What else can I help you with?
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
What is another term used for specific heat is?
Another term used for specific heat is temperature.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
Many common metals have a specific heat of what?
There is not a common specific heat among metals. The specific heat of metals ranges from .12 J / kg K for uranium to 1.83 J / kg K for Beryllium.
What is a penny's specific heat capacity?
Specific heat capacity is heat capacity per unit mass. So it depends on the exact alloy composity of your penny, and not on its size.In a typical US post-1962 penny, the specific heat capacity is about .39 kJ/kgKIn a US penny from 1864-1962, the specific heat capacity would be a little less than this. The same was true from 1837-1857.From 1793-1837, the specific heat capacity was about .39 kJ/kgK.
Will things that heat quickly have a low or high specific heat?
Things that heat quickly typically have a low specific heat capacity, as they require less energy to raise their temperature compared to substances with a higher specific heat capacity.
What is a substance that has a specific heat?
Every substance has a specific heat. The definition of specific heat is: The amount of energy, usually measured in calories, needed to raise the temperature of one gram of a certain substance by one degree Celsius.
Why do living things use enzymes instead of a heat source of activation energy?
Living things use enzymes instead of a heat source of activation energy because they speed up chemical reactions as well as the metabolism in those living things.
Do living things stay warm?
YES! living things can't be cold or they might freeze to death, yet they can't have too much, either.
Why do living things in the Arctic tend towards compactness?
To conserver heat
Can parsley grow in cold weahter?
no bc it doesnt have the heat and all living things need heat
It takes significantly more energy to heat water than other liquids or air. How could this be important for living things?
Because it hakes a lot of energy to heat the water, the water's heat capacity (amount of heat energy necessary to increase the water temperature) is higher. This allows large bodies of water (oceans, lakes, etc.) to absorb larger amounts of heat with very subtle changes in temperature. Therefore. the organisms living in the water are protected from drastic temperature changes (water absorbs the heat produced by cell activity, which regulates cell temperature). This affects other living things because water-dwelling animals are resources to other organisms (for food, material, etc.).
Machines and living things can convert stored energy into what?
Machines and living things can convert stored energy into different forms of energy such as mechanical, electrical, or heat energy, depending on the process or mechanism involved.
Will living things survive without heat?
no,if living things dont have heat,plants dont grow(food),we will freeze(no heat right?) and everyone will go extinct.heat is an evreyday thing for us,if we dont have it,we die.its part of our life cycle(not in it)we just need it.
What are the 3 important things to know about heat?
that heat is hot, heat is spelt h-e-a-t, and heat is a word
What will happen to living things if there is no heat energy?
All the living beings would die... All the humans and animals would die by freezing... Because we need heat.
By what process do living things get energy from food?
Living things get energy from food during digestion. This is an exothermic reaction in which heat and electrons are released and used as energy.
