The temperatures of equal masses of three different liquids A, B and C are `15^@C`, `20^@C` and `30^@C`, respectively. When A and B are mixed their equilibrium temperature is `18^@C`. When B and C are mixed, it is `22^@C` .What will be the equilibrium temperature when liquids A and C are mixed

Explanation

To find the equilibrium temperature when liquids A and C are mixed, we can follow these steps:

### Step 1: Define the known temperatures and heat capacities
- Let the temperatures of the liquids be:
- \( T_A = 15^\circ C \) (for liquid A)
- \( T_B = 20^\circ C \) (for liquid B)
- \( T_C = 30^\circ C \) (for liquid C)
