Gce Model Questions Vol1 2024 Physics Question 31
Practice objective / multiple choice question 31 from the 2024 Gce Model Questions Vol1 Physics examination.
A solid copper cylinder has radius \(5\ \text{cm}\) and height \(10\ \text{cm}\). The density of copper is \(8.96\times10^{3}\ \text{kg m}^{-3}\). The cylinder is initially at \(20^{\circ}\text{C}\) and is heated by a \(700\ \text{W}\) electric heater for \(5\) minutes. During heating, \(20\%\) of the electrical energy is lost to the surroundings. Assuming all the remaining energy raises the temperature of the copper, calculate the specific heat capacity of copper in \(\text{J kg}^{-1}\text{K}^{-1}\).
