Question

There is no effect of temperature on ……………....type of materials​

Answer 1

Answer:

Metals are elements or compounds with excellent conductivity for both electricity and heat, making them useful for a wide range of practical purposes. The periodic table currently contains 91 metals, and each has its own specific properties. The electrical, magnetic and structural properties of metals can change with temperature and thereby provide useful properties for technological devices. Understanding the impacts of temperature on the properties of metals gives you a deeper appreciation for why they're so widely-used in the modern world.

Temperature affects metal in numerous ways. A higher temperature increases the electrical resistance of a metal, and a lower temperature reduces it. Heated metal undergoes thermal expansion and increases in volume. Increasing the temperature of a metal can cause it to undergo allotropic phase transformation, which alters the orientation of its constituent atoms and changes its properties. Finally, ferromagnetic metals become less magnetic when they can get hotter and lose their magnetism above the Curie temperature.

Answer 2

Answer:

Molality

Explanation:

molality is not affected by temperature because volume does not involve in molality which changes with temperature.
