To determine the final equilibrium temperature when the glass is placed in the water, we can use the principle of conservation of energy. The heat lost by the glass will equal the heat gained by the water. The equation can be set up as ( m_{glass} \cdot c_{glass} \cdot (T_f - T_{glass}) = - (m_{water} \cdot c_{water} \cdot (T_f - T_{water})) ), where ( T_f ) is the final temperature, ( T_{glass} ) is 75°C, and ( T_{water} ) is initially at room temperature (assumed to be around 25°C). Solving this equation will yield the final temperature of the system.
