Question

(a) The diagram below shows part of the apparatus used to measure the specific heat capacity of a 1kg copper block. An immersion heater and a thermometer are inserted into holes drilled in the block.
(i) The heater operates from a d.c. supply.
Draw a diagram of the circuit which may be used to determine the power supplied by the heater.
What readings should be taken to obtain a value for the specific heat capacity of the copper?
Show how these readings should be used.
A reading of the temperature should be recorded
Every minute for 10 minutes.

Answer 1

Answer:

i)Copper

Explanation:

The specific heat of copper is 385 J/kg K. You can use this value to estimate the energy required to heat a 100 g of copper by 5 °C, i.e., Q = m x Cp x ΔT = 0.1 * 385 * 5 = 192.5 J.
