What has the highest specific heat solid liquid or gas?

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. The specific heat capacities of iron, granite, and hydrogen gas are about 449 J⋅kg−1⋅K−1, 790 J⋅kg−1⋅K−1, and 14300 J⋅kg−1⋅K−1, respectively.

What state of matter has the highest specific heat capacity?

Water has the highest specific heat capacity of any liquid. Specific heat is defined as the amount of heat one gram of a substance must absorb or lose to change its temperature by one degree Celsius. For water, this amount is one calorie, or 4.184 Joules.

What is the order of entropy in solid liquid & gas?

Answer: Solids have the fewest microstates and thus the lowest entropy. Liquids have more microstates (since the molecules can translate) and thus have a higher entropy. When a substance is a gas it has many more microstates and thus have the highest entropy.

Which of the following substances has the highest specific heat capacity?

water
From the given options, water has the highest specific heat capacity.

What is specific heat of gas?

The specific heat of a gas at constant pressure is the amount of heat required to raise the temperature of one mole of a gas by unit temperature at constant pressure.

Do solids or liquids have higher specific heat?

In general the heat capacities of solids and liquids are higher than those of gases. This is because of the intermolecular forces operating in solids and liquids. According to a theory first suggested by Einstein, this vibrational energy has the value 3RT, while the heat capacity is given by 3R = 24.9 J K–1 mol–1.

What happens to entropy during the reaction caco3 s → Cao’s )+ co2 g?

The entropy of the system increases in the decomposition of calcium carbonate to calcium oxide and carbon dioxide.

What is the entropy of a solid based on?

The entropy of a perfectly-ordered solid at 0 K is zero. The absolute entropy of a substance at any temperature above 0 K must be determined by calculating the increments of heat q required to bring the substance from 0 K to the temperature of interest, and then summing the ratios q/T.

Which substance has the highest specific heat Class 11?

As the pressure increases more heat is required to increase the temperature of the body. So clearly water has the maximum specific heat among the options at room temperature and at atmospheric pressure. So, the answer to the question is option (A) Water.

How many specific heats does a gas possess?

Solids and liquids have only one specific heat, while gases have two specific heats: In the case of solids and liquids, a small change in temperature causes a negligible change in the volume and pressure, hence the external work performed is negligible.
