What is heat? |

| Ans: |
Heat is a form of energy that is transferred from one object to another because of a temperature difference; the word transfer is important, because heat is often confused with thermal energy that is the property of a body related to internal energy. In addition, heat should not be confused with temperature, which is the degree of hotness of a body. In the absence of work, heat is always transferred from a body with higher temperature (hotter) to one with lower temperature (colder). |

| Q14: |
why liquid oxygen is used in space???? |
Alfa |
30/5/2007 |
| Ans: |
On Earth, oxidation uses atmospheric oxygen; in space, we take our own oxidizer. A rocket needs cheap, small storage, stable, incombustible but supporting combustion and highly energetic oxidizer. Liquid O2 meets the criteria. Gaseous oxygen is less dense & needs high tank volume but liquid oxygen being dense needs smaller tanks. It is a moderate cryogen -183 C (-297 F) so lesser insulation is needed. It gives the high specific impulse of 381 (less propellant is needed to gain a higher thrust). |

We are sorry but at present both the options are not there, we are considering them as many visitors request free download or free viewing. However you can view this online for as cheap as $2 for an hour by subscribing to it. This small subscription opens up the site and you can watch any animation on our site. What’s more is that any number of your friends can simultaneously watch this animation anywhere in the world, if you give them the key. A facility used by schools around the world. |

give me some question about heat |
enoin |
26/2/2007 |
| Ans: |
Thanks for the question; we were pleasantly surprised by it, so you want a question? How about, how is a building insulated from heat loss and gain? (This will involve wide research covering material, heat propagation mechanism and thermal insulation), we are developing an animation on it, we could use your research and give you credit for it. If you want a deeper topic look at “Phonon Transmission – (already released by us, but we need to revise it soon and hive it off as a separate product). |
