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.
