What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What does specific heat of a substance represent?
The ability of a substance to hold heat.
Why specific heat capacity increase with temperature?
Specific heat capacity is by definition a per-unit-mass property. Therefore it does not depend on the mass of the substance.
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.
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 factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
What does the specific heat of substance represent?
The ability of a substance to hold heat.
What does specific heat of a substance represent?
The ability of a substance to hold heat.
What variable represent specific heat?
The unit for the specific heat capacity is J/kg.K.
Which substance having high specific heat capacity?
A common substance with a high specific heat is water. There are a few substances that have a higher heat capacity than water, though, such as lithium and ammonia.
When does the thermal capacity of a substance become equal to its specific gravity?
Thermal capacity is equals to the product of the mass of the body and its specific gravity. Thus, specific heat is equals to the thermal capacity divided by the mass of the body. Now, if the mass of tue body be unity then specific heat will be equals to the thermal capacity of the body. So, thermal capacity of unit mass of a substance is equals to its specific heat
What is the quantity of heat energy required to raise the temperature of a unit mass of a substance?
If the substance is water, this is the kilocalorie (1000 calories). One calorie is the heat to raise one gram of water by 1 deg C. Other substances don't have the same specific heat capacity as water, so you have to correct for that, first find out the heat capacity (specific heat) for the substance you are dealing with.
What property of a substance does its specific heat capacity describe?
How much heat it takes to raise the temperature
What is used to find the specific heat capacity of a substance?
The equation for specific heat is: C = q/temp. change x mass. C is a substance's specific heat, which is a constant for every substance. q is its heat capacity in joules, temp. change is the change in temperature in degrees Celsius, and mass is in grams.
Is specific heat capacity inversly proportional to its mass?
No. Specific heat capacity is 'normalized' with respect to mass, so it's a property of the substance, regardless of the mass of the sample.
What is the amount of energy that it takes to raise temperature of 1gram of substance by 1 degree kelvin?
Heat energy, although almost any energy will become heat. The amount of energy required depends on the substance.
What is the specific heat capacity of jam?
The specific heat capacity is the energy density of a substance. Since jam has a higher specific heat capacity than the pie crust it is contained in, this is why the contents of a pie are always much hotter than the pie itself.
