i hsd the same problem with my 1990 520i. replace the fan clutch. your fan is not spinning fast enough. if that doesnt work replace the radiator.
It is harder to raise the temperature of water than it is to raise the temperature of a rock. It takes 1 calorie of energy to raise the temperature of 1 gram of water by 1 degree C, whereas it only takes 0.02 calorie to heat a gram of rock to that temperature.
by using a bacteriostatic agent or making conditions unfavourable for growth ie. by changing the temperature, oxygen availability, pH, nutrient media on which it is cultured.
A heater can raise the temperature of a fish tank if needed
Mass, heat capacity, the desired raise in temperature.
Water is something that will be affected if you raise the temperature. When cooking, you may need to raise the temperature of water to a boil, in order to cook food.
Yes eating spicy food can slighly raise your physical body temperature
Changing temperatures has a dramatic affect on the rate of chemical reaction. As an example for every 10 degrees you raise the environment the reaction doubles (to a certain degree)
Use the Thermostat
vasodilatation reduces body temperature.
Removing heat from the air will lower its temperature.
Depends on how high you want to raise the gram of water ;).
Shiver. The muscle action will raise the temperature.
