Explanation:
To determine whether a metal with a hardness of HRC50 is softer or harder than a metal with a hardness of HRC30, we need to understand the meaning of HRC (Hardness Rockwell C) values.
The Rockwell hardness test measures the hardness of a material by applying an indenter, usually a diamond or a steel sphere, to the material and measuring the depth of penetration. The Rockwell hardness scale assigns a hardness value to the material based on this measurement.
On the Rockwell C scale, a higher value indicates a harder material. Therefore, a metal with a hardness of HRC50 is harder than a metal with a hardness of HRC30.
Based on this information, the statement "A metal with a hardness of HRC50 is softer than a metal with a hardness of HRC30" is false.
