One way to demonstrate the presence of air is to create a vacuum inside a closed container and observe that a vacuum pump is required to remove the air. Another method is to perform the candle jar experiment, where a lit candle placed in a jar is extinguished due to the depletion of oxygen, showing the presence of air. Alternatively, using a balloon over the mouth of a bottle containing baking soda and vinegar can show the production of gas (carbon dioxide) as a result of the chemical reaction, indicating air's presence.

What are necessary to ensure no air trapped within the device at the beginning of the experiment?
To ensure no air is trapped within the device at the beginning of the experiment, it is necessary to properly prime the system by filling it with the appropriate liquid or gas before starting the experiment. This can help displace any pockets of air that may be present. Additionally, ensuring all connections and seals are tight can help prevent air from being trapped within the device.
How will you show that water vapour are present in air explain with help of diagram?
One way to show that water vapor is present in the air is by using a hygrometer, a device that measures humidity. The hygrometer will display the percentage of water vapor present in the air. You can also demonstrate this concept using a diagram by showing arrows representing water molecules in the air and indicating the percentage of water vapor present in relation to the total air molecules present.
Give an experiment to show that air a bad conductor of heat?
You can conduct an experiment by heating a metal rod at one end and touching it to a balloon filled with air. The balloon will not pop immediately because air is a poor conductor of heat, so the heat does not transfer quickly enough to cause the balloon to burst.
How do you make an experiment to show that air occupies space?
To demonstrate that air occupies space, you can use a simple experiment by inflating a balloon and then placing it in a container filled with water. As the balloon is submerged into the water, you will notice that it displaces water, showing that the air inside the balloon is taking up space.
How can you say that water vapour are present in air give an activity to explain it?
One way to show that water vapor is present in the air is to cool the air. If the air temperature drops below its dew point, water vapor in the air will condense into tiny droplets, forming visible fog or mist. This process demonstrates that water vapor is a component of the air.

How bicarbonate indicator show present of oxygen or not?
if oxygen present the colour of bicarbonate indicator will change to brown like in my experiment,i think it's not fully successful but not dissapoint me.
Why to destarch a plant?
a leaf (plant) should be destarched before photosynthesis investigations because the starch already present in the plant may mislead the result . hence if a destarched plant is used for the experiment then the amount of starch present at the time of the experiment will be nil and affter the experiment is compleded the amount of starch present in the leaves woul give the rate of photodynthesis as starch id prepared during photosynthesis

How can you show that air is necessary for combustion?
One way to show that air is necessary for combustion is by conducting an experiment where a fire is placed in a sealed container. As the fire consumes the available oxygen within the container, it will eventually extinguish due to the lack of oxygen needed for combustion. This demonstrates the necessity of air in supporting combustion.
An experiment to show that ice melt faster in water that air?
get 2 icecubes that are similar sizes and put one in room temperature water and the other exposed to air.
When was An Experiment on a Bird in the Air Pump created?
An Experiment on a Bird in the Air Pump was created in 1768.

How will you show by experiment that air contains water vapour?
One way to show that air contains water vapor is to cool the air, causing the water vapor to condense into a visible cloud or mist. This can be demonstrated by breathing onto a cold surface or by observing condensation forming on a cold glass. Another approach is to use a hygrometer to measure the relative humidity of the air, which indicates the amount of water vapor present.

What is the negative control in the lactose experiment?
The negative control in the lactose experiment would be a sample that does not contain lactose or the enzyme needed to break down lactose. This control is used to show what would happen if no lactose were present for the enzyme to act on.
