Pl ! ! over time, rocks transform from one type to another through the geological processes that occur on earth. consider this fact as you read and respond to this lesson's discussion prompts. imagine that you are a rock. what type of rock would you be and where would you be located—for example, would you be deep within the earth or on the surface? what were you like before you became the rock you are now and what type of rock will you be in the future? be sure to describe the processes involved in the changes you have gone through to get to where you are now, as well as the changes you will undergo as you change your rock type again.

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]

Observation and experimentation have led many scientists to accept a theory about the origin of the universe. this theory is called the big bang theory. scientific evidence collected and observed by scientists around the world suggests that the universe is ever expanding from a hot and dense initial state. what makes this a scientific theory?
