This question bank mirrors Paper 1, 2, 3 structure, covering key topics like mechanics, thermodynamics, and waves. Get instant solutions, detailed explanations, and build exam confidence with questions in the style of MYP examiners.
True or False: According to the textbook, condensation is defined as the transition from gas to liquid when water vapor cools specifically below its saturation point.
In the observation of Brownian motion, how does the size of the visible particles (such as smoke or pollen) generally compare to the size of the molecules (such as air or water) causing the motion?
In the proportionality for the rate of conduction, , what does the term represent physically?
Why does the example of diamond being an excellent thermal conductor but a poor electrical conductor serve as an important note in the study of heat transfer?
According to the particle model, why are particles below the surface of a liquid unable to evaporate?
If a hand is moved from hot water to lukewarm water, the hand feels cold. This sensation occurs because:
When considering the design of a cooling system for an electronics cabinet, why are cooling fans often positioned to create a flow of air across the components?
Under what general condition does sublimation typically occur for most substances?
On a phase diagram, what do the lines (boundaries) between the regions for solid, liquid, and gas represent?
When a substance undergoes a phase change from a liquid to a gas, which of the following best describes the change in the particles according to the particle model?
