Answer:
True
Explanation:
The speed that electromagnetic waves will travel within any medium is the same as those without a medium. The speed of electromagnetic wave is a constant and does not depend on the material of the medium.
- Electromagnetic waves are waves that do not require a material medium for their propagation.
- They are able to pass through vacuums and mediums with particles at constant speed.
- It is mechanical waves whose speed is medium dependent.
- Mechanical waves have varying speed based on the mediums they move through.
When a liquid goes from a liquid state to a gaseous state it is called evaporation
Hopefully this will help you my friend.
PV = nRT
n = PV/RT
n = (.117)(3)/(.0821)(273+80)
n = .351/28.98 = 0.012 moles
