What mass of copper will absorb 450 joules of energy when the temperature goes from 47 to 4? The specific heat of copper is 0.38 J/g
450 = mass Cu x specific heat Cu x (47-4)
Solve for mass Cu\
To find the mass of copper that will absorb 450 joules of energy, we can use the specific heat equation:
Q = m * c * ΔT
Where:
Q is the energy absorbed (450 J in this case)
m is the mass of copper in grams (which we need to find)
c is the specific heat of copper (0.38 J/g°C)
ΔT is the change in temperature in degrees Celsius (47 - 4 = 43°C in this case)
Rearranging the equation, we can solve for m:
m = Q / (c * ΔT)
Now, let's substitute the values into the equation:
m = 450 J / (0.38 J/g°C * 43°C)
m ≈ 29.64 g
Therefore, the mass of copper that will absorb 450 joules of energy when the temperature goes from 47 to 4 degrees Celsius is approximately 29.64 grams.
