What is the relationship between specific heat and rate of heating?
change in temperature does not effect specific heat. for example,specific heat of water is 4.14 j/g.k at any temperature
Is the heat capacity of a body the same as its specific heat capacity?
The heat capacity depends on the mass of a material and is expressed in j/K.The specific heat capacity not depends on the mass of a material and is expressed in j/mol.K.
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
What does it mean to say that a material has a high or low specific heat capacity?
The specific heat capacity of a substance is the amount of energy required to increase the temperature of a said substance 1o K. The capacity is measured in kilojoules divided by kilogram time degrees Kelvin (kJ/Kg k). So, if the specific heat capacity of a substance is high, it requires a very large amount of energy to increase the temperature, and if it has a low specific heat capacity, the required energy will be lower.
Liquid magma flow upward through the crust because it is less dence than the solid material around it?
less dense than the solid material around it
What is the relationship between specific heat and rate of heating?
change in temperature does not effect specific heat. for example,specific heat of water is 4.14 j/g.k at any temperature
Effect of temperature on specific heat of material?
The effect of temperature on specific heat of material is referred to as specific heat capacity.
What happens to the specific heat of a material if mass is doubled?
There is no change; specific heat is an intensive property of a material, independent of the amount.
Heat transfer in fluids due to less dense material rising?
Convection.
What does heat capacity depend on?
Mass and specific heat.
Why is it that wood feels less hot than metal?
Because it is less dense. The ability of a material to absorb or retain heat is governed by its molecular density, and is known as "specific heat". Wood, which is cellulose, has a much lower density than metals, and will both heat more slowly and cool more quickly in air. Lighter metals, such as aluminum, similarly display a substantially lower ability to retain heat than denser metals such as iron. When cooling materials, light metals or porous wood can be effectively cooled by the air (a low specific heat), while other denser substances are more effectively cooled by water (higher specific heat, and can absorb heat by evaporating).
Is specific heat the same as specific gravity?
No. Specific heat is the amount of heat required to raise 1 kg of material by 1 K at constant pressure, while specific gravity is the ratio of the material's density to a reference density (typically water).
Is the heat capacity of a body the same as its specific heat capacity?
The heat capacity depends on the mass of a material and is expressed in j/K.The specific heat capacity not depends on the mass of a material and is expressed in j/mol.K.
Would it be better to have pots and pans made from material with a high specific heat capacity or low specific heat capacity?
Higher Heat
What is the ability of a substance to absorb heat energy is called?
Specific heat capacity describes how much heat energy that is needed to raise the temperature of material.
Do convection currents form in the mantle when heated materials become more dense?
Actually, heated materials are less dense. When heat is applied to a substance such as liquid, it becomes less dense. It is this less dense and heated material that rises because it weighs less. The part of the mantle that is more dense would be any substance that is cooling and is sinking down.
The specific heat of the material is?
specific heat content is calculated by the joules of energy required to change the temperature of one cubic centimeter of the material 1 degree Celsius.
