Periodic Trends

Postby Mary Becerra 2D » Sun Feb 04, 2018 3:52 pm

Is there a periodic trend when it comes to heat capacities? If so, what is it and is this useful in making calculations?

Heat capacity is an extensive property and therefore depends on the amount of a substance. Specific heat capacities of elements are different depending on what state they are in. Therefore, it is difficult to measure the periodic trends.

I don't think there is a heat capacity trend of the periodic table because heat capacities depends on different factors, such as change in temperature, the system, and its mass. As well as the substance and its phase.

like the replys above, density, atmoic structure, temperature, the states of the elements all come into play and it would be almost impossible to classify them into trends in the periodic table.

Heat capacity is an extensive property and does not necessarily have trends in the periodic table. It is the amount of heat required to raise 1 mole/gram of substance by 1 degree Celsius/Kelvin. Therefore, it depends on intermolecular forces
