Assuming mass does not also increase, then density decreases if volume increases. For example, let's say Mass= 100 and Volume= 50 Density would = 2 Now, lets increase the voluâ¦me. Mass would still = 100, and let's increase the volume to 75. Density would then equal 1.333... 2 is greater than 1.333....
Definition of wind tunnel. : a tunnellike passage through which air is blown at a known velocity to investigate air flow around an object (such as an airplane part or model) placed in the passage.
The Channel Tunnel, often called the Chunnel, is a railway tunnel that lies underneath the water of the English Channel and connects the island of Great Britain with mainland France. The Channel Tunnel, completed in 1994, is considered one of the most amazing engineering feats of the 20th century.he digging of the Channel Tunnel began simultaneously from the British and the French coasts, with the finished tunnel meeting in the middle. On the British side, the digging began near Shakespeare Cliff outside of Dover; the French side began near the village of Sangatte.
