The property of metal by virtue of which it melts when heat is applied: Correct Answer Fusibility

Concept:

Malleability
  • The ability of the material to deform to a greater extent before signs of crack appear when it is subjected to a compressive force.
  • It  is the property of a material by virtue of which a material can be rolled or hammered into thin sheets  

Hardness
  • Hardness is a measure of a metal's ability to withstand scratching, wear, and abrasion, indentation by harder bodies.

Fusibility
  • It is defined as the property of metal by virtue of which it melts when heat is applied.

Ductility
  • The capacity of a material to undergo deformation under tension without fracture in the material that property of a body is known as Ductility. E.g. Wire Drawing, etc.

A Carnot heat engine receives heat at 750 K and rejects the waste heat to the environment at 300 K. The net work output of the heat engine is used to drive a Carnot refrigerator, whose COP is 6.14. If the heat removal rate from the refrigerated space is 6.6 kW, determine the rate of heat supply to the heat engine?
To effect a bond between two metal plates, 2.5 cm and 15 cm thick, heat is uniformly applied through the thinner plate by a radiant heat source. The bonding must be held at 320 K for a short time. When the heat source is adjusted to have a steady value of 43.5 k W/m2, a thermocouple installed on the side of the thinner plate next to source indicates a temperature of 345 K. Calculate the temperature gradient for heat conduction through thinner plate. In the diagram, the upper plate is 2.5 cm thick while the lower is 15 cm thick.
