Question

liquid at temperature 60 degree Celsius and 20 degree Celsius respectively give masses in the ratio 3 is to 4 and their specific heat is the ratio 4 is to 5 if the equal liquids are mixed what is the resultant temperature
​

Answer 1

Answer:

liquid temperature = 60degree to 20degree

masses in the ratio = 3: 4

specific heat = 4:5

since, 60:20=4:5

p. of extreme = p. of mean

60x5=20x4

300=160

then, ans be 300:160 because temperature will come on this ratio
