Question 16 NECO • 2023 • PHYSICS • objective

A 150 g copper block (specific heat \(c_{Cu}=0.385\ \text{J g}^{-1}\text{°C}^{-1}\)) initially at \(200^{\circ}\text{C}\) is placed into 250 g of water at \(25^{\circ}\text{C}\) in an insulated container. After thermal equilibrium the mixture is transferred to another insulated container that contains 100 g of ice at \(0^{\circ}\text{C}\). Assuming no heat loss to the surroundings, what is the final temperature of the system (in \(^\circ\text{C}\), to one decimal place)?

A. 5.0°C

Correct Answer B. 2.2°C

C. 10.8°C

D. -3.1°C

Correct Answer

Correct Option:

2.2°C
