What generally happens to speed of sound when temperature increases?

A. बढ़ती है / It increases

Step 1: Identify the concept: this is a sound speed factor. Step 2: When temperature rises particles of medium have more energy and sound can travel faster. Step 3: Remember warmer air means faster sound.

Step 1: concept पहचानें: यह sound speed factor है। Step 2: Temperature बढ़ने पर medium particles की energy बढ़ती है और sound faster travel कर सकती है। Step 3: Warmer air means faster sound याद रखें।
