Temperature is a measure of the average kinetic energy of the atoms or molecules in the system. The water molecules in a cup of hot coffee have a higher average kinetic energy than the water molecules in a cup of iced tea, which also means they are moving at a higher velocity.The specific heat capacity is how much energy is needed to increase the temperature of one gram of a substance by 1°C or 1K.
In Science, increasing the surface area of a gas increases its collision rate and is one evolutionary strategy that has maximized gas diffusion by catalysing the rate of gaseous reaction.
