When some water is churned continuously, its temperature increases. In this process

When some water is churned continuously, its temperature increases; option [C]. This process involves the conversion of mechanical energy into thermal energy. The mechanical energy applied to churn the water causes friction and turbulence among the water molecules, increasing their kinetic energy. This increase in kinetic energy manifests as thermal energy, raising the water’s temperature. Therefore, the correct option is [C] Mechanical energy is converted into thermal energy. This phenomenon is consistent with the principle of energy conservation, where one form of energy (mechanical) is transformed into another form (thermal) without the net loss or gain of energy. Understanding these energy transformations is essential in various fields, including thermodynamics, fluid mechanics, and engineering, as it provides insights into the behavior of systems under different energy inputs and outputs. Overall, the conversion of mechanical energy into thermal energy during water churning demonstrates the fundamental relationship between mechanical work and heat transfer.
