Two liquids

{A}

and

{B}

are at

32^{\circ} \mathrm{C}

and

24^{\circ} \mathrm{C}

. When mixed in equal masses, the temperature of mixture is found to be

28{ }^{\circ} \mathrm{C}

. Their specific heats are in the ratio

View answer and explanation

Correct option: C

1: 1

Option C (

1: 1

) is correct because when two liquids are mixed, the heat lost by one equals the heat gained by the other, and since the masses are equal, the specific heats are in the ratio 1:1.
