A student wants to measure the temperature change of water after adding a 10 cm block of iron to container 1 and a 10 cm3 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.
Container 1
100 ml water at 25°C
10 cm iron at 40°C
Container 2
100 mL water at 25°C
10 cm lead at 40°C
Why did the temperature increase more for container 1 even though each 10 cm block was heated to 40°C and placed in 100 mL of water at 25°C? A. Different materials can have different densities.
В. Different rates of dissolving. C different materials have different capabilities of transferring heat. D. Different materials can have different rates of sinking.

What type of weather does tropical continental air bring in summer? hot and cloudy cool and sunny hot and sunny cool and cloudy

Archeologists have discovered three sites showing conclusive evidence for the mastery of fire in tanzania, from a period slightly after the time that homo habilis was present in africa. these sites clearly were founded by homo erectus, the descendent species of homo habilis that migrated north, out of africa and into asia. homo erectus was known to have mastered fire, from ample evidence at sites in asia. there is no reason to attribute mastery of fire to homo ergaster, the descendent species of homo habilis that remained in africa. which of the following is an assumption on which the argument depends? (a) before their migration, homo erectus occupied african territory as far south as tanzania.(b) the strain of migration provided the selective pressure motivating homo erectus‘ mastery of fire.(c) homo ergaster would not have derived as much benefit from the mastery of fire as did homo erectus.(d) homo ergaster inherited all cultural knowledge from homo habilis, a species that did not have mastery of fire.(e) homo ergaster did not occupy regions as far south as tanzania until well after the time of these three sites.
