WHICH LIQUID FREEZES THE FASTEST TAP WATER WATER

WHICH LIQUID FREEZES THE FASTEST: TAP WATER, WATER WITH SALT, OR WATER WITH SUGAR?

TAP WATER FREEZES AT THE TEMPERATURE 0 DEGREES FAHRENHEIT AND UNDER. WATER WITH SALT ONLY FREEZES AT THE TEMPERATURES 21 DEGREES FAHRENHEIT AND UNDER. WATER WITH SUGAR FREEZES WITH TEMPERATURES -31. 836 DEGREES FAHRENHEIT AND UNDER. 1 GRAM OF A SOLUTE PER LITER DECREASES THE FREEZING POINT BY -33. 696 DEGREES FAHRENHEIT. THE MORE OF THE SOLUTE ADDED THE MORE THE FREEZING POINT DECREASES

IF I PUT 4 OUNCES OF TAP WATER IN THREE CUP, ONE WITH SALT, ONE WITH SUGAR, AND ONE WITH NOTHING BUT TAP WATER. THEN THE CUP WITH ONLY TAP WATER WILL FREEZES THE FASTEST.

I. THREE CLEAR GLASS CUPS II. ONE FREEZER III. 355. 188 MI OF WATER IV. ONE CUP BREAKER V. TAP WATER VI. SALT VII. SUGAR VIII. SPOON IX. TIMER

a) b) c) d) GATHER ALL MATERIALS PUT 118. 394 ML OF WATER IN EACH CUP PUT TWO TEASPOONS OF SALT IN ONE CUP PUT TWO TEASPOONS OF SUGAR IN ONE CUP e) PUT A NAME TAG ON EACH CUP f) g) h) PUT ALL CUPS IN THE FREEZER CHECK CUPS EVERY 10 MINUTES FOR 1 HOUR i) j) TAKE PICTURES RECORD DATA REPEAT B-F FOR THE REST OF THE TRIALS

i. ii. INDEPENDENT- THE INDEPENDENT VARIABLE IN MY EXPERIMENT IS THE TYPE OF LIQUID. DEPENDENT- THE DEPENDENT VARIABLE IS THE AMOUNT OF TIME IT TAKES THE WATER TO FREEZE. iii. CONTROL- THE CONTROL VARIABLES ARE THE CUPS AND THE FREEZER.
