Question

Two liquids of equal volume are thoroughly mixed. If their specific heat are C subscript 1 comma end subscript C subscript 2, temperatures theta subscript 1 comma theta subscript 2 and densities d subscript 1 comma end subscript d subscript 2 respectively. What is the final temperature of the rrixture?

  1. fraction numerator d subscript 1 c subscript 1 theta subscript 1 plus d subscript 2 c subscript 2 theta subscript 2 over denominator d subscript 1 theta subscript 1 plus d subscript 2 theta subscript 2 end fraction
  2. fraction numerator c subscript 1 theta subscript 1 plus c subscript 2 theta subscript z over denominator d subscript 1 c subscript 1 plus d subscript 2 c subscript 2 end fraction
  3. fraction numerator d subscript 1 theta subscript 1 plus d subscript 2 theta subscript 2 over denominator c subscript 1 theta subscript 1 plus c subscript 2 theta subscript 2 end fraction
  4. fraction numerator d subscript 1 c subscript 1 theta subscript 1 plus d subscript 2 c subscript 2 theta with dot on top subscript 2 over denominator d subscript 1 c subscript 1 plus d subscript 2 c subscript 2 end fraction

The correct answer is: fraction numerator d subscript 1 c subscript 1 theta subscript 1 plus d subscript 2 c subscript 2 theta with dot on top subscript 2 over denominator d subscript 1 c subscript 1 plus d subscript 2 c subscript 2 end fraction
