Ingeniería Química

Engenharia Química é a disciplina que aplica os princípios da Química, Física e Matemática para projetar, desenvolver e operar processos industriais que transformam matérias-primas em produtos químicos, farmacêuticos, alimentos, combustíveis e outros materiais. Durante o curso, os alunos aprendem sobre termodinâmica, cinética química, operações unitárias, processos de separação, reatores químicos, entre outros temas. O engenheiro químico pode atuar em diversas áreas, como petroquímica, alimentos, cosméticos, papel e celulose, entre outras, desenvolvendo processos mais eficientes e sustentáveis para a produção de bens de consumo e insumos industriais.

Colégio Objetivo

What are the characteristics that a refrigerant fluid must have to be effective in air conditioning? I - Favorable pressure and temperature characteristics to ensure that pressures are not too high in the condenser or too low in the evaporator. II - High latent heat of evaporation value to achieve greater cooling effect. III - Critical temperature value high enough to prevent the compressor from compressing the fluid to a pressure above the critical pressure, in which case no change of state would occur in the condenser. IV - Evaporation temperature lower than ambient temperature. V - Safety against the danger of fire and explosion. VI - Chemical stability and compatibility with the materials that make up the circuit. VII - Low toxicity to avoid harm to people who handle them. VIII - Miscibility with the lubricating oil used.

What is Valeo's position regarding the replacement fluids for R12? Valeo preconizes the use of R134a as a replacement fluid for R12. The conversion process is not complex and costly. It is possible to perform a conversion by changing only the fluid. It is interesting to recover and reuse R12. a) Only I and II are true. b) Only I, II, and III are true. c) Only I and IV are true. d) Only II and III are true.
