Saturated vapour pressure and boiling point. A liquid boils when its saturated vapour pressure becomes equal to the external pressure on the liquid. When that happens, it enables bubbles of vapour to form throughout the liquid-those are the bubbles you see when a liquid boils. liquid boils when its saturated vapour pressure becomes equal to the external pressure on the liquid.

Malignant cancer is any form of cancer or growth that can spread to other parts of the body in a process called metastasis. It is compared to benign growths or cancers that do not easily spread to other parts of the body and may be much easier to treat.umors can grow in areas of the body such as the brain and be malignant or benign.
