For 0.37 moles of oxygen (o2) gas at room temperature with active translational and rotational degrees of freedom. how much heat must be added to in order to raise its temperature by 15 k with the pressure kept constant? a. 100.4jb. 161.5j c. 69.2j d. 19.4j e. 935.3j

To solve this problem we will use the concept given for the exchange of heat given based on the number of moles, the specific heat and the temperature change.

Where,

= Specific Heat

= Change in temperature

n = Number of moles

For diatomic and polyatomic ideal gases we get: diaatomic:

Here R is the Gas ideal Constant,

Therefore replacing we have,

The correct answer is B.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
