Match the following: i) Clinical thermometer a) A form of energy ii) Normal temperature of human body b) 100 ° C iii) Heat c) 37 ° C iv) Boiling point of water d) 0 ° C v) Melting point of water e) Kink

i)- e) The clinical thermometer is an instrument consisting of a narrow, sealed glass tube with a numbered scale having one end a bulb containing mercury which extends along the tube. The long narrow tube of the thermometer containing a kink that helps to hold the mercury, therefore helps to determine the body temperature. ii)- c) The clinical thermometer is made up of mercury and as it has the lowest melting point. It is used for clinical purposes only. This thermometer can measure the small range of temperature. It can measure the ranges between 35 ° C to 42 ° C . The normal body temperature is 37 ° C however, it can vary from 35 ° C to 37 ° C . iii)- a) The energy is a quantitative property that can neither be created nor be destroyed, it can be transformed from one form to another form and can be of many forms as potential energy, kinetic energy, frictional energy, and heat energy. iv)- b) Water is a transparent, colourless, odourless universal solvent. The water is found in the physical states on the earth. These are the solid, the liquid, and the gas. The liquid water is converted into water vapour at 100 ° C called the boiling point. v)- e) The liquid water is converted into solid water called the ice at 0 ° C . It is the freezing point of water. The melting point of water is the same as the freezing point. i) Clinical thermometer e) Kink ii) Normal temperature of human body c) 37 ° C iii) Heat a) A form of energy iv) Boiling point of water b) 100 ° C v) Melting point of water d) 0 ° C
