Answer:
![P_2=404 kPa](https://tex.z-dn.net/?f=P_2%3D404%20kPa)
Explanation:
Hello,
In this case, the Boyle's is mathematically defined via:
![P_1V_1=P_2V_2](https://tex.z-dn.net/?f=P_1V_1%3DP_2V_2)
Which stands for an inversely proportional relationship between volume and pressure, it means the higher the volume the lower the pressure and vice versa. In such a way, since the volume is decreased to one quarter, we can write:
![V_2=\frac{1}{4} V_1](https://tex.z-dn.net/?f=V_2%3D%5Cfrac%7B1%7D%7B4%7D%20V_1)
We can compute the new pressure:
![P_2=\frac{P_1V_1}{V_2} =\frac{P_1V_1}{\frac{1}{4} V_1} =\frac{101kPa*V_1}{\frac{1}{4} V_1} \\\\P_2=4*101kPa\\\\\\P_2=404 kPa](https://tex.z-dn.net/?f=P_2%3D%5Cfrac%7BP_1V_1%7D%7BV_2%7D%20%3D%5Cfrac%7BP_1V_1%7D%7B%5Cfrac%7B1%7D%7B4%7D%20V_1%7D%20%3D%5Cfrac%7B101kPa%2AV_1%7D%7B%5Cfrac%7B1%7D%7B4%7D%20V_1%7D%20%5C%5C%5C%5CP_2%3D4%2A101kPa%5C%5C%5C%5C%5C%5CP_2%3D404%20kPa)
Which means the pressure is increased by a factor of four.

<span>The answer is B. Convection occurs when hot/warm
water rise to the top and the cold water goes to the bottom in a vessel. This is
because hot/warm water is less dense than cold water. Additionally, convection
currents are well perceptible in air and water and fluid substances that are
poor conductors of heat</span>
Answer:
Coefficients are the numbers in front of the formulas.
Answer: pretty sure it is D
Question 9. The first one is the smallest. Anything with a negative exponent is going to be less than 1, the .00000241. The exponent tells you the number of zeroes to the right of the decimal point. Farther to right gets smaller and smaller.
Question 10. The last one is true. If the last digit is smaller than 5, drop the digit, and do not change. (If it is a 5 or larger, the digit before it would round up)
