Statement I: Materials that allow heat to pass through them easily are called conductors. Materials that resist the flow of heat are called insulators. Therefore, the statement incorrectly defines insulators. Statement II: Clinical thermometers are specifically designed to measure the temperature range of the human body. A typical clinical thermometer has a scale ranging from 35°C to 42°C or slightly extended, like 32°C to 42°C, to cover possible variations in body temperature during health and illness. The stated range of 32°C to 42°C is a standard range for clinical thermometers.
