To find the percentage change in upthrust when a solid ball is immersed in a liquid and the temperature is increased by \(25^\circ C\), we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Upthrust (Buoyant Force)**: The upthrust (buoyant force) \( F_{\text{up}} \) acting on the ball is given by the formula: \[ F_{\text{up}} = V_B \cdot \rho_L \cdot g ...
