What else can I help you with?
Flask A contains 2 liters of ch4 g and flask B contains 2 liters of o2 g each gas sample has the same?
The gas particles in both flask A and B will have the same average kinetic energy at the same temperature. This is because temperature is a measure of the average kinetic energy of the gas particles, and since they are at the same temperature, their average kinetic energies will be equal.
What happens when a thermo flask contains some ice cubes?
The ice cubes will help to keep the contents of the thermos flask colder for a longer period of time. The thermos flask's insulation will prevent heat transfer from the surroundings, helping to maintain the temperature of the ice cubes and the contents of the flask. Over time, the ice cubes will melt and help to cool the contents of the flask.
Does the flask contain the same more or fewer gas molecules compared to before it was heated?
The flask likely contains the same number of gas molecules before and after heating, as heating typically does not change the number of molecules present. However, the molecules may gain energy and move faster with increased temperature.
What probably happened to the temperature of the air the flask and the wood during the reaction?
During a chemical reaction, the temperature of the air surrounding the flask and the wood likely increased. This is because chemical reactions often release energy in the form of heat, known as an exothermic reaction. As the reactants in the flask and the wood underwent a chemical change, the energy released would have heated up the immediate surroundings.
What is the role of the porcelain chips in the flask?
to distribution the temperature in round bottom flask

What if three identical flasks contain three different gases at stp flask a contains ch4 flask b contains CO2 flask c contains n2 which flask contains the largest number of molecules?
Flask A containing CH4 would have the largest number of molecules because all the gases are at STP (Standard Temperature and Pressure), so they will occupy the same volume. Since CH4 has the lowest molar mass among the gases given, it will have the highest number of molecules in the flask.
Why did the temperature rise in flask a?
The temperature in flask A rose because heat was transferred from the surroundings to the contents of the flask, increasing the kinetic energy of the molecules and causing their temperature to increase.

Substance that contains the vacuum in a vacuum flask?
Glass
If A flask contains 440 mol of liquid bromine Determine the number of bromine molecules in the flask?
There are approximately 2.65 × 10^26 bromine molecules in the flask. This is calculated by multiplying Avogadro's number (6.022 × 10^23 molecules/mol) by the number of moles of bromine present in the flask (440 mol).

How do you get an egg out of a flask?
you heat the bottom of the flask. as temperature goes up, the volume will go down and push the egg out.
Why is the inside of a vacuum flask shiny?
The inside of a vacuum flask is shiny because of the reflective metal coating, usually made of stainless steel. This shiny surface helps to reflect heat radiation, which helps to maintain the temperature of the liquid inside the flask.
What Vacuum flask keeps liquid at same temperature?
There is no way to permanently store heat. The most you can expect, from a high-quality vacuum flask, is to keep the liquid cold, or hot, for a fairly long time. But gradually, some heat will seep in, or out, until the temperature in the vacuum flask will be equal to the temperature of the surroundings.
How does a vacuum flask reduce heat loss from a hot liquid inside?
Due to open space isolating the flask from external temperature
