In summary, specific heat capacity is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius. It can be calculated using the formula c = Q/mΔT, and its units are joules per gram per degree Celsius or calories per gram per degree Celsius. Specific heat capacity varies among substances due to their molecular structure and composition, with substances having stronger intermolecular bonds having higher specific heat capacities. This concept is important in understanding how substances respond to heat energy and is applicable in fields such as thermodynamics, materials science, and engineering.

Thanks so very much with the help you gave me. I am truly grateful.
By the way, here's another weird problem:
A sample of with a mass of 250.g is heated to 130. degrees celcius, and dropped into 425g of H2O at 26.0 degrees C. The final temp. of the H2O is 38.4 degrees C. What is the specific heat capacity of the metal if 1.2 (10 exponent 3) Joules is lost to the enviroment.
Once again, I am clueless!

Heat lost by sample = heat gained by water + heat gained by surroundings
 
  • #3
specific heat = (4.18 x 425g of water x (38.4-26)+1.2)/(250x (130-38.4))
 

1. What is specific heat capacity?

Specific heat capacity is the amount of heat energy required to raise the temperature of one gram of a substance by one degree Celsius.

2. How do you calculate specific heat capacity?

Specific heat capacity can be calculated using the formula: c = Q/mΔT, where c is the specific heat capacity, Q is the heat energy absorbed or released, m is the mass of the substance, and ΔT is the change in temperature.

3. What are the units of specific heat capacity?

The units of specific heat capacity are joules per gram per degree Celsius (J/g°C) or calories per gram per degree Celsius (cal/g°C).

4. How does specific heat capacity differ among substances?

Specific heat capacity varies among substances due to their molecular structure and composition. Substances with stronger intermolecular bonds tend to have higher specific heat capacities, meaning they require more heat energy to change their temperature.

5. Why is specific heat capacity an important concept in science?

Specific heat capacity is important because it helps us understand how different substances respond to heat energy and how much heat energy is required to change their temperature. This information is crucial in various fields such as thermodynamics, materials science, and engineering.
