QuestionWhat causes pressure? A. Heat conduction B. Bonding changes C. Phase conversion D. Molecule collisions
Studdy Solution
STEP 1
Assumptions1. We are asked to determine what causes pressure. . The options provided are Conduction of heat, Changes in bonding, Converting phases, and Collisions of molecules.
STEP 2
Pressure is defined as the force applied perpendicular to the surface of an object per unit area.
STEP 3
The force exerted by a gas (or any matter in a fluid state) on the walls of its container is due to the collision of its molecules with the walls of the container.
STEP 4
Therefore, the cause of pressure in this context is the collision of molecules.
The answer is D. Collisions of molecules.
