Answer:
P₂ = 1312.9 atm
Explanation:
Given data:
Initial temperature = 25°C
Initial pressure = 1250 atm
Final temperature = 40°C
Final pressure = ?
Solution:
Initial temperature = 25°C (25+273.15= 298.15 K)
Final temperature = 40°C (40+273.15 = 313.15 k)
According to Gay-Lussac Law,
The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.
Mathematical relationship:
P₁/T₁ = P₂/T₂
Now we will put the values in formula:
1250 atm /298.15 K = P₂/ 313.15 k
P₂ = 1250 atm × 313.15 k / 298.15 K
P₂ = 391437.5 atm. K /298.15 K
P₂ = 1312.9 atm
We have a 3-colour vision which happens to be the primary colours: red, blue and yellow. So, we can see red, and that is why we see it.
To see other we just mix the different cells as if we where mixing paint to get a new colour.
Hope it was easy to understand,
Happy homework/ study/ exam!
The kinetic energy of the ball b is 12.3kJ and ball B to a is 14.2kj
First let us compute for the number of moles of butane
(molar mass = 58.12 g/mol)
number of moles = 145 g / (58.12 g/mol) = 2.49 mol
<span>We use the ideal
gas equation to calculate the volume:</span>
<span> V = n R T / P</span>
V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745
torr
<span>V = 64.35 L</span>
I’m pretty sure it’s 150 joules
