Sci. Doc Specific heat capacity Learning Objectives Recall the apparatus needed to determine the specific heat capacity of an object. Recall how to obtain thermal energy transfer from current, voltage and time. Calculate the specific heat capacity of an object from the gradient of a temperature vs. work done graph.

AIM: Aim V To determine the specific heat capacity of a block and to identify what material the block is made of. Sci. Doc 12 V A Stretch: To get an accurate reading, we do two things: 1. Wrap the block in an insulator. 2. Put oil in the hole with thermometer. Why? LO: I do We do You do Test
What readings will we need to take? ΔE = m x c x Δθ Measure mass of block with a balance, temperature change with a thermometer. We don’t only want to take one reading, though. We want to take multiple readings, over multiple different energy transfers & temperatures. This reduces effect of random errors. LO: I do Sci. Doc We do Calculate energy change from E = I × V × t.
