#10

Front (Question)

1st Law of Thermodynamics

Back (Answer)

energy cannot be created or destroyed

#11

Front (Question)

2nd Law of Thermodynamics

Back (Answer)

when converting from one form to another there is always a loss of useful energy; entropy a measure of the amount of energy which is unavailable to do work

#12

Front (Question)

Potential energy

Back (Answer)

energy matter has because of its position

#13

Front (Question)

Kinetic energy

Back (Answer)

energy contained in moving objects

#14

Front (Question)

Forces that drive the transition phases in water from solid to gas

Back (Answer)

temperature and pressure; sublimation: endothermic phase transition

#15

Members of the halogen family

Back (Answer)

fluorine, chlorine, bromine, iodine, and astatine

#19

Front (Question)

What are halogens

Back (Answer)

reactive nonmetallic elements that form strong acidic compounds with hydrogen, thus producing simple salts

#20

Front (Question)

Members of the noble gas family

Back (Answer)

electrons

#22

Front (Question)

A hypothesis can eventually become a theory only if it can…

Back (Answer)

be proven true

#23

Front (Question)

What are the orderly steps of the Scientific Method?

Back (Answer)

• observation • question • hypothesis • design & experiment • use of statistical tests to evaluate results’ significance • acceptance or rejection

#24

Front (Question)

Atomic theory

Back (Answer)

all matter is made up of tiny invisible particles (atoms)
