Question

Answer the question​

Answer 1

Answer:

Heat lost =Heat gained <br> When 1 litre of water from A is mixed with 2 litres of water form B then the equilibrium temperature attained is

16° C

Q = mstraian >= <

tA = 2 x s x *tB - 16

(16- tA) = 2(tB- 16)

2tB+tA = 18 - (1)

<br> When 2 litres of water from A is mixed with 2 liters of water from B then the equilibrium temperture of the mixture is

41°C

2xsx(14- tA) = 2xsx(tB- 14)

14-tA = tB - 14

tB + tA = 28 - 2

2tB + 2tA = 56 - 3

3 - (1) -> tA = 8° C

tB + tA = 28

tB = 28 - tA = 28 - 8- 20 ° C
