Now suspend the test tube horizontally by two strings or wires as shown in figure. Heat the test tube with a burner until water vaporizes and the cork blows out 1.The test tube recoils in the direction of ____________. 2.Which one is having less acceleration? 3.Which one possess more velocity? 4.The principle involved in this activity

Answer 1

Answer:

i think chlorine

please mark me as brainliest answer

Answer 2

Answer:

1. The test tube recoils in the direction opposite to the direction of the cork due to Newton's third law. When the air is pushed out of the test tube, it exerts an equal and opposite force on the test tube making it recoil in the opposite direction.
2. The test tube has less acceleration because it has more mass.
3. The cork posses more velocity due to it's lesser mass.
4. The principle involved in this activity is Newton's Third Law of Motion

Hope this helps!! :)
