Which property of gas helps us in detecting Jeakage of cooking gas (LPG).

Explanation

**Step-by-Step Solution:**

1. **Understanding LPG**: LPG stands for Liquefied Petroleum Gas, which primarily consists of propane and butane. These gases are used commonly for cooking.

2. **Detection of Leakage**: To detect the leakage of LPG, a chemical called ethyl mercaptan is added to it before it leaves the storage terminals. This chemical has a strong and distinctive smell.

3. **Role of Ethyl Mercaptan**: When there is a leak in the LPG, the ethyl mercaptan escapes along with the gas, and its strong odor is what helps us detect the leakage.
