IT ALWAYS MOVES FROM HOTTER TO COLDER

COLD IS JUST THE ABSENCE OF HEAT

KINETIC ENERGY IS HEAT THAT IS MOVING

GALILEO CREDITED WITH THE FIRST THERMOMETER TYPE DEVICE

LIQUID INSIDE EXPANDS AS HEAT IS ADDED

BECAUSE EXPANSION RATES ARE EQUAL

USEFUL SCALE BECAUSE WATER BOILS AT 100 AND FREEZES AT O

MOST THINGS EXPAND WHEN HEAT INCREASES

MOST THINGS CONTRACT WHEN HEAT DECREASES

WHEN WATER FREEZES PIPES OR COKE CAN WILL BURST

WHEN VOLUME INCREASES DENSITY DECREASES

FLOAT BECAUSE HOT AIR IS LESS DENSE THAN COLD

BECAUSE FROZEN WATER EXPANDS MAKING IT LESS DENSE

WHEN VOLUME DECREASES DENSITY WILL INCREASE
