Question
Consider some copper beads that are initially at
T, = 200 °C, with each bead having a mass of m,
= 1.00 g. Consider also a bucket of water (m, =
1.00 kg) that is initially at T2 = 20.0°C. Suppose
you want to raise the temperature of the bucket of
water to T, i.e., by dropping N number of copper
1
beads into the water.
(Note: Subscript 1 represents copper beads,
subscript 2 represents water. Neglecting any
energy transfer to or from the container.)
