In general, some people equate mass and weight.
Mass is one of the principal quantities, which is related to the matter , whereas weight is a force that leads to the center of the earth (Earth's gravitational force)
Steps that can be taken to find the mass :
- 1. Weigh graduated cylinder (empty)
- 2. Pour the alcohol in the beaker into the graduated cylinder to the level of 40 ml
- 3. Weigh again graduated cylinder + poured alcohol
- 4. mass of alcohol 40 ml = mass in 3rd step - mass in the first step
Answer:
A There are more particles in the air for water vapor to cluster around.
Explanation:
- As the condensation process takes place more particles are added to the atmosphere for water vapour and condensation further leads to the build-up of clouds.
- If the sky is polluted with pollutants the condensation can raise the level of pollution by blocking the rays of the sun from reaching the ground. This affects the visibility of most of the cities.
Answer:
The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass.
Alkali metals will always contain one valence electron but the electron configuration will depend on the element
