Answer is the highest temperature, so D
Higher temperatures allow for sound to move faster, since the molecules vibrate faster, sound waves can travel more quickly. The speed of sound in room temperature air is 346 meters per second. This is faster than 331 meters per second, which is the speed of sound in air at freezing temperatures.
Neat little fact: This is also why in the winter when there is snow on the ground, it seems more peaceful and quite. The snow absorbs the sound waves and the temperature makes them not travel as fast, getting more quite as they go.
Answer:
4s
Explanation:
My assumption would be 4s since 25 going into 100 would be 4? hope that helped..
Answer:
Explanation:
Given
saturated air temperature by 
Dew point temperature is given by 
Dew point is defined as the temperature after which air no longer to uphold the water vapor fuse with it and some water vapor may condense to a liquid.
air continues to rise for 1400 m
i.e. change in temperature would be 
Final temperature 
When a liquid or a gas is heated, it expands and becomes less dense, so it rises, while the cooler, denser liquid or gas sinks. (Not sure if this helps but this is what I hit)
The answer is B hope this helps
