PAPER 2 ESSAY [60 marks] Answer eight questions in all: five questions from Part I and three questions from Part II. PART I [15 marks] Answer any five questions from this part. All questions carry equal marks. 1. (a) Define the term momentum.

Here are the answers to the questions: 1. a) Momentum is defined as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction. Momentum = mass × velocity b) The device used to measure atmospheric pressure is a barometer. 2. a) Two properties of an ideal gas are: • The particles of an ideal gas have negligible volume compared to the volume of the container. • There are no intermolecular forces of attraction or repulsion between the particles of an ideal gas. b) The principle behind the construction of a simple hydrometer is Archimedes' principle. This principle states that the buoyant force on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. A hydrometer floats higher in denser liquids and lower in less dense liquids. Send me the next one 📸
