India and the British Empire In the 19th century, several European nations engaged in imperialism, expanding their influence globally. British East India Company's Dominance: The British East India Company, founded in the 1600s, gradually seized control over India, controlling more than half by 1857 . Modernization Efforts: Viewing India as crucial for trade, the British initiated modernization by constructing cities, roads, schools, and railways. Challenges in British-Indian Relations: Seeking economic gains, the British fostered a partnership with India, capitalizing on resources like indigo, cotton, and opium. Military Missteps: Introducing new rifles with cartridges containing animal fat sparked the Sepoy Mutiny in 1857, a significant rebellion against British rule. Cultural Misunderstandings: Despite attempts to comprehend Indian culture, misunderstandings and conflicts persisted, straining the relationship between the British and India. Why did the Sepoy Mutiny occur in 1857 ? The Indian soldiers were unhappy with the new modernization efforts. The British wanted to take control of India's resources. The British introduced rifles with animal fat cartridges, which offended Indian religious beliefs.

Theorem B. If $ \mu $ is a measure on a $ \sigma $-ring $ \mathbf{S} $, then the class $ \mathbf{S} $ of all sets of the form $ E \Delta N $, where $ E \varepsilon \mathbf{S} $ and $ N $ is a subset of a set of measure zero in $ \mathbf{S} $, is a $ \sigma $-ring, and the set function $ \bar{\mu} $ defined by $ \bar{\mu}(E \Delta N)=\mu(E) $ is a complete measure on $ \mathbf{S} $. The measure $ \bar{\mu} $ is called the completion of $ \mu $. Proof. If $ E \varepsilon \mathbf{S}, N \subset A \varepsilon \mathbf{S} $, and $ \mu(A)=0 $, then the relations and \[ E \cup N=(E-A) \Delta[A \cap(E \cup N)] \] \[ E \Delta N=(E-A) \cup[A \cap(E \Delta N)] \] show that the class $ \mathbf{S} $ may also be described as the class of all sets of the form $ E \cup N $, where $ E \varepsilon \mathbf{S} $ and $ N $ is a subset of a set of measure zero in $ \mathbf{S} $. Since this implies that the class $ \mathbf{S} $, which is obviously closed under the formation of symmetric differences, is closed also under the formation of countable unions, it follows that $ \mathbf{S} $ is a $ \sigma $-ring.

Q1) (25 pts) a. (12.5 pts) Evaluate the diffusion coefficient of carbon dioxide in air at 20 C and atmospheric pressure by selecting appropriate diffusivity parameter equation. b. (12.5 pts) Experimental value for CO2 in air at 273 K at 1 atm is obtained as 0.136 cm2/s. By using below given equation calculate the corresponding diffusivity parameter at 273 K and compare against the experimental value. $D_{ABT_2, P_1} = D_{ABT_1, P_1} \left(\frac{P_1}{P_2}\right) \left(\frac{T_2}{T_1}\right)^{3/2} \frac{\Omega_D |_{T_1}}{\Omega_D |_{T_2}}$ (Use MW$_{air}$ = 29 and MW$_{CO2}$ = 44, use Appendix B for $\sigma$ and $\epsilon/K$ values)
