How much heat is necessary to raise the temperature of a 15.0g metal from 15 degrees celsius to 25.0 degrees celsius?
q = mass metal x specific heat metal x (Tfinal-Tinitial)
How much heat is necessary to raise the temperature of a 15.0g metal from 15 degrees celsius to 25.0 degrees celsius?
To calculate the heat required to raise the temperature of a metal, you can use the formula:
q = m * c * ΔT
Where:
q is the heat energy (in joules),
m is the mass of the metal (in grams),
c is the specific heat capacity of the metal (in joules per gram per degree Celsius),
ΔT is the change in temperature (in degrees Celsius).
First, we need to find the specific heat capacity of the metal. Different metals have different specific heat capacities, so you will need to know the specific heat capacity value for the metal in question. If the specific heat capacity is not given, you may need to consult a reference source such as a physics or chemistry textbook, or an online database.
Once you have the specific heat capacity value, you can proceed with the calculations:
m = 15.0 g (given)
c = specific heat capacity (provided separately)
ΔT = 25.0 °C - 15.0 °C = 10.0 °C
Substituting these values into the formula:
q = 15.0 g * c (j/g°C) * 10.0 °C
The unit for specific heat capacity is joules per gram per degree Celsius (j/g°C). Multiply the mass, specific heat capacity, and the change in temperature to find the heat energy required (q) in joules.
