A bucket containing 8kg of water at 25c.2kg of water at 80c poured into it. Neglecting the heat energy absorbed by bucket, calculate the final temperature of water |
|
Answer» principle of calorimetry,Heat GAINED by cold water = Heat lost by hot waterLet the final temperatures be x8*4200*(X - 25) = 2*4200*(80 - x)or, 8x - 200 = 160 - 2xor, 10x = 360or, x = 36Final TEMPERATURE of the MIXTURE = 36 degC |
