Which of the following has the greatest heat capacity?
a. 1,000 g of water
b. 1,000 g of steel
c. 1 g of water
d. 1 g of steel

a. 1,000 g of water

Explanation:

Heat capacity is defined as the amount of heat required to raise the temperature of a substance through 1 degree Celsius.

Q= heat gained

m= mass of the substance

c = heat capacity

Heat capacity of water =  

Heat capacity of steel =  

Hence 1,000 g of water will have greatest heat capacity.

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.
