A piece of copper with mass 2.5kg is heated from 30degree celcius to 80degree celcius. 50000 Joule of thermal energy is needed.What is the heat capacity of the piece of copper? What is the specific heat capacity of the piece of copper?
C=Q/(T2-T1)
c=Q/m(T2-T1)
To determine the heat capacity of the piece of copper, we need to use the formula:
Heat capacity = Thermal energy / Temperature change
1. First, we calculate the temperature change:
Temperature change = Final temperature - Initial temperature
= 80°C - 30°C
= 50°C
2. Next, we can substitute the values into the formula:
Heat capacity = 50000 J / 50°C
= 1000 J/°C
Therefore, the heat capacity of the piece of copper is 1000 J/°C.
Now, to find the specific heat capacity of the copper, we use the formula:
Specific heat capacity = Heat capacity / Mass
3. Substituting the values into the formula:
Specific heat capacity = 1000 J/°C / 2.5 kg
= 400 J/kg°C
Therefore, the specific heat capacity of the piece of copper is 400 J/kg°C.
