I probably wont get hot enough to burn paper if just placed over a cup, A good experiment that you can do is boil some water in a flask. poke a hole through a rubber stopper and place that in the flask. in the rubber stopper hole, Place a Copper tube that is in a coil making sure that some is sticking out a little bit. Place a bunsen burner under the copper coil. when steam starts to come out, place paper in the steam, it should scorch the paper but it will not catch on fire.
What else can I help you with?
You placed several crystals of iodine in a iodine chamber and covered it with a watch glass then you placed a white paper behind the chamber what will happen?
When iodine crystals are placed in an iodine chamber and covered with a watch glass, iodine vapor will sublimate and form a visible purple vapor inside the chamber. The white paper placed behind the chamber will allow the purple iodine vapor to be more easily visible against the contrast of the paper.
How can one determine the boiling point using simple distillation?
To determine the boiling point using simple distillation, one can heat a liquid mixture in a distillation apparatus and collect the vapor that is produced. The temperature at which the vapor condenses back into a liquid is the boiling point of the substance. This can be measured using a thermometer placed in the distillation apparatus.
Can boiling point of acetone be lowered if placed in a vacuum?
Yes, the boiling point of acetone can be lowered if placed in a vacuum, as reducing the pressure lowers the boiling point of a substance. This is because at lower pressure, there is less external pressure pushing down on the liquid molecules, allowing them to escape into the vapor phase more easily.
Why an increase in vapour pressure stop boiling?
An increase in pressure can stop boiling until at an increased temperature the vapor pressure equals the external pressure. That is the definition of boiling, when the vapor pressure equals the external pressure than the liquid will boil.
What happens when a cold spoon is placed near the vapour of boling water?
When a cold spoon is placed near the vapor of boiling water, the water vapor cools down and condenses into water droplets on the surface of the spoon. This happens because the cold temperature of the spoon causes the water vapor to lose energy and transform back into liquid form.
What is the relationship between boiling point and vapor pressure?
The relationship between boiling point and vapor pressure is that as vapor pressure increases, the boiling point decreases. This is because higher vapor pressure means that the liquid molecules are more likely to escape into the gas phase, leading to a lower boiling point.
What is the vapor pressure of nitrobenzene at Boiling point and at 102 degree Celsius?
The vapor pressure of nitrobenzene at its boiling point (210.9°C) is equal to the atmospheric pressure, which is 1 atm. At 102°C, the vapor pressure of nitrobenzene would be lower than 1 atm, as the boiling point is higher than 102°C.
What is Definition of superheated vapor?
superheated vapor is a vapor that has been heated above its boiling point.
What is the difference between boiling and distillation?
Boiling is the process of changing a liquid into vapor by heating it, whereas distillation is a method of separating components of a liquid mixture based on differences in boiling points. Distillation involves boiling a liquid to create vapor, then cooling and condensing the vapor to obtain purified components.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is?
The temperature at which the vapor pressure of a liquid equals the external pressure is called the boiling point. This is when the liquid changes into vapor at a constant temperature.
How is vapor pressure related to the boiling point?
Vapor pressure is related to the boiling point because the boiling point is the temperature at which the vapor pressure of a liquid equals the atmospheric pressure. When the vapor pressure of a liquid reaches the same pressure as the surrounding atmosphere, the liquid will boil and turn into a gas.
How does boiling occurs?
Boiling occurs when heat is supplied. Water is converted into vapor.
