to provide ideal conditions for enzymes to carry out metabolic reactions etc etc
All metals expand when heated and contract when cooled. It is important, therefore, that the standard metre is kept at some constant temperature. That constant temperature could be any temperature but the triple point of water is a convenient benchmark.
Temperature and amount (number of moles) is kept constant.
furnace, fridge
not sure
Temperature and the amount of gas (moles) must be kept constant for Boyle's law to hold true. This means the pressure and volume of a gas are inversely proportional provided the temperature and amount of gas remain constant.
This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
Our Body Condition are constantly changing. Any drastic change in the blood and thesurrounding tissue fluid will effect chemical reactions in the cells and will harm the body. For Example the temperature of the body must be kept constant because enzymes in the body work within a certain range of temperature and any change in the temperature may result in an inactivation of the enzymes and this will prevent an important reaction from taking place.
To keep urine at body temperature, you can use hand warmers or keep the container close to your body for warmth. It's important to make sure the urine is not too hot as it should be close to body temperature but not higher. Make sure to check the temperature before using it for any purpose that requires it to be at body temperature.
So as not to upset/shock the body temperature of the person who is on dialysis.
Body temperature remains relatively constant regardless of external weather conditions. However, extreme cold or hot weather can affect how the body maintains its temperature through mechanisms like shivering or sweating to keep it within a normal range.
The factor that is kept constant in an experiment is called the controlled variable. It is important to keep this variable constant to accurately measure the effect of the independent variable on the dependent variable.
