what is the specific heat of copper if the temperature of a 100g sample of copper is increased by 23C when 886J of heat is added ?
q = mass Cu x specific heat Cu x delta T.
q = 886 J.
To find the specific heat of copper, we can use the formula:
q = m * c * ΔT
Where:
q = heat energy (in joules)
m = mass (in grams)
c = specific heat capacity
ΔT = change in temperature (in degrees Celsius)
In this case, we are given:
q = 886 J
m = 100 g
ΔT = 23 °C
We can rearrange the formula to solve for c:
c = q / (m * ΔT)
c = 886 J / (100 g * 23 °C)
To calculate the specific heat of copper, simply divide 886 J by the product of 100 g and 23 °C:
c = 886 J / (100 g * 23 °C)
c ≈ 0.384 J/g°C
Therefore, the specific heat of copper is approximately 0.384 J/g°C.
