Final answer:
All objects left on a table overnight in a science lab, regardless of their material, will reach thermal equilibrium and have the same temperature by the next morning.
Step-by-step explanation:
When you leave objects like a block of wood, a dinner plate, a winter scarf, and a metal dissecting tray on a table overnight in a science lab, all objects will eventually come to the same temperature. This is due to the principle of thermal equilibrium, according to the zeroth law of thermodynamics. Each material may have different heat capacities and thermal conductivities, but given enough time, in a consistent environment without additional heat sources or sinks, they will all reach the same temperature. This is similar to how if you put ice into lukewarm water, eventually they reach the same temperature due to the transfer of heat energy.
