Wisconsin CNA State Exam Vocabulary Practice

What physical property expresses how hot or cold water is?

1. A. Weakness

2. B. Weighing

3. C. Walker

4. D. Water temperature

The correct answer is: D. Water temperature

The correct answer is water temperature, as it specifically refers to the measurement of how hot or cold water is. Temperature is a fundamental physical property that quantifies the thermal energy of a substance, indicating the average kinetic energy of its molecules. In practical and clinical settings like that of a CNA, understanding water temperature is essential for tasks such as bathing a patient or preparing warm compresses, as it ensures safety and comfort. The other options do not pertain to the measurement of hot or cold. Weakness refers to a physical or emotional state, weighing pertains to the measure of mass, and walker is unrelated, as it refers to a mobility aid. Therefore, water temperature is the only choice that accurately describes the property in question.
