A beaker of water heated over a laboratory burner is an example of convection. The molecules at the bottom of the beaker begin to rise to the top and the cooler particles sink. This allows for the transfer of heat.

Is boiling water an example of a chemical change?
No.
What does an increase in pressure on the surface of water do to the boiling point?
It will raise the boiling point. This why, for example, car radiators have a pressure cap. This causes a rise in the boiling point of the water and it is less likely to boil.
Is an example of a physical rather then a chemical change?
Boiling water is physical change.
Water boils at 100c under ---- atmospheric pressure?
Boiling point of Water is 100 °C at 101.33 kPa = 1 Atmosphere At lower pressures the boiling point temperature reduces. For example: water boils at 3.8 °C at 0.8 kPa. At higher pressures the boiling point temperature increases. For example: water boil at 198.3 °C at 1500 kPa.
Is a campfire an example of a convection current?
no. boiling water and earth tectonic plates are good examples
An example of condution?
water boiling in a pot
Is boiling water an example of a chemical change?
No.
What are the factors that affect the boiling of liquids?
Short answer: Pressure. Long answer: Pressure changes the boiling point of a substance. The higher the pressure, the higher the boiling point, and vice versa. For example, boiling water in the mountains is easier than boiling water at sea level. Note that boiling water is not necessarily hot. You can boil water at room temperature if the pressure is low enough (For example, using a vacuum generator)
What is a following as an example of a chemical change?
boiling water

Occurs when heat is transferred into an object through motion or movement an example would be boiling water.?
Convection occurs when heat is transferred into an object through motion or movement; an example would be boiling water.

How can boiling point be used to find out if a substance is pure?
At Boiling Point all the material evaporates leaving no residue which means it is pure. But if it leaves some residue after evaporating at boiling point then it is not pure. For example : If you take an example of pure water & Saline Water then pure water will evaporate at its boiling point leaving nothing after it. But Saline water evaporates leaves salt behind it.
What is an example of a change in state?
Boiling (or freezing) water (the change to steam or ice).
Is an example of a physical rather then a chemical change?
Boiling water is physical change.
Which has the higher temperature - boiling water or ice?
boiling water
