Does the empty flask contain more air molecules at room temperature or after it was immersed in the boiling water bath?
The empty flask contains the same number of air molecules regardless of whether it is at room temperature or immersed in a boiling water bath. However, when the flask is heated, the air molecules inside gain kinetic energy, leading to increased pressure. If the flask is sealed, some air might escape when heated, but the total number of air molecules present in the flask remains unchanged unless affected by external factors.
Why the brass need to be immersed in the boiling water before place it in the calorimeter?
The brass needs to be immersed in the boiling water for a sufficient enough time that its temperature is the same as the boiling water, 100 degrees Celsius. That will be the initial temperature of the brass. After it is quickly placed in the calorimeter which will contain much cooler water, causing the brass to cool down and the water to heat up until the point where the temperature no longer changes. At that point the temperature of the brass is the same temperature as the water in the calorimeter, which is its final temperature of the brass.
What decides how molecules behave?
The behavior of molecules is primarily determined by their chemical structure, which includes the types of atoms they contain and how they are arranged. Interactions such as bonding and forces between molecules also play a crucial role in their behavior. Factors like temperature, pressure, and the surrounding environment can also influence how molecules behave.
What is Avogadros law?
This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
What is the law that states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules?
Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. This relationship allows for the comparison of different gases under the same conditions.

Is water molecules same as water vapor?
Water molecules are the smallest units of water that contain two hydrogen atoms and one oxygen atom. Water vapor is the gaseous state of water when it evaporates at temperatures above its boiling point. Water molecules can exist as either liquid water or water vapor depending on the temperature and pressure conditions.
What is Avogadros law?
This law give the variation in volume of a gas with amount of the gas. It states that equal volumes of all gases under similar conditions of temperature and pressure contain equal number of molecules.
If the temperature of the air is said to be at absolute zero one might conclude?
the molecules contain a minimum amount of energy.
Does boiling water contain any gasses?
it contain gases cause of the minerals coming from the boiling water
The majority of biological molecules contain what atoms?
Organic molecules contain carbon.
What is the law that states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules?
Avogadro's Law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules. This relationship allows for the comparison of different gases under the same conditions.
What does s Avogadro's law say about a gas at STP?
Avogadro's law states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. Therefore, at standard temperature and pressure (STP), a given volume of gas will contain the Avogadro number of molecules, which is approximately 6.022 x 10^23.
What are molecules and their subatomic particles?
Molecules contain atoms and these atoms contain subatomic particles.
Why does a large lake at 20 degrees celsius contain more heat than a cup of boiling water?
Quantity of heat contained in a body is given by Q = M s t Here M is the mass of the body. Though the temperature is low compared to that of boiling water in a cup, the mass of lake water is comparatively very large. Hence the result
What is Avogadros Theory?
Avogadro's Theory states that equal volumes of gases at the same temperature and pressure contain the same number of molecules. This theory led to Avogadro's Law, which states that the volume of a gas is directly proportional to the number of moles of gas present.
