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.
A potentially life-threatening mass of cancerous cells. Malignant tumors are ambitious. Unlike benign tumors that generally stay put, malignant tumors have two goals in life: â¦to survive and to conquer new territory. So, if you have a malignant tumor in your colon, it's going to try to work its way through your colon. If successful, it will see where else it can go. This is called metastasizing. In general, malignant tumors grow faster than benign tumors and are more likely to cause health problems.
