Question

A reaction is occurring in a test tube. How is heat transmitted to the surroundings?
A. As bubbles are formed and gas escapes, the heat is carried with the rising bubbles
B. Heat is carried out with matter as matter is changed with the surroundings
C. All of the heat escapes out of the open top of the test tube as molecules collide with the air
D. Molecules collide with the glass, and the glass molecules then transmit that energy to the outside

The correct answer is **D. Molecules collide with the glass, and the glass molecules then transmit that energy to the outside**.

In a test tube, heat can be transmitted to the surroundings through conduction. When the molecules of the reacting substances collide with the glass of the test tube, they can transfer their kinetic energy to the glass. The glass, being a solid, can then transfer this energy to the surrounding air through further collisions, thereby transmitting heat to the environment. Other options may involve some heat transfer, but option D specifically describes the effective conduction process in this scenario.
