Just recently, I was marking some of my students’ worksheets on Heat Energy<\/span><\/a>.<\/p>\n

I discovered that many students typically encounter difficulties in formulating\u00a0answers\u00a0for Heat Energy open-ended questions.<\/p>\n

Most students were unable to identify the keywords\/concepts and structure them coherently in their answers.<\/p>\n

    As such, I would like to use the following question as an example to discuss the answering structure<\/a>\u00a0required to answer Heat Energy open-ended questions accurately.<\/p>\n

    Background<\/span><\/h2>\n

    There are 2 containers that are packed with piping hot rice and one of the containers, container G, has holes on the lid. After some time, Rizwan\u00a0realised that:<\/p>\n

      \n
    1. The rice in container G became cooler than the rice in Container F.<\/li>\n
    2. There are water droplets formed on the inside of Container F.<\/li>\n<\/ol>\n

        Template Answer<\/span><\/h2>\n

        There are two important things to note when it comes to answering Heat Energy questions:<\/p>\n

        1) ______ (cooler substance)<\/span> gains heat from ______ (warmer substance)<\/span><\/em> or<\/strong>\u00a0<\/em><\/p>\n

        \u00a0 \u00a0\u00a0\u00a0______ (warmer substance)<\/span> loses heat to ______ (cooler substance)<\/span><\/em><\/p>\n

        2) to\u00a0\u00a0<\/strong>____________ (heat process)<\/span><\/em><\/p>\n

        An example would be: The puddle of water\u00a0gains heat from<\/span> the warmer surrounding air\u00a0to\u00a0evaporate…<\/span><\/span><\/p>\n

         <\/p>\n

        Answering Technique for Part (a)<\/span><\/h2>\n
        \n

        The water vapour in the air in the containers<\/span> gained heat from<\/strong> the hot rice<\/span> to become warmer<\/strong> and rises up. The holes on the lid of container G allows some of the warmer water vapour<\/span> to escape more easily<\/strong> into the cooler surrounding air, thus causing the rice in container G to cool faster.<\/p>\n<\/blockquote>\n
