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.
Carcinoid Tumor. Carcinoid tumor is a rare type of tumor that grows slowly. Malignant tumors are cancers that often continue to grow and may spread to other areas of the body. Benign (noncancerous) tumors tend to grow more slowly and donât spread. Carcinoid tumors are somewhere between malignant and benign tumors.ypes of carcinoid tumors include: Slow-growing tumors. These tumors are the most common type. They usually remain small, under about an inch wide, and donât grow quickly or spread to other areas of the body. Faster-growing tumors. These tumors may grow more rapidly, grow larger, and spread.
