Final answer:
Different substances react differently to changes in temperature due to varying thermal expansion coefficients and specific heat capacities. An object with a higher thermal expansion coefficient will experience more stress when heated identically to one with a lower coefficient. The process of salt causing ice to melt and refreeze, binding a thread to an ice cube, demonstrates latent heat.
Step-by-step explanation:
Regarding the statement "Do they react the same way as wt at different temperatures?", without clear context, one can infer that it may involve how different substances or materials (they) behave under temperature changes compared to a known standard or control (wt, possibly referring to wild type in a biological context).
In terms of thermal expansion and latent heat, different materials will not react the same way to temperature changes. For example, two objects with identical dimensions but made from materials with different thermal expansion coefficients will experience different amounts of expansion and potential stress when heated identically. A material with a higher thermal expansion coefficient will expand more upon heating, potentially resulting in greater stress within the material if it is constrained. Similarly, substances with different specific heats will absorb or release different amounts of energy for a given temperature change. When salt is sprinkled on an ice cube, the freezing point of water is lowered, causing the ice to melt at the interface. The meltdown creates water which, when it refreezes, binds the thread to the ice cube, allowing the ice cube to be lifted by the thread upon solidification—a process that illustrates the concept of latent heat.
