As for vapor pressure being higher at higher temperatures, when the temperature of a liquid is raised, the added energy in the liquid gives the molecules more energy and they have greater ability to escape the liquid phase and go into the gaseous phase.n explanation of vapor pressure. Vapor pressure is constant when there is an equilibrium of water molecules moving between the liquid phase and the gaseous phase, in a closed container.
1 Melanoma is a disease in which malignant (cancer) cells form in melanocytes (cells that color the skin). 2  There are different types of cancer that start in the skin. 3  Melanoma can occur anywhere on the skin. 4  Unusual moles, exposure to sunlight, and health history can affect the risk of melanoma.here are two forms of skin cancer: melanoma and nonmelanoma.
