The correct Answer is:
To determine the best distinguishing feature of thoracic vertebrae from the given options, let's analyze each option step by step: ### Step 1: Understand the Thoracic Vertebrae - The thoracic vertebrae consist of 12 vertebrae in the human body, labeled T1 to T12. They play a crucial role in forming the rib cage. ### Step 2: Analyze Each Option 1. **Larger Transverse Processes**: - While thoracic vertebrae do have transverse processes, they are not larger compared to other vertebrae. They are of intermediate size and have facets for rib articulation. Therefore, this option is not a distinguishing feature. 2. **Spinous Process Directed Posteriorly**: - The spinous process of thoracic vertebrae is indeed directed posteriorly, but this characteristic is also found in other vertebrae (like lumbar vertebrae). Thus, it cannot be considered a unique feature. 3. **Articulate with the Ribs**: - This is a unique feature of thoracic vertebrae. They have facets on their bodies and transverse processes that specifically allow them to articulate with the ribs, forming the rib cage. This is a key distinguishing characteristic. 4. **Absence of Vertebral Transverse Foramen**: - While thoracic vertebrae do lack transverse foramina, this feature is also true for other vertebrae types, except cervical vertebrae. Therefore, it is not exclusive to thoracic vertebrae. ### Step 3: Conclusion - After analyzing all the options, the best distinguishing feature of thoracic vertebrae is **Option 3: They articulate with the ribs**. This feature is unique to thoracic vertebrae and is essential for the structure of the rib cage.

Hanumappa and his wife Gangamma are busy making jaggery out of sugarcane juice. They have processed the sugarcane juice to make the molasses, which is poured into moulds in the shape of a frustum of a cone having the diameters of its two circular faces as 30 cm and 35 cm and the vertical height of the mould is 14 cm (see Fig. 13.22). If each cm^3 of molasses has mass about 1.2 g, find the mass of the molasses that can be poured into each mould. (Take π = 22/7 )

An aluminium wire of cross-sectional area (10^-6)m^2 is joined to a steel wire of the same cross-sectional area. This compound wire is stretched on a sonometer pulled by a weight of 10kg.

Dependence of Spontaneity on Temperature: For a process to be spontaneous , at constant temperature and pressure , there must be decrease in free energy of the system in the direction of the process , i.e. DeltaG_(P.T) lt 0. DeltaG_(P.T) =0 implies the equilibrium condition and DeltaG_(P.T) gt 0 corresponds to non- spontaneity. Gibbs- Helmholtz equation relates the free energy change to the enthalpy and entropy changes of the process as : " "DeltaG_(P.T) = DeltaH-TDeltaS" ""..."(1) The magnitude of DeltaH does not change much with the change in temperature but the entropy factor TDeltaS change appreciably . Thus, spontaneity of a process depends very much on temperature. For endothermic process, both DeltaH and DeltaS are positive . The energy factor, the first factor of equation, opposes the spontaneity whereas entorpy factor favours it. At low temperature the favourable factor TDeltaS will be small and may be less than DeltaH, DeltaG will have positive value indicated the nonspontaneity of the process. On raising temperature , the factor TDeltaS Increases appreciably and when it exceeds DeltaH, DeltaG would become negative and the process would be spontaneous . For an expthermic process, both DeltaH and DeltaS would be negative . In this case the first factor of eq.1 favours the spontaneity whereas the second factor opposes it. At high temperature , when T DeltaS gt DeltaH, DeltaG will have positive value, showing thereby the non-spontaneity fo the process . However , on decreasing temperature , the factor , TDeltaS decreases rapidly and when TDeltaS lt DeltaH, DeltaG becomes negative and the process occurs spontaneously. Thus , an exothermic process may be spontaneous at low temperature and non-spontaneous at high temperature. For the reaction at 25^(@), X_(2)O_(4)(l) rarr 2XO_(2)(g) DeltaH=2.1 Kcal and DeltaS = 20 cal K^(-1) . The reaction would be
