Document Summary
Every 10m in water depth increases pressure by 1kg/cm2. Specific heat- heat required to raise the temp of 1 gram of a substance by 1c (unit for specific heat: calories/gram/c. Heat is energy produced by the random vibrations of atoms or molecules. Temperature is an objects response to an input or removal of heat. Heat capacity- a measure of the heat required to raise the temp of 1gram of a substance by 1c. Water has a very high heat capacity (which means its resists changing temp when heat is added or removed). Waters temperature affects its density (density drops after water reaches 3. 98c) Sensible heat- heat that causes a change in an objects temperature. (measurable by temp change) Latent heat- the heat that is required to change substance"s physical states (solid, liquid, gas) (not measurable by temp change) Ex: q(sensible heat)= c(specific heat) * m(mass) * t(change in temp) Q(latent heat) = l(specific latent heat) * m(mass)
