I think this is done to allow even distribution of temperature in all the regions of the calorimeter. That is to make sure that there are no hot or cold spots and also ensure that the measured temperature is the actual average temperature when the readings are taken by a thermometer.
Answer: The boiling point of water is an absolute constant
Explanation:
The boiling point of a compound is NOT an absolute constant. This is because at certain conditions such as a change in altitude, the boiling point of a compound changes.
As temperature increases, evaporation increases and vapour pressure increases. Compounds boils when vapour pressure equal to the atmospheric pressure.
At higher altitudes, atmospheric pressure is decreses.
When atmospheric pressure is decresed, the vapour pressure of the compound is lowered to reach boiling point. Therefore, the temperature needed for vapour pressure to equal atmospheric pressure is lower. The boiling point is lower at higher altitude.
Hence boiling point depends on atmospheric pressure
FALSE there are many ways to conduct scientific investigations
Answer:
While there is an increase in the use of reusable cloth bags, plastic shopping bags have two big advantages: Plastic bags are more durable than paper bags. They are less prone to tearing, easier to carry, and are far more useful in bad weather
