Because to attain the condition of zero, unbalanced force is impossible. Apart from CBSE class 9 maths solutions we also provide notes on the topics to ensure that the students understand what they are studying. According to the law of conservation of momentum. The boiling point of a liquid is defined as the temperature at which the vapour pressure of the liquid is equal to the atmospheric pressure.

Its value can be assumed as 1. force applied on the body is said to be 1 Newton. To know more about Physical Nature of Matter, visit here. During evaporation, the particles of a liquid absorb energy from the surroundings to overcome the inter-particle forces of attraction and undergo the phase change. We have seen many queries for Class 9 Science notes. In every substance, there is an interparticle force of attraction acting between the particles. Congenital disease is a)Deficiency disease b)Present from the time of birth c)Spread from man to man d)That occurs during lifetime. It is the amount of heat energy that is required to change 1 kg of a solid into liquid at atmospheric pressure at its melting point. Which condition out of the following increase the evaporation of water? Chapter 2 IS MATTER AROUND US PURE . (iv) When the pile of coin on the carom-board is hit by a striker, coin only at the bottom moves away leaving rest of the pile of coin at same place. Therefore, it very important to learn every topic clearly and at the same time, revise the subject thoroughly, in order to succeed in the exams. → A person get injured severely when hit by a moving vehicle because of momentum of vehicle due to mass and velocity. → If the resultant of applied forces is equal to zero, it is called balanced forces. January 3, 2019 January 9, 2019 study_rankers. •  According to 2nd law, this rate of change is momentum is directly proportional to force. Home / Class 9 Science / Chapter – 14 Natural Resources MCQ Test 1 Science | Class 9th. → Force can change the speed of a moving body. January 3, 2019 January 9, 2019 study_rankers. For example, by applying brakes, a running cycle or a running vehicle can be stopped. Solids undergo a phase change to form liquids. On increasing temperature, the kinetic energy of the particles of the matter increases and they begin to vibrate with a higher energy. The boiling points of the liquids decrease in the following order: B.P of water > B.P of kerosene > B.P of alcohol > B.P of petrol. Particles of matter are always in motion. Particles of matter have spaces between them, 2. The particles of which the matter is comprised influence its state and properties (physical and chemical). → Balanced forces do not cause any change of state of an object. → Force can change the shape and size of an object. Since, object is in rest, therefore, its velocity, v = 0. Therefore, the interparticle force of attraction between the particles reduces and particles get detached from their position and begin to move freely.
