$5 kg$ of water at $1 0^{\circ} C$ is added to $10 kg$ of water at $4 0^{\circ} C$ . Neglecting heat capacity of vessel and other losses, the equilibrium temperature will be close to:

Options:

Answer:

Solution:

Heat gained = heat lost:
$5 (T_{f} - 10) = 10 (40 - T_{f})$
$15 T_{f} = 450$
$T_{f} = 3 0^{\circ} C$
