Which liquid has the lowest specific heat?
Which liquid has the lowest specific heat?
Mercury has a low specific heat capacity . Therefore it does not take much heat from the body whose temperature is to be measured. Otherwise it will lower the temperature of the body.
What substance has a low specific heat capacity?
Metals such as iron have low specific heat. It doesn’t take much energy to raise their temperature. That’s why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat.
Does liquid water have a low specific heat?
Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat, meaning it takes more energy to increase the temperature of water compared to other substances.
Where can I find specific heat of liquids?
The specific heat for some commonly used liquids and fluids is given in the table below. See also tabulated values of specific heat of gases, food and foodstuff, metals and semimetals, common solids and other common substances as well as values of molar heat capacity of common organic substances and inorganic substances.
Which is the best liquid for liquid cooling?
Water Water is one of the best choices for liquid cooling applications due to its high heat capacity and thermal conductivity. It is also compatible with copper, which is one of the best heat transfer materials to use for your fluid path. Water for liquid cooling comes from different sources.
How is the heat capacity of a liquid reduced?
Values for cP are reduced with the heat capacity of the liquid at boiling conditions at 0.1 MPa for the liquid state, and values for the gaseous state are reduced with the heat capacity of the ideal gas. The heat capacity at constant pressure of liquid water increases near the boiling temperature.
Why does water have a higher specific heat?
Heat capacity or specific heat of liquid water is substantially higher than that of most other liquid substances. When water is heated, the energy absorbed causes the hydrogen bonds to break. As the energy for these processes is not available to increase the kinetic energy, considerable heat is needed to raise the temperature.
