Total pressure of gases is ...........to the sum of partial pressure of all gases.

Explanation

To solve the question, "Total pressure of gases is ...........to the sum of partial pressure of all gases," we can follow these steps:

### Step 1: Understand Dalton's Law of Partial Pressures
Dalton's Law states that in a mixture of non-reacting gases, the total pressure exerted by the mixture is equal to the sum of the partial pressures of each individual gas present in the mixture.

### Step 2: Define Total Pressure and Partial Pressure
- **Total Pressure (P_total)**: This is the pressure exerted by the entire gas mixture.
- **Partial Pressure (P_i)**: This is the pressure that each gas would exert if it occupied the entire volume alone at the same temperature.
