A 0.0500-kg lead bullet of volume 5.00 à 10-6 m3 at 20.0 °C hits ablock that is made of an ideal thermal insulator and comes to restat its center. At that time, the temperature of the bullet is 327°C. Use the following information for lead:
coefficient of linear expansion: a = 2.0 à 10-5/C°
specific heat capacity: c = 128 J/(kg ⢠C°)
latent heat of fusion: Lf = 23 200 J/kg
melting point: T melt = 327 °C
How much heat was needed to raise the bullet to its finaltemperature?
A) 963 J B) 1930 J C) 3640 J D) 3880 J E) 4440 J
