Neco Model Questions Vol1 2024 Physics Question 3
Practice objective / multiple choice question 3 from the 2024 Neco Model Questions Vol1 Physics examination.
Block A (mass \(2.0\) kg, specific heat \(0.90\) kJ·kg⁻¹·K⁻¹) is initially at \(80^{\circ}\)C. Block B (mass \(3.0\) kg, unknown specific heat \(c_{B}\) kJ·kg⁻¹·K⁻¹) is initially at \(20^{\circ}\)C. The two blocks are placed in contact in an insulated container, but during the process 5.0 kJ of heat is lost to the surroundings. When thermal equilibrium is reached the common temperature is \(50^{\circ}\)C. Determine the specific heat \(c_{B}\) of block B (in kJ·kg⁻¹·K⁻¹).
