Question:
3 moles of an ideal gas at temperature 27C are mixed with 2 moles of an ideal gas at temperature 227C. Determine the equilibrium temperature of the mixture, assuming no loss of energy.
3 moles of an ideal gas at temperature 27C are mixed with 2 moles of an ideal gas at temperature 227C. Determine the equilibrium temperature of the mixture, assuming no loss of energy.
Show Hint
For ideal gases, equilibrium temperature depends on mole-weighted average.

Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Convert temperatures to Kelvin: T₁=300K, T₂=500K
Step 2: T=(n₁T₁+n₂T₂)/(n₁+n₂) =(3×300+2×500)/(5)=380K
Step 3: T=380-273=107C
