Answer: The final pressure is 0.81 kPa
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 0.58 kPa
= final pressure of gas = ?
= initial volume of gas = v
= final volume of gas = 
= initial temperature of gas = 
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The final pressure is 0.81 kPa
The change in heat is simply equal to:
change in heat ΔH = final enthalpy – initial enthalpy
ΔH = [280.25 g * 4.18J/gC * (17.5°C)] – [280 g * 4.18J/gC
* 13.5°C]
ΔH = 4,699.89 J = 4.7 kJ
<span>Hence heat released is about 4.7 kJ</span>
Easy it’s 86 so the third option
If the stigma is messed up it is hard for bees or insects to pollinate because the way they pollinate is by eating the nectar from the stigma and stick the pollen on their body and stick it on the stigma.
But if there is no stigma=no pollination
A good example of a model is a lily
