Does higher specific heat absorb more heat?

Specific heat is Jg−oK . So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it.

Is it better to have a higher heat capacity?

The higher the specific heat capacity of the material, the more energy can be stored with a given temperature difference. So, a high heat capacity makes the regenerator more efficient.

What does having a higher specific heat capacity mean?

A high specific heat capacity means it can hold a large amount of thermal energy in for a low mass or temperature change.

Why does specific heat increase with temperature?

The heat goes first into increasing the kinetic energies of the molecules. As the substance heats up, the average kinetic energy of the molecules increases. The collisions impart enough energy to allow rotation to occur. Rotation then contributes to the internal energy and raises the specific heat.

Why is high specific heat important to life?

Explanation: The high specific heat of water means that it requires a large amount of heat to raise the temperature of water. This helps the temperature of the environment from becoming too hot or too cold. The fact that water is such a good solvent for polar molecules allows the chemistry of life to occur.

What does it mean to have a high specific heat quizlet?

What does a high specific heat capacity mean? A high specific heat capacity means more energy is required for each degree temperature change. The greater the mass of substance being heated the more energy required for each degree temperature change.

Does specific heat capacity decrease with temperature?

Specific heat capacity often varies with temperature, and is different for each state of matter. Liquid water has one of the highest specific heat capacities among common substances, about 4184 J⋅kg−1⋅K−1 at 20 °C; but that of ice, just below 0 °C, is only 2093 J⋅kg−1⋅K−1.

Why is specific heat more useful than heat capacity?

For example, more energy will be needed to heat a 5 gallon tank of water 1 degree C than would be needed to heat one cup of water by 1 degree C. On the other hand specific heat capacity will be more useful because it is the amount of energy needed to raise the temperature a gram of that object by 1 degree C.
