WHAT ARE TWO WAYS TO GET NUCLEAR ENERGY?

NUCLEAR FUSION AND NUCLEAR FISSION?

WHAT IS THE DIFFERENCE BETWEEN NUCLEAR FUSION AND NUCLEAR FISSION?

NUCLEAR FUSION INVOLVES FUSING TWO SMALL NUCLEI TOGETHER TO FORM A LARGER NUCLEUS. NUCLEAR FISSION INVOLVES SPLITTING A LARGE NUCLEUS INTO SMALLER NUCLEI.

CAN YOU MAKE A BOMB OUT OF FUEL RODS FROM A NUCLEAR REACTOR? WHY?

NO, REACTOR FUEL IS ONLY 3.5% URANIUM 235. YOU NEED AT LEAST 90% PURITY TO MAKE A BOMB.

WHAT IS A CHAIN REACTION?

A REACTION THAT TRIGGERS OTHER SIMILAR REACTIONS

WHERE DO WE STORE SPENT (USED) REACTOR FUEL?

AT THE REACTOR WHERE IT WAS GENERATED

WHAT IS HALF LIFE?

THE LENGTH OF TIME THAT IS REQUIRED FOR HALF OF A RADIOACTIVE ISOTOPE TO DISENTEGRATE (CHANGE) TO ANOTHER ISOTOPE

WHICH WOULD BE MORE DANGEROUS, AN ISOTOPE WITH A SHORT HALF LIFE OR AN ISOTOPE WITH A LONG HALF LIFE? WHY?

ONE WITH A SHORT HALF LIFE – IT IS BREAKING DOWN FASTER AND WILL GIVE OFF MORE RADIATION

WHAT IS BACKGROUND RADIATION?

THE NATURAL RADIATION AROUND US AT ANY TIME

HOW DO WE MEASURE RADIATION?

WITH A GEIGER COUNTER

LIST THE 3 MOST COMMON TYPES OF RADIATION IN ORDER OF DANGER FROM LEAST TO GREATEST.

ALPHA BETA GAMMA

WHICH ELEMENT HAS THE MOST STABLE NUCLEUS?

IRON

WHAT IS THE PREFERRED FUEL FOR A NUCLEAR REACTOR?

URANIUM 235

WHY IS SPENT NUCLEAR FUEL MORE DANGEROUS THAN NEW FUEL RODS?

SPENT NUCLEAR FUEL CONTAINS ISOTOPES WITH VERY SHORT HALF LIVES.

WHAT IS THE DIFFERENCE BETWEEN A PURE SUBSTANCE AND A MIXTURE?

A PURE SUBSTANCE HAS A FIXED COMPOSITION. THE COMPOSITION OF A MIXTURE CAN BE VARIED.

THE DENSITY OF MERCURY IS 13.5 g/ml. WHAT VOLUME WOULD YOU NEED TO HAVE 50 GRAMS?

Density = mass/volume Volume = mass/density = 50 / 13.5 Volume = 3.7 ml

WHAT IS CHEMISTRY?

THE SCIENCE OF MATTER AND ITS INTERACTIONS.

WHAT IS THE DIFFERENCE BETWEEN A HYPOTHESIS AND A THEORY?

A HYPOTHESIS IS A GUESS (AN IDEA), WHILE A THEORY IS A PROVEN HYPOTHESIS.

WHAT IS MATTER?

ANYTHING THAT HAS MASS AND TAKES UP SPACE. YOU MATTER!!
