When energy is removed what does the decrease in energy causes the particles in that state to do?
When energy is removed, the particles involved lose kinetic energy-they slow down.
Why does adding heat cause particles to vibrate faster?
Heat is a form of energy, you are adding energy to the system, this causes the particles to vibrate faster.
What are the sources and uses of sound?
What are the sources and uses of sound energy?" s ound energy causes the impulses to be hear from the vibrating system What are the sources and uses of sound energy?"
Which system shows a transformation from chemical to electrical and light energy?
A car battery causes the headlights to shine
Which change of state causes cooling to the atmosphere?
Melting and evaporation of water. They both absorb energy to increase the internal enthalpy.
Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.
You say all systems try to go to their stabler state and the Entropy of Universe is increasing how do you justify both the statements?
The state of maximum entropy of a system is the state when all the energy available to a system to do work is dissipated and is evened out with that of the surroundings. Therefore, the ability to do work relates to the difference in energy levels between a system and its surroundings. A system will carry on working for as long as there is energy difference between it and its surroundings. When the energy of a system and its surroundings evens out, the system ceases to function. All functional systems try, but fail to reach that equilibrium. The Universe as a system is no different. However, the energy which causes the universe to expand -- termed dark energy, which source remains unknown, cause the Universe to do work on its surroundings. Therefore, as a system, the Universe must receive or must have received its energy from its surroundings.
What causes changes state of water?
Addition or removal of heat energy.
When energy is removed what does the decrease in energy causes the particles in that state to do?
When energy is removed, the particles involved lose kinetic energy-they slow down.
What causes matter to change its state?
Temperature. Temperature causes matter to change state.
Can potential energy can be calculated from the change in state of a system?
True
Can potential energy be calculated from the change in state of a system?
True
When an atom absorbs energy that causes one of its electrons to move to a higher energy level the atom is said to be in?
Excited state
What does law conservation of energy state?
In a closed system, energy can neither be created nor destroyed.
What state of law of conservation of energy?
In a closed system, energy can neither be created nor destroyed.
Thermal energy added to a substance that is not changing state causes the substances temperature to do what?
To increase.
The addition of heat energy to a system always causes the temperature of that system to increase.?
Yes. Adding heat will increase temperature.
