Specific Heats Cv and Cp for Monatomic and Diatomic
The molar specific heat capacity of a gas at constant volume Cv is the amount of heat required to raise the temperature of 1 mol of the gas by 1 C at the constant volume. Its value for monatomic ideal gas is 3R2 and the value for diatomic ideal gas is 5R2. The molar specic heat
The specific heats, and , and vary with the temperature, the variation being different for each gas. The general trend is that heavy molecular weight gases i.e., more complex gas molecules than those listed in 2 or 3, have values of closer to unity than diatomic gases, which, as can be seen above, are closer to unity than monatomic gases.

The specific heat of air at constant volume is expressed by the symbol cv c v and its value is 0.718 kJkgK. 0.718 k J k g K. The ratio of the specific heat at constant pressure to the ...
Aluminum hydroxide is an inorganic salt used as an antacid. It is a basic compound that acts by neutralizing hydrochloric acid in gastric secretions. Subsequent increases in pH may inhibit the action of pepsin. An increase in bicarbonate ions and prostaglandins may also confer cytoprotective effects.
CALCULLA Specific heat of substances table
Specific heat is a property of substance the so-called material constant. Also, it depends on external conditions pressure and temperature. The specific heat tells us how difficult it is to heat the given body.Substances with low specific heat change their temperature easily, whereas high ones require much more energy delivered to achieve identical effect.
Times are specific heat, which is 900 and then were gonna take that, add it to our mass and our specific heat for water. So were gonna go ahead and add So our mass of water 0.825 kilograms. Time for a specific heat, which is 4186 and then were gonna take all this. And since our temperature change for the aluminum and the water is the same on ...
