Question

What must be the initial velocity of a lead bullet at a temperature of 25 ºC, so that the heat developed when it is brought to rest shall be just sufficient to melt it? The melting point of lead is 327.3 ºC. Specific heat capacity and latent of fusion of lead is respectively 130 J kg-1 ºC-1 and 22.4 × 103 J/kg.

Step 1

We need to find the initial velocity of a lead bullet that will generate enough heat when stopped to melt it. The bullet starts at 25 ºC and needs to reach the melting point of lead, 327.3 ºC, and then melt. Show more…
