a) i. What is ? [1 mark] ii. State the characteristics of the particles at [1 mark] b) What is the value of temperature, when the pressure of the gas is zero? [1 mark] c) Define the law involved in this experiment [1marks] An experiment is carried out to investigate the relationship between the pressure and the temperature of a fixed mass of gas. The graph of pressure, P against temperature, T obtained is shown in Diagram 3. Example: Paper 2 Question 1
Graph of P against θ shows that gas pressure increases linearly when temperature of the gas rises. At 0°C, gas molecules are still moving and the gas has pressure. At –273°C (absolute zero), gas molecules no longer move and do not collide with the walls of the container. Hence, gas pressure becomes zero. Textbook Physics F4 pg 160

Why is the noodle being cooked in a large amount of hot water? -large mass of hot water// large heat capacity -transfer large amount of heat to noodle [2 markah] (b) 2 kg air pada suhu 30◦C ditambah ke dalam air panas berjisim 9 kg pada suhu 95◦C. Berapakah suhu akhir air tersebut apabila mencapai keseimbangan terma? 2 kg of water at 30◦C is added to 9 kg of hot water at 95◦C. What is the final temperature of the mixture when thermal equilibrium is achieved? [2 markah] Example: Paper 2 Question 2
a) i. After the journey, what happens to the pressure of air in the tyre Increases [1 mark] ii. Give two reasons for your answer in (a) (i) -temperature of air increases due to friction -rate of change of momentum increases [2 mark] b) Name the gas law involved in (a). Gay Lussac’s Law [1 mark] c) Before the journey, the air pressure in the tyre is 200 kPa at a temperature of 30◦C. After the journey, the air pressure become 220 kPa. Calculate the temperature of the tyre after the journey. [2 marks] Diagram 3.1 shows a car tyre before travelling from Alor Star to Kuala Lumpur. Diagram 3.2 shows the same tyre after reaching the destination. Diagram 3.1 Diagram 3.2 Example: Paper 2 Question 3 = + = = 333.3 K
Diagram 1 shows a glass of ice changing into water. Diagram 2 shows a glass of water changing into ice. Based on Diagram 1 and 2, compare the changes in energy involved, phase of substances and the temperature. Based on your answer, deduce a relationship between energy, phase of substance and temperature. Name the physics concept involved.

In the past, people placed an ice pack on the forehead to bring down a fever. This method is a bit messy because we need to collect the water droplets that formed as the ice melts. Nowadays, people use cooling pads to treat fever. Diagram shows a cooling pad for fever that is used nowadays. As a researcher, you are required to design a cooling pad that can help to bring down a fever fast and is convenient to use. Suggest and explain how you would produce a cooling pad from the aspects of the type of coolant, the type of cloth, and the type of protective film used, as well as additional features that can be added. ASPECTS REASON the type of coolant – High specific heat capacity Coolant made of hydrogel Low density of coolant Absorb large amount of heat Absorbs more heat Easy to carry//Portable type of cloth –High melting point Spun lace fabric Does not melt easily Easily follow shape of forehead type of protective film used – made of diamond film Anti stick to the gel additional features Size of gel pad that fits forehead Cover forehead//More heat can absorbed KF05: MENCIPTA – Penyelesaian Masalah
