2000g of copper initially at 25c absorbs 1000j of heat. what is final temperature

26.3°C.

Explanation:

Q = m.c.ΔT,

where, Q is the amount of heat absorbed by copper (Q = 1000 J).

m is the mass of the copper (m 2000 g).

c is the specific heat of copper (c = 0.385 J/°C.g).

ΔT is the difference between the initial and final temperature (ΔT = final T - initial T = final T - 25°C).

∵ Q = m.c.ΔT

∴ (1000 J) = (2000 g)(0.385 J/°C.g)(final T - 25°C)

∴ (final T - 25°C) = (1000 J)/(2000 g)(0.385 J/°C.g) = 1.299.

∴ final T = 25°C + 1.299 = 26.299°C ≅ 26.3°C.
