50 Units Of Measurement Worksheets For 7th Class On Quizizz Free Si unit of density is kg m3 1 g cm3 = 1000 kg m3 density: a characteristic property of a substance: it is the product of the no. of molecules per unit volume of that substance. application of density in real life: flotation of an iceberg. flotation of a ship made of iron. swimming in sea water. The unit of mass in s.i. system is kilogram (kg). higher units of mass are quintal and metric tonne. the weight of body changes with acceleration due to gravity. weight is zero at the centre of the earth. mass per unit volume of a substance is called density of the body. Question 17: a car travels a distance 15 km in 20 minutes. find the speed of the car in (i) km h 1 (ii) m s 1 [level: hard]. Worksheets that mix all four operations in applied science contexts, such as density or volume calculations, are particularly effective because they require students to decide which rule to apply rather than follow a single procedure automatically.
