The answer is c as this phase change refers to any change of a solid to gas.
Answer:
The correct answer is - C) the RICE formula.
Explanation:
The first aid for a patient with a sprain or strain mainly includes the RICE formula which stands for the rest, ice, compression, and elevation. In case of a sprain or strain, one is advised to rest, use ice on the location of the sprain, compression on the part of the sprain, and elevate the body part for less pain, less swelling or reducing chances of making it worst.
The other three formulas given are used in different conditions. The FITT formula used in the exercise planning, and the ABC formula used for the first aid of the heart attack or blockage of the airway.

Answer:
It's H3O+.
Explanation:
The H3O+ ion in the solution is what gives it its acidic properties ( sour taste, low pH , for example). Its known as the hydronium ion.
Answer:
length = 7*10^(-8)km
width = 4.666*10^(-8) km
Explanation:
We know that:
1 μm = 1*10^(-6) m
and
1km = 1*10^3 m
or
1m = 1*10^(-3) km
if we replace the meter in the first equation, we get:
1 μm = 1*10^(-6)*1*10^(-3) km
1 μm = 1*10^(-6 - 3)km
1 μm = 1*10^(-9)km
Now with this relationship we can transform our measures:
Length: 70 μm is 70 times 1*10^(-9)km, or:
L = 70*1*10^(-9)km = 7*10^(-8)km
And for width, we have 47.66um, this is 46.66 times 1*10^(-9)km, or:
W = 46.66*1*10^(-9)km = 4.666*10^(-8) km
