A 1.0Kg of solid copper is heated at atmospheric pressure. If it's temperature increases from 20° to 50°c. (a) find the work done by copper, (b) what quantity of heat is transferred into copper? (c) what is the increase in internal energy of copper?

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

Arock collection comes from which part of earth?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
