Answer:
a and b
water has a higher surface tension than veg oil
isopropyl alcohol boils more esier than water
Explanation:
just did the test trust me :)
A and B statement is true about the substances in this experiment.
A. Water has a higher surface tension than vegetable oil.
B. Isopropyl alcohol boils more easily than water.
A substance is a specific type of stuff with specific features. A substance is any pure compound or element. Water is a pure material and a hydrogen-oxygen combination.
A. Water has a higher surface tension than vegetable oil.
Reason:
The force operating at a border between two phases is measured as surface tension. Surface tension at liquid-air interfaces is caused by the higher attraction of liquid molecules to each other than air molecules.
Due to the relatively strong attraction of water. Hence molecules of water have high surface tension.
B.. Isopropyl alcohol boils more easily than water.
Reason:
isopropyl alcohol is a highly flammable liquid that evaporates significantly faster than water, especially when heated. The boiling point of isopropyl alcohol is lower than that of water.
Alcohol is more volatile than water. Hence Isopropyl alcohol boils more easily than water.
