Calculate the energy needed to raise the temperature of a 200.0 gram sample of copper by 64 degrees Celsius. (Ccu=0.386 j/g • degree C) use the equation Q = (m*c* TRIANGLE T)

Respuesta :

Answer

Q = 4940.8 J

Explanation

Given:

Mass of the copper sample, m = 200.0 grams

Change in temperature, ΔT = 64 °C

Specific heat of Cu, c = 0.386 J/g°C

What to find:

The energy needed, Q

Step-by-step solution:

Using the given equation, the energy needed can be calculated.

[tex]\begin{gathered} Q=mc\Delta T \\ \\ Q=200.0\text{ }g\times0.386\text{ }J\text{/}g°C\times64°C \\ \\ Q=4940.8\text{ }J \end{gathered}[/tex]
