Astudent uses a liquid thermometer to measure the temperature of a substance in a beaker during science class. the teacher says that the measurement is incorrect.
which are the most likely reasons the liquid thermometer could have measured the wrong temperature? check all that apply.
1. the thermometer was not calibrated electronically.
2. the software connected to the thermometer had errors.
3. the bulb of the thermometer was touching the beaker.
4. the thermometer's bulb was not submerged in the substance.
5. the student stirred the substance with the thermometer.

Explanation:

Allowing the thermometer bulb to touch the beaker will result in inaccurate readings because the thermometer will conduct heat from the beaker. This will be worse especially if the beaker is not at temperature equilibrium with the liquid inside. Also, don't handle the thermometer until the temperature levels off.

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.

the correct answer is 2 and 4
