1.67377x10-27 kilogram(kg) or 1.67377x 10-24 gram(g)
density is the kilogram per cubic metre means mass divided by volume.
mathmatically= density= mass/ volume
rough = m/v
Answer:
evaporation
Explanation:
The process of evaporation is as a result of water absorbing energy from the sun.
The process is a phase change in which liquid water changes into gaseous form.
- The water in gaseous form is called vapor
- This water cools and condenses in the atmosphere as it loses the energy it has gained.
- For evaporation to take place, water must absorb energy from the sun or other heating bodies.
- This will then cause vaporization of the liquid water into a gaseous form.
Answer:
V₂ =279.4 cm³
Explanation:
Given data:
Initial volume = 260 cm³
Initial temperature = 22.0°C
Final temperature = 44.0°C
Final volume = ?
Solution;
22.0°C (22+ 273 = 295k)
44.0°C(44+273 = 317k)
Formula:
According to Charles's law
V₁/T₁ = V₂/T₂
Now we will put the values in formula:
V₂ = V₁×T₂ / T₁
V₂ = 260 cm³ × 317k / 295k
V₂ = 82420 cm³. k / 295k
V₂ =279.4 cm³
A: Atoms and molecules is the correct answer.
