A student wants to measure the temperature change of water after adding a 10 cm3 block of iron to container 1 and a 10 cm block of lead to container 2. Both blocks were heated to 40°C before being added to the water. The image below shows the experiment
immediately after adding the blocks.
UT
Container 1
Container 2
100 ml water at 25°C 100 ml water at 25°C
10 cm iron at 40°C 10 cm lead at 40°C
Why did the temperature increase more for container 1 even though each 10 cm3 block was heated to 40°C and placed in 100 mL
of water at 25°C?
OA.
Different materials can have different rates of sinking.
OB
Different materials can have different capabilities of transferring heat.
OC. Different materials can have different densities.
D.
Different materials can have different rates of dissolving.

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.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
