ANS:C - maximum height of flame (in mm) without causing smoking, when burnt in a standard lamp.

The smoke point of kerosene refers to the maximum height of flame (in millimeters) that can be achieved without causing smoking when the kerosene is burnt in a standard lamp. So, the correct option is:

• Maximum height of flame (in mm) without causing smoking, when burnt in a standard lamp.

1. Standard Wick Lamp: A standard wick lamp is a device used to burn kerosene or similar liquid fuels. It typically consists of a wick that draws fuel from a reservoir and burns it to produce light and heat.
2. Smoke Formation: When a fuel like kerosene burns inefficiently or incompletely, it can produce smoke. Smoke formation occurs when the combustion process is not optimal, often due to factors such as incomplete mixing of fuel and air, poor fuel quality, or improper adjustment of the burner.
3. Measurement: To assess the quality of kerosene or its suitability for use in lamps:
   • The kerosene is burned in a standardized setup.
   • The height of the flame is carefully monitored.
   • The maximum height of the flame that can be sustained without producing visible smoke is recorded.
4. Importance: The maximum height of flame without smoke is an important indicator of fuel quality and combustion efficiency. Higher quality kerosene or cleaner-burning fuels will produce a taller flame without smoking, indicating more complete combustion and fewer emissions of soot and particulate matter.
5. Application: This parameter is used in various contexts, including:
   • Household Use: Ensuring that kerosene used in lamps does not produce excessive smoke, which can lead to indoor air pollution and health issues.
   • Industrial Applications: Assessing the suitability of fuels for burners and combustion processes where smoke emissions need to be minimized for environmental or operational reasons.

ANS:A - Mahakali River

The Koshi River forms part of the international boundary between India and Nepal. Originating in the Tibetan Plateau, the Koshi River flows southeastward through Nepal before entering the Indian state of Bihar. It is one of the major rivers in the region, contributing significantly to the Ganges Basin. The river has historically played a crucial role in the geography and hydrology of the region, and its basin is vital for the agriculture and livelihoods of the people in both countries. The Koshi River, along with its tributaries, serves as a natural demarcation line between India and Nepal in certain areas, reflecting the historical and geographical ties that define the border between the two nations. This river's significance extends beyond its role in boundary formation, impacting the regional ecosystem, water resources, and cross-border cooperation between India and Nepal.
