Options for the question are not given. They are as follows:
sublimation
condensation
deposition
evaporation
melting
Answer:
sublimation
Explanation:
When a matter changes its state directly from solid to gaseous without encountering the liquid phase, the phenomenon is called as sublimation. It can be observed in places which have below freezing temperature, dry winds and sunlight. Dry air with less relative humidity leads to direct conversion of snow into vapor. Heat required is supplied by the sunlight. Since here the clothes first froze and then directly dried in the above mentioned environmental conditions, it is a case of sublimation change of state.
It is crucial to be aware of and respect the environment because you live off of it. Our earth provides us air, energy, food, and the resources we need to live. When we don't keep our environment clean, and disrespect it, it won't be in as good condition as it should be, and could potentially die out from being mistreated. We need to be aware of our environment to know what we need to do to cater to its needs, so it can cater to ours.
An airborne pathogen would be much more dangerous than that of a foodborne and person to person. Why? Because there is a higher risk of contracting it. With person to person, you could avoid infected people all-together, but with airborne, it's more complex than that. Obviously, the molecular make-up is different as-well, but this is in regard to which pathogens you are talking about.
Answer:
The half-life (t1/2) is the time taken for the activity of a given amount of a radioactive substance to decay to half of its initial value. The mean lifetime (τ, “tau”) is the average lifetime of a radioactive particle before decay. The decay constant (λ, “lambda”) is the inverse of the mean lifetime
