The presence of a catalyst affect the enthalpy change of a reaction is that catalysts do not alter the enthalpy change of a reaction. Catalysts only change the activation energy which starts the reaction.
skin has goosebumps on it that keep the temprature of are body constant .moreover skin release sweat that produces cooling affect and maintains body temprature.
Enthalpy- positive Entropy- decreasing Free energy- negative
The force constant is unaffected; It is a constant.
Fast cooling=small crystals Slow cooling=big crystals
How do the heating and cooling differences between land and water affect us? ...
They can. They produce an increased albedo affect and cause cooling.
Cooling treatments slow chemical reactions within the body
constant flowing affect erosion
color only affects the cooling time of objects if there is light
The higher the temperature the faster the chocolate will melt.
it kills it
