answer: white fur works as a camouflage against the white snow, allowing polar bears an advantage when hunting for food and hiding from predators
Answer:
268.75 K
Explanation:
We are given;
- Initial pressure, P1 as 600 torr
- Initial temperature, T1 as 215 K
- New pressure, P2 as 750 torr
We are required to determine the new temperature, T2.
To solve this question we are going to use the pressure law of gases.
According to pressure law, the temperature of a fixed mass of a gas and its pressure are directly proportional at constant volume.
That is;
Pα T
Therefore;
![\frac{P_{1} }{T_{1} } =\frac{P_{2} }{T_{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%20%7D%7BT_%7B1%7D%20%7D%20%3D%5Cfrac%7BP_%7B2%7D%20%7D%7BT_%7B2%7D%20%7D)
Thus,
![T_{2} = \frac{P_{2}T_{1} }{P_{1} }](https://tex.z-dn.net/?f=T_%7B2%7D%20%3D%20%5Cfrac%7BP_%7B2%7DT_%7B1%7D%20%20%7D%7BP_%7B1%7D%20%7D)
![T_{2} =\frac{(750)(215)}{600}](https://tex.z-dn.net/?f=T_%7B2%7D%20%3D%5Cfrac%7B%28750%29%28215%29%7D%7B600%7D)
![= 268.75 k](https://tex.z-dn.net/?f=%3D%20268.75%20k)
Therefore, the new temperature is 268.75 K
Answer:
<h2>22.366 kPa</h2>
Explanation:
The final pressure can be found by using the formula for Boyle's law which is
![P_1V_1 = P_2V_2](https://tex.z-dn.net/?f=P_1V_1%20%3D%20P_2V_2)
Since we are finding the final pressure
![P_2 = \frac{P_1V_1}{V_2} \\](https://tex.z-dn.net/?f=P_2%20%3D%20%20%5Cfrac%7BP_1V_1%7D%7BV_2%7D%20%20%5C%5C)
From the question
58.6 kPa = 58600 Pa
We have
![P_2 = \frac{58600 \times 250}{655} = \frac{14650000}{655} \\ = 22366.4122... \\ = 22366](https://tex.z-dn.net/?f=P_2%20%3D%20%20%5Cfrac%7B58600%20%5Ctimes%20250%7D%7B655%7D%20%20%3D%20%20%5Cfrac%7B14650000%7D%7B655%7D%20%20%5C%5C%20%20%3D%2022366.4122...%20%5C%5C%20%20%3D%2022366)
We have the final answer as
<h3>22.366 kPa</h3>
Hope this helps you
1. Because that shows that you're a living thing because all living things can respond to stimuli.
2. Because an example of stimuli is a virus. If you couldn't respond to it (by fighting against it) you would probably die.
Hope it helps
