Answer:
= 9,593.1 Joules
Explanation:
Heat absorbed by water is equivalent to heat released by copper.
Heat absorbed is given by;
Q = mcΔT
where m is the mass, c is the specific capacity and ΔT is the change in temperature.
Therefore;
Since dnsity of water is 1 g/mL, and specific heat capacity is 4.18 J/g°C while the change in temperature is (75-24) = 51°C.
Heat absorbed by water = 45 g × 4.18 J/g°C × 51
= 9,593.1 Joules
Therefore, the heat released by copper is 9,593.1 Joules
