What change in the water level occurs when you hold Erlenmeyer flask over a candle in a pan of water?
When you hold an Erlenmeyer flask over a candle in a pan of water, the water inside the flask heats up and expands, causing the water level in the flask to rise. This is due to the expansion of the water molecules as they gain thermal energy from the heat source.
What happens when a flask is heated up with a burner after ten minutes?
If a flask is heated up with a burner for ten minutes, the temperature of the liquid inside the flask will increase. This increase in temperature can lead to changes in the properties of the liquid, such as expansion, evaporation, or chemical reactions, depending on the type of liquid and the temperature reached. It is important to monitor the temperature carefully to prevent overheating or boiling over.
What is the basic setup required for a simple distillation process?
The basic setup for a simple distillation process includes a distillation flask, a distillation column, a condenser, a receiving flask, and a heat source. The mixture to be separated is heated in the distillation flask, and the vapors rise through the column where they condense in the condenser and are collected in the receiving flask.
What is the function of the silvered surface in a vacuum flask?
The silvered surface in a vacuum flask helps to reflect heat back into the container, reducing heat transfer by radiation. This helps to maintain the temperature of the contents inside the flask by minimizing heat loss or gain.
A sample of nitrogen gas is stored in a 500.0ml flask at 108kpa and 10.0c the gas is transferred to a 750.0ml flask at 21.0c what is the pressure of nitrogen in the second flask?
To find the pressure of the nitrogen gas in the second flask, you can use the combined gas law equation: P1V1/T1 = P2V2/T2, where P1, V1, and T1 are the initial pressure, volume, and temperature, and P2, V2, and T2 are the final pressure, volume, and temperature. Plug in the given values to find the final pressure of nitrogen in the second flask.

Why the temperature in a flask tha contains dry peas doesn't change at the room temperature?
The temperature in the flask remains constant because the peas act as insulation, limiting heat transfer between the inside and outside of the flask. This insulation effect prevents the temperature from changing easily.
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.
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
Temperature related to saponification value?
Heat the flask on a steam bath.
What happens when a flask is heated up with a burner after ten minutes?
If a flask is heated up with a burner for ten minutes, the temperature of the liquid inside the flask will increase.

It is important to monitor the temperature carefully to prevent overheating or boiling over.
Why do the inner surface of thermos flask kept shiny?
The shiny inner surface of a thermos flask helps to reflect heat back into the flask, reducing heat transfer to or from the contents. This helps to maintain the temperature of the liquid inside the flask for a longer period of time.
What is the role of the porcelain chips in the flask?
to distribution the temperature in round bottom flask
What is the basic setup required for a simple distillation process?

The mixture to be separated is heated in the distillation flask, and the vapors rise through the column where they condense in the condenser and are collected in the receiving flask.
Does the temperature rise or drop in the exosphere?
rise
How would you explain the temperature rise in the water?
The temperature rise because of the gangnam dance
