What does it mean when one substance has a lower specific heat than another substance?
So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
What does a low specific heat mean?
A substance with a low specific heat requires relatively little heat to raise its temperature (copper has a low specific heat).
Why do substances heat up at different rates?
Why do you think different substances heat up and cool down at different rates? Due to the bonds between alle particles (how hard it is to make particus more / amant of kin, enrgy increase). ***Specific heat capacity = the amount of heat needed to raise the temperature of 1 g of a substance by 1 degree.
What are the two types of specific heats?
Accordingly, two specific heats are defined for gases, namely specific heat at constant pressure, cp and specific heat at constant volume, cv depending upon whether the heat is transferred at constant volume or constant pressure respectively.
What substances have low specific heat?
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.
What is the specific latent heat of a substance?
The specific latent heat of a substance is the amount of energy needed to change the state of 1 kg of the substance without changing its temperature. latent heat of fusion (the amount of energy needed to freeze or melt the substance at its melting point)
What is specific heat and types?
Specific heat (s) is a particular type of heat capacity. Specific heat is the thermodynamic property, which states the amount of heat required for a single unit of mass of a substance to be raised by one degree of temperature. Temperature changes are really changes in energy.
Why do metals have low specific heats?
Metal atoms in pure metal are very close together and are able to transfer heat easily via conduction from one atom exciting the other atoms next to it. So the amount of energy it takes to heat a metal is relatively small to that of water for example.
What does it mean if a substance has a high specific heat?
So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
Which is a higher heat substance a or B?
Substance a has A higher specific heat than substance B. With all factors equal, which requires the most energy to heat equal masses of A and B to the same temperature. Substance a A large and a small container of water with the same temperature have Different amounts of heat According to the laws of thermodynamics
What does it mean when an object has a low specific heat?
So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound. See all questions in Specific Heat.
What’s the difference between high and low heat?
Specific heat is #J/(g-^oK)#. So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it.
