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
What is the energy of a system by virtue of its motion?
That's called kinetic energy. The formula is: Kinetic energy = (1/2) x mass x velocity2. If mass is in kilograms, and velocity (or speed, really) in meters per second, the energy will be in Joules.
Which object had more kinetic energy the one that has a mass of 2 kilograms or the one with the mass of 4 kilograms and was lifted at a rate of 3meters per second?
If the first object is just sitting there and not moving, then it has zero kinetic energy.
Does evaporation take on or give off energy?
Moisture needs to take in energy to evaporate. That's why your skin feels cooled when it happens to sweat on your skin.
How is solar energy released?
solar energy is released by the sun
How many kilograms of energy are in tomatoes?
Energy is not measured in kilograms
How much energy is released when a substance is cooled to its original temperature?
It depends on it's original temperature and how much it was heated.
When a sample of liquid is cooled its thermal energy?
When a sample of liquid is cooled its thermal energy goes to its surroundings
What does a substance do when it is cooled?
It loses energy.
Why does soil release more energy when cooled?
When something is cool, it tries to absorb energy from it's surroundings. When something is cooled off, it releases energy during that cooling process.
When a gas undergoes adiabatic expansion it gets cooled due to?
It gets cooled because the internal energy of the system decreases.
What has the author Mary Lou Granite written?
Mary Lou Granite has written: 'Energy considerations in remodeling of owner-occupied single family dwellings, Corvallis, Oregon' -- subject(s): Energy conservation, Buildings
What are the advantages and disadvantages of an air cooled condensers over that of a fan cooled in refrigeration?
The air cooled can be more efficient because they will use less energy. They are difficult to maintain if it stays too hot.
If the energy released per uranium fission is 2.0e2 MeV how many kilograms of coal must be burned to produce the same energy as 1.0 kg of uranium?
Check this page out; it details how to get the answer: See link below.
Why are super cooled metals good conductors?
Super cooled metals are good conductors because their super cooled properties allow them to conduct electric currents without resistance. This means no loss of energy.
When a liquid is cooled the molecules in that liquid?
I assume you mean what happens to the molecules... They slow down due to the loss of kinetic energy when the liquid is cooled. When they are sufficiently cooled as to cause freezing, that's a different story.
What happens to particles when cooled?
it loses energy that makes it not move as quickly, therefore it gets smaller. that answer your question?
