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 Tumors. A malignant tumor is a group of diseased cells defined by one of three characteristics: uncontrolled growth, invasion and damage of healthy cells, or metastasizing (spreading) to other organs of the body.They differ from benign tumors, which do not spread or affect other areas of the body. malignant tumor is a group of diseased cells defined by one of three characteristics: uncontrolled growth, invasion and damage of healthy cells, or metastasizing (spreading) to other organs of the body.
Well, a malignant tumor is a tumor that is invasive, meaning it can invade the surrounding tissues. Malignant tumors contain cells that are cancerous, growing out of control and capable of metastasizing. Metastasize simply means that the cells of the tumor are able to leave the original tumor and travel to other parts of the body. In cancerous tumors or malignant tumors, the cells have lost the ability to stop growing. In other words, they have gone rogue and will not stop dividing. To better explain, nearly every cell in the body is able to grow and divide to make new cells, to a certain extent.
