A 6.50-g sample of copper metal at 25.0°C is heated by the addition of 84.0 J of energy.The final temperature of the copper is ________°C.The specific heat capacity of copper is

Question

Quizplus · Accepted Answer

The amount of heat energy required to raise the temperature of copper can be calculated using the formula:

q = m * c * ΔT

where q is the heat energy, m is the mass of copper, c is the specific heat capacity of copper, and ΔT is the change in temperature.

Rearranging the formula to solve for ΔT:

ΔT = q / (m * c)

Plugging in the given values:

ΔT = 84.0 J / (6.50 g * 11.0 J/(g°C))
ΔT = 1.24°C

Since the starting temperature is 25.0°C, the final temperature is:

final temperature = 25.0°C + 1.24°C
final temperature = 26.24°C

Rounding to the nearest tenth:

final temperature = 26.2°C

Therefore, the best choice is D) 59.0.
