An good example would be using a Bunsen burner to heat water in a tin container. The flame initially heats the tin can by radiating heat. Conduction then transfers heat from the tin can to the water. The convection process causes the hot water to then climb to the top.
<h3>What is Bunsen Burner?</h3>
A laboratory piece of equipment known as a Bunsen burner, which bears Robert Bunsen's name, produces a single open gas flame and is used for heating, sterilization, and combustion. Natural gas, liquefied petroleum gas, such as propane, butane, or a combination, are all acceptable choices for the gas.
<h3>What three types of flames can you get from a Bunsen burner?</h3><h3>Bunsen burner flames come in three primary categories:</h3>
- Because it is simple to notice in a well-lit space, a yellow flame is also referred to as a safety flame.
- Flaming Blue. A burner's specific flame can reach temperatures of 500 degrees.
- Blue Flame in Flames The roaring blue flame setting on a Bunsen burner produces the hottest flames.

Answer:
Answer to #1, is D.
Explanation:
The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. This is also, a theory with the ring of fire.
The concept required to solve this problem is that related to the Isobaric process. Isobaric process is understood as the process in which changes occur at constant pressure. From the first law of thermodynamics this can be expressed as,
Here,
P = Pressure
dV = Differential of Volume
As the Pressure is constant we have,
Replacing
Therefore the correct answer is A.
Magnets don’t need to touch each other in order to be magnetic because all objects have an attraction however, the closer the magnets get, the more magnetic it is.
Answer:
v2 = 12m/s
Explanation:
To find the velocity of water in the lower tube you use the following formula:
(1)
v1: velocity in the first tube
v2: velocity in the second tube
A1: area of the first tube
A2: area of the second tube
From the expression (1) you can obtain the velocity v2, that is the velocity of water in the second tube:
you replace the values of the parameter in order to calculate v2:
hence, the velocity of the water is 12m/s
