1. What property of matter determines its resistance to changes in shape or size?

Correct answer: A

Rationale: The correct answer is 'Solid.' Solids have a definite shape and volume, providing them with a strong resistance to changes in shape or size. Liquids and gases do not have a definite shape, making them prone to changing shape or size easily. Plasmas, on the other hand, are ionized gases with high energy levels and lack a definite shape or volume, which does not contribute to resistance against changes in shape or size. Therefore, the properties of solids make them best suited for resisting changes in shape or size compared to liquids, gases, and plasmas.

2. Which of the following arteries are not branches of the facial artery in the cervical portion?

Correct answer: C

Rationale: The correct answer is C, the Superior labial artery. It is a branch of the facial artery in the facial portion, not in the cervical portion. The ascending palatine artery, glandular artery, and tonsillar artery are branches of the facial artery in the cervical portion. The ascending palatine artery supplies the palate, the glandular artery provides blood to the salivary glands, and the tonsillar artery is responsible for supplying blood to the tonsils. These arteries play a crucial role in the vascular supply of the head and neck region, aiding in various physiological functions.

3. What is the formula to calculate acceleration?

Correct answer: D

Rationale: Acceleration is defined as the rate of change of velocity with respect to time. The correct formula to calculate acceleration is Acceleration = Time Change in Velocity. This formula specifically represents how much an object's velocity changes over a specified time period, providing a measure of the object's speed change rate. Choices A and B are incorrect as they do not represent the relationship between acceleration and time change in velocity. Choice C is incorrect as it involves time and distance, which are not directly related to acceleration.

4. What is the best tool to measure the volume of a solid?

Correct answer: C

Rationale: A graduated cylinder is the most suitable tool to measure the volume of both liquids and solids. It works by measuring the displacement of water when the solid is submerged in the graduated cylinder. Choice A, the triple beam balance, is used to measure mass, not volume. Choice B, using a measuring wheel and mathematical formula, is typically used to measure distance or area, not volume. Choice D, a measuring wheel, is used to measure distance, making it inappropriate for measuring the volume of a solid.

5. Which of the following is an example of a secondary alcohol?

Correct answer: C

Rationale: Isopropanol is indeed an example of a secondary alcohol because the carbon atom bearing the hydroxyl group is bonded to two other carbon atoms. In isopropanol, the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. Methanol (Choice A) is a primary alcohol with the hydroxyl group attached to a carbon atom that is bonded to one other carbon atom. Ethanol (Choice B) is also a primary alcohol with the hydroxyl group attached to a carbon atom that is bonded to one other carbon atom. Butanol (Choice D) is a primary alcohol with the hydroxyl group attached to a carbon atom that is bonded to three other carbon atoms, making it a primary alcohol.
