Answer:
Explanation:
Given:
temperature at the hotter end,
temperature at the cooler end,
length of rod through which the heat travels,
cross-sectional area of rod,
mass of ice melted at zero degree Celsius,
time taken for the melting of ice,
thermal conductivity k=?
By Fourier's Law of conduction we have:
......................................(1)
where:
=rate of heat transfer
dT= temperature difference across the length dx
Now, we need the total heat transfer according to the condition:
we know the latent heat of fusion of ice,
Now the heat rate:
Now using eq,(1)
The material that the cylinder is made from is Butyl Rubber.
<h3>What is Young's modulus?</h3>
Young's modulus, or the modulus of elasticity in tension or compression, is a mechanical property that measures the tensile or compressive strength of a solid material when a force is applied to it.
<h3>Area of the cylinder</h3>A = πr²
Where;
- e is extension
When 5 kg mass is applied, the extension = 10 cm - 9.61 cm = 0.39 cm = 0.0039 m.
When the mass is 50 kg,
extension = 10 cm - 7.73 cm = 2.27 cm = 0.0227 m
The Young's modulus is between 0.001 GPa to 0.002 GPa
Thus, the material that the cylinder is made from is Butyl Rubber.
