WebWe can find the gradient of the straight part of the graph. We know that the change in energy = mass x specific heat capacity x change in temperature. Since the gradient of the graph is (change in temperature / energy transferred) the specific heat capacity is "1 / (gradient x mass of the block) WebJan 24, 2024 · AQA GCSE (9–1) Biology Required Practicals Lab Book 978-0-00-829161-7 AQA GCSE (9–1) Chemistry Required Practicals Lab Book 978-0-00-829162-4 291648_GCSE Combined Science Lab Book cover ... owner of gotham museum of art
