Explanation

• The average normal body temperature is generally accepted as 98.6°F (37°C).
• A temperature over 100.4°F (38°C) means you have a fever.

Additional Information:

• Hypothermia is the term used for temperature less than 36.50°C.
• Mild Pyrexia is the term used for temperature (99-100°F).
• Moderate Pyrexia is the term used for temperature (100-103°F).
• Severe Pyrexia is the term used for temperature (103-105°F).

Explanation

• Conductors are materials that allow electricity to flow through them, such as copper, aluminum, and gold.
• They have a high concentration of free electrons, which are able to move freely within the material.

Additional information:

• Materials that do not allow electricity to pass through them are called insulators.
