If you know the heat capacity of a necklace, what additional information do you need to determine whether it is made of gold? Select the correct answer below: A. only the mass of the necklace
B. both the specific heat of gold and the length of the necklace
C. only the specific heat of gold
D. both the specific heat of gold and the weight of the necklace

heat or electricity in the atmosphere- c.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
