The temperature of a copper sample weighing 250 g rose from 30 degrees Celsius to 70 degrees Celsius. How much heat did the sample receive?
Given:
m = 250 g = 0.25 kg;
t1 = 30 C;
t2 = 70 C;
c = 400 J / kg * c – specific heat capacity of copper;
Q -?
Solution:
Q = m * c * (t2 – t1);
Q = 0.25 * 400 * (70 – 30) = 4000 J.
