Thermal Energy Transfer and Equilibrium Practice Test

A student places a $25^\circ\text{C}$ glass beaker in direct contact with a $90^\circ\text{C}$ hot plate. The beaker is initially cooler than the hot plate, and they remain in contact until the beaker’s temperature stops changing. Which statement best describes the thermal energy flow while they approach equilibrium?

A student places a $40^\circ\text{C}$ steel sphere into a large bath of oil maintained at $20^\circ\text{C}$. The sphere is fully submerged, and the bath is large enough that the oil temperature remains essentially constant. After a long time, the sphere’s temperature becomes constant. At equilibrium, which statement best describes the thermal energy transfer between the sphere and oil?
