Two effects of impurities on melting points​

Spanish

IgorLugansk [536]3 years ago

Answer:

The presence of impurities in a substance results in a lower melting point due to a process called melting point depression. Melting point depression is the reason why adding salt to frozen streets helps to melt the ice.

Melting point depression occurs due to the nature of a material's solid state. Most solids, such as ice, form as crystalline lattices of repeating ions or molecules. This lattice is held together by intermolecular forces that create a strong, stable structure. The solid must be heated to a certain temperature in order for this structure to be disrupted and for the solid to melt. However, the presence of impurities weakens the lattice, making it less stable. As a result, the compound melts at a lower temperature.

Imagina que ya has terminado tus estudios universitarios y vas a comenzar tu vida de adulto. Necesitas buscar un puesto y no sab
Katyanochek1 [597]
If I was becoming an adult and going out into the real world I would be worried and nervous. I would also feel very excited. Some doubts I may have from looking for a position for a job would be my college degree. I wouldn’t want a job that is too much work but not too easy. I would want to know, the hours I work, the days I work, the qualities I need, and the place it is located. A few emotions I may have are fear, doubt, and happiness. I would feel these because I would have doubt that I would find a job that had good pay and met my standards. I would have fear because I would be in fear of what will happen if I didn’t get the job and what I would do with my life. I would feel happy because I would be excited by what will happen next and if this would be a good career or make a new career for me in the future. These are some doubts, uncertainties, emotions, thoughts, and fears I would have in looking for a position after my university studies and going into adult life.





Spanish Version:


Si me estuviera convirtiendo en un adulto y saliera al mundo real, estaría preocupado y nervioso. También me sentiría muy emocionado. Algunas dudas que pueda tener al buscar un puesto de trabajo sería mi título universitario. No quisiera un trabajo que sea demasiado pero no demasiado fácil. Me gustaría saber, las horas que trabajo, los días que trabajo, las cualidades que necesito y el lugar donde se encuentra. Algunas emociones que puedo tener son miedo, duda y felicidad. Sentiría esto porque dudaría de que encontraría un trabajo que tuviera una buena paga y cumpliera con mis estándares. Tendría miedo porque tendría miedo de lo que sucedería si no conseguía el trabajo y lo que haría con mi vida. Me sentiría feliz porque estaría entusiasmado con lo que sucederá después y si esta sería una buena carrera o crearía una nueva carrera para mí en el futuro. Estas son algunas dudas, incertidumbres, emociones, pensamientos y temores que tendría al buscar un puesto después de mis estudios universitarios y entrar en la vida adulta.


I hope this helped, feel free to revise and/or edit this essay.
