Asked by Asteway

A lump of lead with a mass 0.5kg is dropped from a height of 20m onto a hard surface. It does not rebound but remains there for a long time.
A) what is the increase in heat
B)what is the increase in internal energy
C)what is the increase in temperature
Answered by Scott
potential energy --> kinetic energy --> heat energy

energy = m g h (in Joules)

energy / specific heat = temp change

A) and B) look like the same thing ... energy
Answered by Angesom
heat 0 and internal energy 100 b/c u=w and also at q is 0 at mekhanical work
Answered by Angesom
q is 34 ande internal energy 56

Q is 34
Answered by Bereketeab
∆Q=100 J,potential energy =mgh=>∆Q
∆U= ∆Q
∆W=0
∆T=1.56 K

does not rebound but remains there at rest for
a ∆Q, (b) ∆W and (c) ∆U for the lead during
this process?long period of time.

∆Q, (b) ∆W and (c) ∆U for the lead during
this process?
Answered by blen
What is the temperature change in the lead
immediately after the impact? [specific
heat capacity of lead = 128 kJ/kg K]
