An aluminum piece of mass 50 g initially at 300°C is dipped quickly and taken out of 1 kg of water, initially at 30° C. if the temperature of the aluminum piece immediately after being taken out of the water is found to be 160°C, what is the temperature of the water then ? (specific heat capacities of aluminum and water are 900 Jkg–1 K–1 and 4200 Jkg–1, respectively.)
(A) 165°C
(B) 45°C
(C) 31.5°C
(D) 28.5°C
