A gas sample has volume 3.00 dm3 at 101
gavmur [86]

Answer:

V₂ = 21.3 dm³

Explanation:

Given data:

Initial volume of gas = 3.00 dm³

Initial pressure = 101 Kpa

Final pressure = 14.2 Kpa

Final volume = ?

Solution;

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

101 Kpa × 3.00 dm³ = 14.2 Kpa × V₂

V₂ = 303 Kpa. dm³/  14.2 Kpa

V₂ = 21.3 dm³

Define what chemical and radiant energy is
juin [17]
Radiant energy is energy contained in electromagnetic waves. These include visible light, infrared, radio waves, ultraviolet and microwaves. ... Chemical energy is energy stored in chemical bonds between atoms.

Photosynthesis is the transformation of radiant energy to chemical energy. Plants take in water, carbon dioxide, and sunlight and turn them into glucose and oxygen. Called photosynthesis, one of the results of this process is that carbon dioxide is removed from the air.

When the temperature of an object changes by 10 °C the same temperature change in Kelvins would be
kumpel [21]
The answer to this question would be: <span> 10 °K

Kelvin and Celcius scales are different by 273</span> degrees but their ratio is the same. One degree in Kelvin is equal to one degree in Celcius. That mean,  10 °C change in Celcius would be same as <span> 10 °K changes in Kelvin too. </span>
