Specific heat capacity from gradient. Apparatus for heating water and measuring energy supplied.
Specific heat capacity from gradient Dependent variable = Temperature, T. Variables. . Independent variable = Time, t. This experiment aims to determine the specific heat capacity of a solid and of water by measuring the energy required to increase the temperature of a known amount by one degree. The equation Q=mcΔT is used and rearranged to get c=Q/mΔT. Control You can use the equation for energy required to change temperature to find what your gradient represents: c is the specific heat capacity of aluminium. Nov 6, 2012 · In summary, the conversation discusses the process of finding the specific heat capacity of water using an experiment with an electric kettle. If we write the specific heat capacity equation in the form, then we notice that the gradient of our line of best fit is just, so we can calculate the specific heat capacity from the graph using, For our example data the gradient of the line is gradient = 38/33000, and the mass of the block is 1kg, so the specific heat capacity of the material is, A practical for specific heat capacity involves measuring the temperature changes of different materials when they are heated . This means you can find the specific heat capacity by dividing your value of gradient by the measured mass of the aluminium block. An investigation involves linking the decrease of one store of one energy store to the increase in thermal energy store. Since the mass is 1kg, the inverse of the gradient = specific heat capacity of the block. Apparatus for heating water and measuring energy supplied.

Nov 2, 2024 · Core practical 11: investigating specific heat capacity Aims of the experiment. Dec 4, 2024 · Particle Model States of Matter & Thermal Capacity Core Practical: Investigating Specific Heat Capacity. The gradient of the graph is equal to the specific heat capacity of the water, assuming a perfectly efficient immersion heater. Specific heat capacity is the gradient divided by the mass of the block. vby gqvdhj slqklbr bofjz gvirn iwgg hnoc lobiv tfgcp dasr
