Calculate the energy released when a 28.9 gram piece of copper is cooled from its melting point of 1083 àC to 25.0 àC The specific heat of copper is 385 Jg àC?
1.18x10^4j
How do you calculate the energy tyransferred when 3kg opf copper is heated from 20 degrees to 220 degrees?
You look up the specific heat of copper (per mass unit). Then you multiply specific heat x mass x temperature difference.
How much heat is lost when 640 g piece of copper cools from 375 celsius to 26 celsius?
86000j
How much heat must be removed from a 200 g block of copper to lower its temperature from 150 celsius to 30 celsius?
0.385 Joules/Gram Celsius is the specific heat of copper. So, q(Joules) = mass * specific heat * change in temperature q = (200 g Cu)(0.385 J/gC)(30 C - 150 C) = - 9240 Joules -------------------------amount of heat dissipation ( answer can be positive )
When 90 kJ is removed from a 2-kg copper bar its temperature drops from 200C to 85C. The specific heat of copper is?
You are supposed to divide the energy by the product of (mass x temperature difference).

Which Has An Greater Specific Heat Water or Copper?
Water has.
What is coppers specific heat?
The specific heat of copper is 0.093 cal/g(C°) or 390 J/kg(C°).
If the specific heat of aluminum is 0.902 and the specific heat of copper is 0.268 what makes copper a better choice to use for hot water lines in your house?
This means that copper will not absorb the heat from the water as much as the aluminum. Aluminum will "steal" more heat from the water- which you do not want. You need the heat to stay with the water until it serves its purpose.
If you tie piece of copper wire a end of a exhaust.. what will happen?
If a person ties a piece of copper wire at the end of the exhaust pipe on a vehicle the copper is going to heat up. When the copper heats up it will turn a rainbow of colors.
Which of the following would be the best material to use for making tea kettles A copper specific heat 380 B iron specific heat 450 C graphite specific heat 710 D aluminum specific heat 920?
aluminium
An ancient copper coin was found to absorb 545 8 J of heat when the temperature increases 31 4C The specific heat of copper is 0387 J gC What is the mass of the copper coin?
44.9
What is the mass of a piece of copper that undergoes a 25 degrees C temp change with the loss of 428 J of energy?
q = mass * specific heat * change in temperature 428 joules = (mass)(0.385 J/gC)(25o C) = 44 grams copper ============
How do you calculate the energy tyransferred when 3kg opf copper is heated from 20 degrees to 220 degrees?
You look up the specific heat of copper (per mass unit). Then you multiply specific heat x mass x temperature difference.
Water has a temp of 4.184 and copper has a temp of 0.387. Does it takes more heat to raise the temp of the copper molecule?
These are not temperature numbers but specific heat numbers. They mean that it takes 4.184 Joules and 0.387 Joules respectively to raise water and copper of one gram by one degree celsius. So, as you can see, it takes a lot more heat to raise the temperature of water than it does of copper. Water has a very high specific heat.
