IGCSE Physics Past Paper(alternative to practical)0625/62-May/June2025-CIE-Solution of Q1

In this video, we will solve IGCSE physics past paper alternative to practical 0625/62, May/June 2025 Question 1. We will discuss 1. A student determines the internal diameter d of a test-tube. (i) fills a measuring cylinder with water up to the 100 cm3 mark pours some water from the measuring cylinder into the test-tube. measure the height h in centimetres to the nearest millimetre. Record your result in the top row of Table (ii)Take the reading R of the volume of water remaining in the measuring cylinder. Record your result in the top row of Table (iii)Calculate the volume V of water poured into the test-tube. Use the equation: V = (100cm3 – R). Record your result in Table (b) The student: • adds more water from the measuring cylinder into the test-tube • measures the new height h of the water in the test-tube • measures the new reading R of the water remaining in the measuring cylinder • calculates the volume of water V in the test-tube • repeats the procedure for three more values of h, R and V. The student’s results are shown in Table 1.1. It is important to avoid line-of-sight (parallax) errors when reading the scale of the measuring cylinder. Describe how such errors are avoided. You may draw a diagram. Plot a graph of V/cm3 (y-axis) against h/cm (x-axis). Start your axes at the origin (0,0). (i) Draw the best-fit straight line. (ii)Determine the gradient G of your line. Show all working and indicate on the graph the values you use. The internal diameter d of a cylinder is given by the equation d = k G , where k = 1.13 cm. Calculate d for the test-tube. Suggest one reason why your calculated value for d is only approximate.
