How do you classify matter?
Matter can be classified according to physical and chemical properties. Matter is anything that occupies space and has mass. The three states of matter are solid, liquid, and gas. A physical change involves the conversion of a substance from one state of matter to another, without changing its chemical composition.
What is relationship between mass and volume?
We can say that the volume of the object is directly proportional to its mass. As the volume increases the mass of the object increases in direct proportion. The gradient of the graph equals the density of the material.
What are the basic units of mass?
In the metric system of measurement, the most common units of mass are the gram and kilogram.
What is the formula of mass in chemistry?
MASS OF A SUBSTANCE = VOLUME X DENSITY.
What is mass and weight in physics?
The mass of an object is a measure of the object’s inertial property, or the amount of matter it contains. The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it.
What is the formula for weight in physics?
The most common definition of weight found in introductory physics textbooks defines weight as the force exerted on a body by gravity. This is often expressed in the formula W = mg, where W is the weight, m the mass of the object, and g gravitational acceleration.
What is weight in physics class 9?
The weight of a body is the force with which it is attracted towards the centre of the earth. The force of attraction of earth on a body is called as weight. W=m*g. S.I. unit of weight is Newton or kg m/s2. Weight of 1 kg mass is 9.8 Newton.
What is weight in physics short?
Question 19 Solution: The weight of a body is the force of gravity on it. The weight of a body is not constant,it changes from place to place. The S.I unit of weight is newton (N).
What is density Class 9?
*Density is a characteristic property of a substance. *The density of a substance is the relationship between the mass of the substance and how much space it takes up. *Density equals the mass of the substance divided by its voloume D=m/v. Mass per unit volume of a substance is called its density.
