(b) The triple point of water‚ 0.01 °C‚ and 611.73 Pa‚ is one of the primary fixed points on the Kelvin absolute temperature scale. (c) The volume coefficient for the thermal expansion of a solid is twice the linear coefficient for thermal expansion. (d) A temperature of 26.85 °C is the same as 300 K.

LM35 Precision Centigrade Temperature Sensors The LM35 series are precision integrated-circuit temperature sensors‚ whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ˚ Kelvin‚ as the user is not required to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not require any external calibration or trimming

rulers and people have the freedom to express views‚ freedom to organize and freedom to protest The French Revolution (French: Révolution française; 1789–99) was a period of radical social and political upheaval in French and European history. The absolute monarchy that had ruled France for centuries collapsed in three years. French society underwent an epic transformation as feudal‚ aristocratic and religious privileges evaporated under a sustained assault from liberal political groups and the masses

Rather than the relative temperature scales of Celsius and Fahrenheit‚ cryogenicists use the absolute temperature scales. These are Kelvin (SI units) or Rankin scale (Imperial & US units).

What are the differences between absolute advantage and comparative advantage? Absolute advantage and comparative advantage are two basic concepts to international trade and perhaps two most important concepts in international trade theory. Under absolute advantage‚ one country can produce more output per unit of productive input than another. With comparative advantage‚ if one country has an absolute (dis)advantage in every type of output‚ the other might benefit from specializing in and exporting

Absolute Advantage and Comparative Advantage According to the classic model of international trade introduced by David Ricardo (19th-century English economist) to explain the pattern and the gains from trade in terms of comparative advantage‚ it assumes a perfect competition and a single factor of production‚ labor‚ with constant requirements of labor per unit of output that differ across countries. The basis for trade in the Ricardian model is the differences in technology between countries. As

Absolute Poverty: Right from the 19th century‚ some researchers are trying to fix some yardstick for measuring poverty in precise terms. Ideally speaking such a yardstick would help us establish a fixed level of poverty‚ known as “poverty line” below which poverty begins and above which it ends. Such a yardstick is believed to be universal in character and would be applicable to all the societies. This concept of poverty is known as “absolute poverty”. Absolute poverty is often known as
