Measuring Temperature
... Heat depends on temperature, but also on the mass of the object, and its heat capacity. Even though Lake Ontario is at a colder temperature than your cup of coffee, it contains a lot more heat. The reason is that Lake Ontario is so much bigger (more massive) than your morning beverage. ...

Heat Transfer conduction
... Heat energy is transferred from a high heat “source” to a low heat “sink”. Heat energy will “flow” from high temperature areas to low temperature ones through one of three methods; radiation, convection or conduction. Radiation is a mode of energy transfer that does not require a medium, or substanc ...

Lecture 4: Heat transfer
... 1. CONDUCTION. Heat is transmitted by conduction when it passes from the hotter to the colder parts of the medium material without any movement of the medium itself and all intermediate parts of the material being warmed in the process. e.g. Metal rod held at one end in a fire after a period of time ...
