IG物理实验卷常见问题总结

IG物理实验6卷，历年题型变化不是很大，有些同类型的实验问题及答案比较固定，下面就对这些问题进行总结：

1.state the property of the line that indicate X is directly proportional to Y(1)straight line

(2)through origin 2.determining the refractive index of material

Suggest one precaution that you would take in this experiment to obtain readings that are as accurate as poible(1)pins well spaced

(2)ensure pins vertical

(3)use thin lines

(4)use thin pins 3.investigating the rate of cooling of water Repeated the experiments, conditions should be controlled:(1)constant room temperature/air conditioning/humidity(2)same beaker/test tube(3)volume/amount of water(4)depth of thermometer(5)amount/rate of stirring(6)initial temperature(7)thickne of cotton wool A precaution that you would take in this experiment in order to obtain a

reliable result(1)waiting time between readings(2)wait for steady thermometer reading 4.investigating temperature changes when hot water and cold water are

mixed

Repeated the experiments, conditions should be controlled:

(1)constant room temperature/air conditioning/humidity

(2)same amount of stirring

(3)poured at same time interval

(4)constant cold water temperature

(6)same hot water temperature 5.investigating the resistance of a wire It is known that changes in temperature affect the resistance of the wire.State how you can limit the temperature changes when carrying out this experiment(1)use of low current

(2)switch off between readings
