Given 10.8 grams of substance y, if the substance absorbs 231 kilojoules of energy and the specific heat of the substance is 6.55 j/g·°c, what is the change in temperature?

4. a 20-kg child is tossed up into the air by her parent. the child is 2 meters off the ground traveling 5 m/s. circle one: ke / gpe / both show your work for finding the values of each type of energy the object has:

If an atom has 12 protons and 13 neutrons

Asubstance is held in an open container. its particles move past one another at random speeds but do not leave the container. heat is removed from the system, and the particles slow down. when enough heat is removed, the particles no longer have enough speed to overcome the weak attractive forces between them. when this happens, the substance enters its solid state. the process described above is known as .
