12 Questions
What is mass and how is it measured?
Mass is the amount of matter in a body, and it is measured in grams or kilograms using a balance.
What is weight and how is it different from mass?
Weight is a measure of the amount of Earth's attraction to a body. It is different from mass because it varies depending on the gravitational force.
How does weight differ on the moon compared to Earth?
Weight on the moon is less than on Earth due to the Moon's weaker gravitational force.
How is the volume of a liquid measured?
The volume of liquid is measured by pouring it into a graduated cylinder and reading the level where it reaches.
What is the unit used to measure weight and give an example conversion?
Weight is measured in newtons, with 1 Newton being approximately equal to Earth's gravitational force for a specific mass.
What is the space occupied by a body called and how is it measured?
The space occupied by a body is called volume and is measured in cubic centimeters (cm^3).
How is the volume of a regular object like a parallelepiped calculated?
The volume of a regular object like a parallelepiped is calculated by multiplying its length, width and height.
What technique is used to measure the volume of an irregular object?
The irregular object is immersed in water placed in a graduated cylinder, and the change in water level is measured.
What is the characteristic of particles in a solid state?
The movement of particles in a solid state is very limited; they vibrate in place.
How does the shape of a liquid differ from that of a solid?
Liquids do not have a specific shape, and take the shape of the container they are placed in.
Describe the motion of particles in a gaseous state.
In a gaseous state, the particles are in constant motion, spreading in every direction.
Which state of matter is the least dense?
The gaseous state is the least dense of the three states of matter.
Learn about the concepts of mass and weight, how they are measured, and the difference between the two. Understand how scientists use balances to measure mass and how weight is a measure of Earth's attraction to an object.
