Como escolher o arquivo certo
O formato deve atender ao modo como você pretende editar ou publicar a imagem. PNG e SVG aparecem entre os formatos indicados em resultados do Pixabay; a busca da Pngtree também descreve formatos como EPS, AI e PSD. A disponibilidade depende do item.
- Formato: confirme se o arquivo é rasterizado, como PNG, ou vetorial, como SVG, EPS ou AI. Verifique também se o PSD escolhido contém as camadas de que você precisa.
- Fundo: se a imagem for usada sobre outra cor ou composição, procure uma indicação de transparência e confirme o resultado no arquivo baixado.
- Estilo e forma: escolha uma ilustração que represente claramente o objeto pretendido. Um tubo de ensaio é comprido e estreito, aberto no topo e arredondado na base, segundo José Ricardo Pinto, em artigo da Revista de Ciência Elementar da Universidade do Porto.
- Licença: verifique as permissões para seu uso específico e se há exigência de atribuição. A palavra “gratuito” não esclarece, sozinha, as condições de reutilização.
O que representa um tubo de ensaio
Além de ajudar a avaliar se a ilustração corresponde ao que você procura, a forma do objeto tem uma função: tubos de ensaio são usados em reações com pequenas quantidades de reagentes. Pinto explica que o formato longo e estreito favorece a condensação de vapores durante o aquecimento de líquidos ou uma reação química. Leia o artigo da Revista de Ciência Elementar.
