Which scale is being described? water freezes at 32 . water freezes at 0 . water freezes at 273 .

In Fahrenheit scale water freezes at 32°. In Celsius scale water freezes at 0°. and kelvin scale water freezes at 273.

Three most commonly  used temperature scale are Celsius scale, Fahrenheit scale and kelvin scale. The freezing point and boiling point of water on Celsius scale are 0° C and 100°C at sea level. The freezing point and boiling point of water on Fahrenheit scale are 32° F and 212°F at sea level. The freezing point and boiling point of water on kelvin scale are 273 K and 373 K at sea level.

f=gm1m2/d^2 it d

f is force g is gravitaiton constant, m1 is mass of first object, m2 is mass of second object. d is distance between two object

when insulating materials rub against each other, they may become electrically charged . electrons , which are negatively charged, may be 'rubbed off' one material and on to the other. the material that gains electrons becomes negatively charged. the material that loses electrons is left with a positive charge.
