महाराणा प्रताप ट्रेल सज्जनगढ़ उदयपुर

महाराणा प्रताप ट्रेल सज्जनगढ़ उदयपुर में इको ट्रेल 30 नवम्बर को राजस्थान वन विभाग उदयपुर डिविजन तथा WWF-India उदयपुर डिविजन के सानिध्य में महाराणा प्रताप ट्रेल सज्जनगढ़ उदयपुर में इको ट्रेल की गई, जिसमें WWF-India के स्टेट काॅर्डिनेटर श्रीमान अरूण सोनी तथा वन विभाग कीे ओर से डाॅ. सतीश कुमार शर्मा, सेवानिवृत्त अधिकारी मौजूद थे। मुझे भी इस इको ट्रेल में जाने का सुअवसर प्राप्त हुआ, जो गोरीला व्यू पाॅइंट से बड़ी-लेक व्यू पाॅइंट तक की गई इसमें मुझे विज्ञान की एक नई शाखा के बारे में पता चला, जिसे टट्टी विज्ञान कहा जाता है। सुनने में आपको थोड़ा अजीब लगेगा, मुझे भी सुनकर हैरानी हुई, परन्तु वास्तव में एक ऐसा भी विज्ञान है, जिसके बारे में डाॅ. सतीश शर्मा ने बड़े ही विस्तार पूर्वक बताया कि किस प्रकार वनों में जानवरों की टट्टी देखकर यह पता लगाया जा सकता है कि यहां कौनसा जानवर आया था। जानवरों की टट्टी कितनी पुरानी है, वह गीली है या सूखी है। इसी के आधार पर उस विशेष जंगल में कौन-कौनसे जानवर विचरण करते हैं, उसके बारे में वन विज्ञान के कर्मचारी पता लगा लेते हैं। जानवरों की टट्टी का विश्लेषण करके यह पता लगा...

Virial equation of state and Boyle temperature


    Ideal gas

  • An ideal gas is a gas which satisfy Boyles’ and Charles’ law for all the values of pressure, volume and temperature completely.
  • Equation of state of an ideal gas for 1 gm molecule or 1 mole is PV = RT.
  • In deriving this equation it was assumed that
  • The size of gaseous molecules are infinitely small, so they do not occupy any space.
  • There is no attractive or repulsive force between the gaseous molecules, so they have only kinetic energy, not potential energy.

  • Deviation from perfect gas equation

  • No gas is ideal or perfect, because no gas follow the ideal gas equation PV = RT at all conditions.
  • The gases which liquified easily show more deviation from the ideal gas equation.
  • For every gas there is a temperature at which the value of PV remain almost constant with increase in P and the value of PV increases at very high pressure. This particular temperature is known as Boyle temperature (TB).
  • Below TB, PV first decreases with increase in P, reaches to a minimum value and then increases with increase in P.
  • Above TB, the value of PV increases with increase in P from beginning.

    • Virial equation of state

  • PV = A + BP + CP2 + DP3 + ...

    • NOTE

  • The present lecture is a bilingual lecture, in which every step is explained in Hindi and in English language. Virial equation of state and Boyle temperature is very important in Thermodynamics. In the present lecture the Virial equation and Boyle temperature is explained in a well systematic way.

Electric field due to circular loop of charge | Electromagnetics

Electric field due to circular loop of charge Electric field The space around a charged particle in which another charge experience a force is known as electric field. The source of electric field is either a charge or a time varying magnetic field. If the value of electric field does not change with time, then it will be uniform electric field, otherwise it will be non-uniform electric field. Electric field due to circular loop of charge If λ is linear charge density, then the charge on d l dq = λ d l      ⇒     dq = (q / 2πa) d l Electric field at P due to charge dq Special cases When P lies at the centre of the loop i. e., r = 0, then E = 0 When P lies very far from the centre of the loop i. e., r >> a, then E = kq / r 2 In this case circular loop behaves as a point charge.

Cardinal points of a lens system | Optics | General theory of image formation

Cardinal points of a lens system There are total six cardinal points of a lens system, which are first and second focal points, first and second principal points, and first and second nodal points. First and second focal points (First and second focal planes) A pair of points lying on the principal axis and conjugate to points at infinity are known as focal points. First and Second focal points A point on the principal axis in the object space so that the rays starting (or appear to start) from it become parallel to the principal axis after refraction from the lens system is known as first focal point (F 1 ). A point on the principal axis in the image space so that the rays parallel to the principal axis in the image space focus (or appear to focus) at this point after refraction from the lens system is known as second focal point (F 2 ). First and Second focal planes The plane passing through the first focal point, and perpendicular to the optic axis is first f...
