Chemistry Questions 1. Explain what is happening to the water molecules in the flat areas of the line on your graph during the phase changes from solid to liquid and liquid to gas. The water molecules are currently gathering potential energy to change from the differing states of matter. Due to thermal equilibrium‚ the water would need a set amount of energy to break through the changes in matter. This is why temperature slows down in these phase changes. 2. When the ice is melting is it releasing heat or absorbing heat

Fossils Fossils are the remains of ancient organisms‚ usually animals and plants but there are also minute bacteria and occasionally fungi. They are preserved by natural processes of burial. Most are entombed in sediment i.e. mud‚ silt or sand which with time transforms into a sedimentary rock such as sandstone. Rarely‚ fossils are enclosed in ash erupted from volcanoes‚ resin that oozes from trees and hardens into amber‚ or natural tar seeping from the ground. Normally only the resistant hard
