Regelation: Wire and Ice Relationship?

In summary, the conversation is about finding the relationship between force/pressure and velocity when a wire moves through ice, and the attempt at a solution includes using various formulas and incorporating latent heat into the equations.

Hi, I'm not sure if this is in the right place, so sorry if it isn't.
So basically, I need to figure out a hypothesis to find out the relationship between force (or pressure) and velocity when a wire moves through ice. I am having difficultly finding the right formula(s) to find the expected relationship.
If I wasn't clear enough, I am planning to hang masses to both sides of a wire, have the wire pass through the ice, and for the ice to refreeze again. I will be calculating the velocity of the "wire" as it passes through the ice when I change the masses.

Homework Equations


What I thought of using were several formulas and combine them together. I also did some research and here is what I got:
Work = Change in energy = Force * Distance
Pressure = Force/Area
PV=nRT
Q=mL (Latent heat)
Q= Work + U (internal energy change)

The Attempt at a Solution


Here is one of my attempts, I'm not sure if it's even valid:
P = Force / Area = W/V (Energy(work) / Volume)
P = (1/2mv^2) / Volume
F/A = (1/2mv^2) / Volume
Therefore, as the mass increases by "x", the velocity increases by "x^2".
Is this a valid response? Would it work? Also, is there any way that I can input latent heat into the formulas?

Thanks in advance!

Yes, your attempt is valid. To include latent heat into the formulas, you can use the equation Q=mL, where m is the mass of the ice and L is the latent heat of fusion of the ice. Then, you can substitute this into the equation Q=Work+U (internal energy change) to get the relationship between force, velocity and latent heat.
 

FAQ: Regelation: Wire and Ice Relationship?

What is regelation?

Regelation is the process in which ice melts under pressure and refreezes when the pressure is released.

What is the relationship between wire and ice in regelation?

In regelation, a wire can cut through ice when a load is applied due to the pressure melting the ice under the wire. This is because the melting point of ice decreases with pressure.

How does the thickness of the wire affect regelation?

The thicker the wire, the more pressure it can apply to the ice, resulting in a larger area of melted ice and a deeper cut. However, if the wire is too thick, it may not be able to cut through the ice at all.

What factors can affect the rate of regelation?

The rate of regelation can be affected by the temperature, pressure, and surface area of the ice. In general, higher temperatures and pressures result in faster rates of regelation. A larger surface area of ice in contact with the wire can also increase the rate of regelation.

What are some real-life applications of regelation?

Regelation has many practical applications, such as in ice skating, where the pressure of the skates on the ice causes a thin layer of water to form, reducing friction and allowing for smoother movement. It is also used in processes such as wire cutting and ice sculpture carving.
