To see a RED object, all the light is absorbed except the Red and that is what we see as the color True False
Dafna11 [192]

Answer: True

Explanation:

Let's begin by explaining that the vision phenomenon depends on three elements: the observer, the object and the light source.

In addition, objects have pigments, which generally absorb more light than they reflect (they absorb certain wavelengths and reflect others). Therefore, the color that a given object seems to have depends on which parts of the visible electromagnetic spectrum are reflected and which parts are absorbed.  

In this sense, the colours we see are in fact the wavelengths that are reflected or transmitted from the object.  For example, a red object has that color because when it is illuminated whith white light, the pigments on this object abrsorb all the the wavelengths of the visible electromagnetic spectrum, except red. That is why red light is the only light that is reflected from the mentioned object.

A container holds 35.8 moles of gas under 10.0 atm of pressure at 70.0 C. What is the volume of the container?
zhenek [66]
THE ANSWER

for solving this, we just use the formula of the equation of state

PV = n RT
where
P: pressure =10atm
V volume
n number of mole = 35.8 moles
R universal gas constant = 0.082
T: The temperature= 70°C= 343.15 Kelvin

therefore, for finding V
we have 
 
V= (n RT) / P = 35.8 x 0.082 x 343.15   / 10 = 100.7 ≈ 101 L

the answer is V = 101L
