Question

question 1
to measuring the volume of a liquid, you should use a a graduated cylinder. when reading the measurement, you should look at the \bottom\ of the meniscus (curve in liquid). this liquid often curves because the liquid is sticking to the sides of the glass walls.
water displays this property of \sticking to something else\.
what is the name of this property?
o cohesion
o adhesion
o surface tension

question 2
because water is more resistant to temperature changes than other substances, large bodies of water help to regulate the air temperature. what property of water gives it this characteristic?
o surface tension
o cohesion
o thermal regulator
o adhesion

Analyze Question 1

The question asks for the name of the property where water displays "sticking to something else" (specifically, sticking to the glass walls of a graduated cylinder to form a meniscus).

• Cohesion is the attraction between like molecules (water sticking to water).
• Adhesion is the attraction between different molecules (water sticking to glass).
• Surface tension is a result of cohesive forces at the surface of a liquid.

Therefore, the property of sticking to another substance is adhesion.

Analyze Question 2

The question asks which property of water allows it to be highly resistant to temperature changes, helping large bodies of water regulate air temperature.

• Specific heat capacity (often related to thermal regulation properties) is the amount of heat energy required to raise the temperature of a substance. Water has a high specific heat capacity due to hydrogen bonding.
• Among the choices: "surface tension", "cohesion", "thermal regulator", and "adhesion".
• While "high specific heat capacity" is the standard chemical term, "thermal regulator" is the option provided here that describes this functional characteristic of resisting temperature changes to stabilize environments.
