Question

the melting point of an element is 5 times the melting point of radon. find the melting point of the element.
melting points of selected elements
chart: y - axis (degrees celsius) with values from -100 to 80, x - axis labels: mercury, radon, potassium; mercury bar at -39, radon bar at -70, potassium bar at 63

Explanation:

Step1: Identify radon's melting point

From the graph, radon's melting point is \(-70\) degrees Celsius.

Step2: Calculate the element's melting point

The element's melting point is 5 times radon's. So, multiply \(-70\) by 5: \(5\times(-70)= -350\)

Answer:

The melting point of the element is \(-350\) degrees Celsius.
