All Types of Scales are are discussed below:
The instrument which is used to measure the temperature is known as thermometer.
Measure the mass of the rectangular wooden block in grams by using a top-pan balance.
Density of Helium
A helium-filled balloon moves upwards because the density of the helium gas is less than density of air.
Apparatus
Some irregular solids, 0-500 ml measuring cylinder, top-pan balance is required to perform this experiment.
