Answer:
The answer is explained below.
Step-by-step explanation:
The melting point is a physical property of a substance and is the temperature at which the material changes from a solid to a liquid state at atmospheric pressure.
Melting point of copper
The melting point of copper (Cu) with atomic number 29 is 1,085 °C
Safety concerns associated with the use of copper
- Excess copper inhibits plants growth.
- Copper can affect the activity in soils, as it negatively influences the activity of microorganisms and earthworms.
- Exposure of the body to copper can irritate the skin and eyes.
- Copper may negatively affect the liver and kidneys.
- Copper is also known to cause vomiting, headaches and dizziness when exposed for long.
Melting point of sulfur
The melting point of sulfur (S) with atomic number 16 is 115.2 °C
Safety concerns associated with the use of sulfur
- Long term exposure Increases susceptibility to respiratory infections.
- Ingesting too much sulfur may cause diarrhea and blurred vision.
- Chronic exposure can affect the sense of smelling.
- If animals eat too much sulfur, it may affect the stomach and intestines, and cause neurological disorders.
- Prolonged inhalation exposure may cause severe breathing difficulties.
- Thermal burn from molten sulfur when in contact with the skin, can cause dryness, mild irritation.
- Sulfur in excess can cause brain cell death.
