A ball-shaped vertical release of gas or vapor is called which term?

Explanation:
A ball-shaped vertical release is described as a cloud because the gas forms a buoyant, rounded mass that rises and expands in the air, creating a cloud-like appearance. This contrasts with a jet, which would be a narrow, continuous stream, and with a stream, which is a broader, ongoing flow. A puff is a brief, discrete burst that produces a small, short-lived shape rather than a sustained cloud. So the ball-shaped, rising formation fits the idea of a cloud, which is why that term is the best fit.
