Thermal Conductivity
... Consider a conductive bar initially a room temperature. If one end of the bar is place on a fire, the temperature at that end will begin to rise making the molecules vibrate with larger amplitude. These molecules will cause their neighbors to vibrate with larger amplitude as well and so on until thi ...

... What that common temperature is depends on the amount of heat (i.e. thermal energy) in the system. Some of the factors that come into play are: How much (mass of) food there is. How much (mass of) your mouth is involved (see below). The initial temperature of the food. The "specific heat" of both th ...

Determination of Heat of Combustion of Liquid
... The constant volume constraint means that pressure is not constant and neither is temperature making this an adiabatic process. The other type of heat of combustion is net heat of combustion. This is similar to gross heat of combustion but occurs at constant pressure rather than constant volume. The ...
