Question
To get an idea of the small effect that temperature has on Archimedes’ principle, calculate the fraction of a copper block’s weight that is supported by the buoyant force in $0^\circ\textrm{C}$ water and compare this fraction with the fraction supported in $95.0^\circ\textrm{C}$ water.

The ratio of the buoyant force to the copper weight is greater at $0^\circ\textrm{C}$ than at $95^\circ\textrm{C}$ by a factor of $1.02$.
