Fill the third basin with cold water from the tap (水龙头). Now place the basins on the table. Put your right hand in the hot water. Put your left hand in the cold water. You will find that your right hand feels hot and your left hand feels cold. After twenty seconds move both your hands in the lukewarm (微温的) water. What do you feel? Your left hand feels warm and your right hand feels cold. But both hands are in the same basin of water. |
