The final temperature is 44°C.
Explanation:
- Mass of water = 2 kg
- Initial temperature = 80° C
- Mass of water = 3 Kg
- Temperature of second water body = 20°
Solution:
The formula is given:
m2 ( T - 20 ) = m1 ( 80 - T )
3 (T - 20) = 2 (80 - T)
3T - 60 = 160 - 2T
3T + 2T = 160 + 60
5 T = 220
T = 220 / 5
T = 44° C
Thus the final temperature is 44°C.

Answer:
- The Final temperature of the mixture (T) is 44°C
Given:
- Mass of Water (M₁) = 2 Kg.
- Temperature of Water (T₁) = 80°C
- Mass of Water (M₂) = 3 Kg.
- Temperature of Water (T₂) = 20°C
Explanation:
As question states that there is no heat loss.
Therefore, we can write,
Substituting the Values,
Specific heat will be same as In both conditions Water is Added.
Simplifying,
∴ The Final temperature of the mixture (T) is 44°C.
