Q: The ratio of specific weight of a liquid to the specific weight of pure water at a standard temperature is called
  • A. density of liquid
  • B. specific gravity of liquid
  • C. compressibility of liquid
  • D. surface tension of liquid
Correct Answer: Option B - Specific gravity is defined as the ratio of specific weight of a liquid to the specific weight of pure water at a standard temperature. • Surface tension of a liquid is the property of liquid by virtue of which free surface of liquid at rest tries to minimize its surface area.
B. Specific gravity is defined as the ratio of specific weight of a liquid to the specific weight of pure water at a standard temperature. • Surface tension of a liquid is the property of liquid by virtue of which free surface of liquid at rest tries to minimize its surface area.
