Answer:
In order for frost to be formed, you would need high humidity, below-freezing temperatures, a clear sky, and a calm wind. Also, note that frost mostly occurs on a surface that is solid, so I would also put in a hard surface to the answer.
Explanation:
You need the hard surface so that the frost can form, otherwise it would become something like a cloud.
You need high humidity so that there is lots of water to form on your solid surface.
You need below-freezing temperatures so that the water can freeze.
The other things are just from what the Internet told me.

Answer:
The volume of an irregularly shaped solid can be determined from the volume of water it displaces. A graduated cylinder contains 19.9 mL of water. When a small piece of galena is added, it sinks and the volume increases to 24.5 mL
Length of 1 side 1.2*10^-5km =1.2*10^-5*10^5 =1.2cm
<span>volume of the cube (1.2)^3=1.728 cm^3 </span>
<span>density= mass/volume= 1.1/1.728=0.636 g/cm^3</span>
Answer:
1st answer choice
P4O6 + 2 O2 -> P4O10
Explanation:
You need to cancel out reactants and products that are the same.
P4 cancels out because it appears in both reactants and products
We get 2 O2 in the reactants because 5-3= 2
Thus, answer choice 1 is correct.
