What happens when the end of a metal rod is heated?
When one end of a metal rod is heated, the kinetic energy of the molecules at that end increases. Thus the kinetic energy of the neighbouring molecules increases hence their amplitude of vibration increases and during the collision the energy transfers to the next molecule. Thus heat transfer takes place by conduction.
When one end of a metal rod is heated the other end of the road gets heated?
The other end of metal rod gets heated due to conduction. This is because conduction takes place due to vibration of atoms in a substance and convection takes place due to heat transfer with actual movement of particles. It is due to conduction.
When one end of a metal rod is?
One end of a metal rod of length 1.0 m and area of cross section 100 cm^(2) is maintained at . 100^(@)C. If the other end of the rod is maintained at 0^(@)C , the quantity of heat transmitted through the rod per minute is (Coefficient of thermal conductivity of material of rod =100 W//m-K)
Why are you not able to hold a metal rod from one end while the other end is being heated?
This is because the molecules in metals vibrate and hit the nearby molecules to transfer the heat energy, rather than moving from one place to the other.
What happens when you put a metal rod in hot water?
These faster moving water molecules transfer energy to the metal rod where they are touching. The energy from the hot water makes the molecules of the metal rod move faster, which we can feel as the rod heating up. Eventually the molecules lose their heat energy to the air and the rod cools down again.
When a metal rod attains the same temperature?
When a metal rod attains same temperature through out its length, then its conductivity is (1) zero.
Is the end of metal rod is heated then the flow of heat does not depend on?
Clearly the rate of heat flow is independent of mass of rod.
When you put a metal rod into a fire soon you will feel the rod becoming what?
Explanation: As we know that metal rod is a good conductor of heat. So, when we put one end of a metal rod on flame the heat easily passes to the other end of the rod. That is why we feel hot at another end.
When you put a metal rod into a fire?
When one end of a metal rod is put into a fire, the energy from the flame makes the ions in the rod vibrate faster. Since the ions in the solid metal are close together, this increased vibration means that they collide with neighbouring ions more frequently.
When you heat a metal rod it will expand permanently?
When metal rod is heated it expands because as the temperature increases the atoms starts to vibrate. This vibration of atoms leads to the separation of atoms inside the metals. This separation is not enough to break the bonds between atoms but make them slightly apart. This is known as thermal expansion.
