Question

With the increases of temperature, the fluidity of liquids-
1. Increases
2. Decreases
3. Remains constant
4. No effect

Answer 1

Correct Answer - Option 1 : Increases

Explanation:

• Fluidity can also be defined as the length of the spiral covered by the molten metal before it gets solidifies.
• Pouring temperature is the most important controlling factor of fluidity.
• So the higher the pouring temperature, the higher the fluidity.
• The optimum temperature after melting is decided by a property called fluidity, of the metal.
• Fluidity refers to the relative ability of the liquid metal to fill in the mould at a given temperature.
• Fluidity is higher when viscosity is lower.
