Answer:
Molecules must collide with the correct orientation and with enough energy to cause bond breakage and formation.
Explanation:
To find the density of an object, you need to use the equation: D = M/V. This is density equals mass over volume.
Mass: 30 g
Volume: 10 cm3
30/10 = 3
Density: 3 g/cm3
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.
The speed of the molecule increses
Answer:
B. mass, volume
Explanation:
Density refers to a physical property that is measured using a ratio of mass divided by volume so that two objects of the same size can still have very different density.
