Luka heats the end of each metal rod. Some of the wax will heat up, melt and drip off the rod. heat wax coating the metal rod metal rod After five minutes, he stops heating the metal rod. Here is the result. heat wax coating the metal rod metal rod (i) Luka heats each metal rod for the same amount of time. Suggest two other things he should keep the same to make it a fair test. 1 2 [2] (ii) He wants to compare how well the four metals conduct heat. Suggest a measurement he could take and the apparatus he could use. Measurement Apparatus [1]

The drivers brake suddenly. The force of friction between the and the makes the cars stop. The car with old worn tyres takes 20 metres to stop. The other car has new tyres. This car only takes 18 metres to stop. This is because the force of friction has . [2] (b) The condition of the road surface changes the force of friction. Tick ( ) the two correct statements. Water on the road surface increases friction. Oil on the road surface decreases friction. Ice on the road surface does not change friction. Rougher road surface increases friction.
