10 gm of steam at 100 degree celcius is mixed with 50 gm of ice at 0 degree celcius then final temperature is....???
Answers
The final temperature is 40°C.
Explanation:
10 gm steam to 10 gm water at 1000 °C
Heat released = 10 × 540 = 5400 cal
= 10 × 540 = 5400 cal
50 gm Ice to 50 gm water at 0°C
Heat absorbed = 50 × 80 = 4000 cal
- Let the final temperature be t°C.
So 10 gm water at 1000 C to 10 gm water at t°C
Heat released
= 10 × 1 × (100−t) = 1000^−10 t cal
50 gm water at 00 C to 50 gm water at t0 C
- Heat released
= 50 × 1 × (t−0) = 50t cal = 50 × 1 × t-0 = 50 t cal
- Now
5400 + 1000 − 10t = 4000 + 50t
⇒ 60 x t = 2400
⇒t = 40°C
Thus the final temperature is 40°C.

Answer:
16.66° c
Explanation:
The given datas are
Steam
mass (m₁) = 10 g
Temperature (T₁) = 100° C
ICE
mass (m₂) = 50 g
Temperature ( T₂) = 0° C
Let the final temperature be T₀
We know that , Q = m c dt ( c = specific heat constant )
Heat lost by a body = heat gained by another body
m₁ c ( T₁ - T₀) = m₂ c ( T₀ - T₂)
10 * ( 100 - T₀) = 50 ( T₀ - 0⁰)
100⁰ - T₀ = 5T₀
T₀ = 16.66⁰ C
So the final temperature is 16.66° c
