In which temperature water has maximum specific heat capacity?
Water has the highest specific heat capacity at 25 degrees Celsius. This means that it can absorb or release a significant amount of heat before its temperature changes, making it an effective heat buffer.
What has the greatest specific heat - granite rock - sand or water?
Water has the highest specific heat, sand and granite could be very similar but there are very many types of sand so no definite relationship can be given without more information.
What phase change will the greatest amount of energy be absorbed by 1 gram of water?
The phase change where the greatest amount of energy is absorbed by 1 gram of water is during the transition from liquid to gas, known as vaporization or boiling. This process requires a significant amount of heat energy to break the intermolecular bonds and change the water molecules from a liquid state to a gaseous state.
If heat is released from water what phase change occurs?
If heat is released from water, the phase change that occurs is from gas (water vapor) to liquid (water). This is known as condensation.
Explain why a watched pot of water never boils in terms of specific and latent heats?
When you watch a pot of water, heat is being transferred to the water at a constant rate. However, as the water absorbs this heat, it first needs to reach its specific heat capacity to increase in temperature before a phase change to boiling can occur. This delay is due to the latent heat of vaporization required for the water molecules to break free from the liquid phase and transition to the gaseous phase.
How can the specific heat of water be used to determine the specific heat of an object?
By immersing the object in water and measuring the initial and final temperatures of the water, along with the mass of the water and the object, you can calculate the amount of heat transferred. Using the equation Q = mcΔT (where Q is heat, m is mass, c is specific heat, and ΔT is change in temperature), you can then rearrange the equation to solve for the specific heat of the object.
What two factors does a materials specific heat latent depend on?
A material's specific heat and latent heat depend on the type of substance and its phase (solid, liquid, or gas). Specific heat is the amount of heat needed to raise the temperature of 1 kg of the substance by 1°C, while latent heat is the amount of heat absorbed or released during a phase change at a constant temperature.
What has higher specific heat water or lead?
Water has much higher specific heat than lead. All metals have fairly low specific heat values.
What is the specific heat value for water?
The specific heat value for water is 4.18 J/goC.
Water has a relatively low specific heat?
The specific heat of water is high. An example of an object with low specific heat would be a metal pan. Since specific heat is the energy needed to raise 1g of something 1 degree Celsius, water would have a high specific heat.
What has one of the greatest heat capacities?
Water has one of the greatest heat capacities among common substances. This property allows it to absorb and release large amounts of heat without significant temperature changes, making it important for regulating climate and maintaining stable temperatures in aquatic environments.
What is the expression and value for specific heat of water?
Specific heat of water is 1 calory per gram .
