Porosity is a cavity-like discontinuity and occurs due to the entrapment of gases in the molten weld pool. These entrapped gases don't get a chance to escape from the molten weld pool and hence cause porosity.
<h3>Which discontinuities are caused during welding?</h3>
Weld discontinuities can be defined as "an interruption of the typical structure of a weld, such as a lack of homogeneity in the mechanical, metallurgical or physical characteristics of the weld." Porosity is considered to be the most critical discontinuity. Weld discontinuities include porosity, incomplete fusion, excessive melt.

The correct answer is grants
Explanation: An economic or social subsidy is a financial subsidy, usually granted by the government, to public or private institutions of an assistance nature. In simpler terms, it is when a public or private institution gives money to another, without the need to return this money, which is common in cases of loan or financing.
This is the encoding stage, the first stage when we receive external input for memory. This can come in the form of visual stimuli, acoustic stimuli and semantic meaning of the event, it is when the situation is going on and the brain/mind is making sense of it, if there is no such event there cannot be an experience to think about in the future. At least semantic meaning must be coupled with the stimuli as we have to ascribe a meaning to the situations we come across, and in some, if not most cases, the three forms are coupled to form the basis of memory.
The other stages are storage and retrieval. The storage stage is related to how long, how well and how a given event interacts with other events in one's life. The last stage is the retrieval stage which is when we try to remember a given stuation.
