The reason why the sky is blue is because it is reflecting off of the sky and when it is evening its losing light
Answer:
A
Explanation:
Clear glass reflects light, but frosted glass absorbs light.
An ideal diatomic gas at 80 k is slowly compressed adiabatically and reversibly to half its volume. The final temperature is 104.8k
<h3>Calculation of final temperature </h3>
The formula used for compression is:-
TV^(γ-1)=C
where;
T= temperature=80k
V=volume(given volume is half of its original volume i.e v/2)
γ=CP/CV= ( 7.R/2)/(5R/2)=7/5
C= constant
using the given values in the formula;
80 x V^[(7/5)-1]=T(final) (V/2)^[(7/5)-1]
80=T(final) x (V/V2)^(2/5)
80=T(final) x (1/2)^(2/5)
T(final)= 80 x (2)^2/5
T(final)= 80 x 1.31
final temperature =104.8k

Answer:
Combustion is the reaction type if you meant to put a "=" in between C3H2 and H2O
The planet that would have a diameter of approximately 12 cm is Saturn.
<h3>What is a scale model?</h3>
A scale model is a model which is used to represent another object using a given scale.
Scale models can be used to make small object bigger or larger objects smaller.
Considering the scale model of the planets where 1 centimeter (cm) is equal to 10,000 kilometers (km);
1 centimeter = 10,000 kilometers
12 centimeter = 1.2 × 10⁵ kilometers
The planet with a diameter of approximately 1.2 × 10⁵ kilometers is Saturn.
In conclusion, scale models are used to model objects.
