Four beakers have water at 20c. a piece of metal is dropped into the water in each beaker. the table below shows the initial temperature of the four metals

Metal D.

Explanation:

Metal D is below 20C, so when it is dropped into the 20C water, it will begin to move close to that heat level, although it will not achieve it. But it still receives heat.

the abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. the region occupied by the abdomen is termed the abdominal cavity. the stomach secretes acid and enzymes that digest food. ridges of muscle tissue called rugae line the stomach. the stomach muscles contract periodically, churning food to enhance digestion. the pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
