GED Science Sample Test - Question 2 of 10

The Zeroth law of thermodynamics states that if two substances of different temperatures are brought together, heat will transfer from the warmer substance to the cooler substance.

With this in mind, if a room-temperature spoon is placed into a hot cup of coffee, followed by a teaspoon of cream from the refrigerator, how would the temperature for these three elements change over time?

The coffee warms the spoon and creamer, but otherwise stays the same temperature.

All three elements—spoon, coffee, and creamer—will eventually equalize at the same temperature.

The spoon becomes much hotter, the coffee grows cold, and the cream remains about the same temperature.

The coffee and the creamer will balance each other out in temperature. The spoon will remain the same temperature.
