A glass of milk lasts longer in cold temperature ranges.
To determine a better range of temp for keeping a glass of dairy.
Apparatus and Materials:
вЂўHot drinking water
1 ) Obtain two clean 100cm3 beakers and 2 clean 500cm3 beakers. 2 . Add 50cm3 of milk to each 100cm3 beaker.
3. Labeled the 100cm3 beakers, A and B.
4. Label the 500cm3 beakers, C and D.
5. Create a into C and load C with ice to the level of dairy in A and cover with plate. 6. Place B into Deb and fill D with hot water up to the level of dairy in M and cover with menu. 7. Examine both sets of milk every 30 minutes and record observations within a suitable desk.
The a glass of milk in the hot water (beaker setup B & D) ought to spoil first, because based on the speculation; a glass of milk lasts longer in cold temperatures.
