Answer:
40.68kPa
Explanation:
The remaining part of the question is requesting to calculate the pressure (p2) after increase in volume.
Data;
V1 = 21.3mL
P1 = 98.8 kPa
V2 = 52.7 mL
P2 = ?
Using Boyle's law,
PV = K
P1V1 = P2V2
98.8 * 21.7 = p2 * 52.7
P2 = 2143.96 / 52.7
P2 = 40.68 kPa
Note I didn't convert the values since they all have the same unit.
Answer:
Option A (They happen as the Sun hits its maximum and minimum level throughout the sky) is the correct option.
Explanation:
- Solstice seems to be the moment whereas at noon this same sun achieved its maximum as well as minimum position, actually results throughout the year's shortest as well as biggest days.
- We currently believe that perhaps the solstice seems to be an apocalyptic event, exacerbated either by the tilt of the globe’s axis and therefore its direction of movement in an elliptical orbit. Globe's rotation not everyone's travel time from either the sun was what was causing winter or even just summer.
Some other options given should not be in accordance with the given context. So, the correct approach would've been option A.

Answer:
The answer to this question is 3. Kinetic energy decreases as temperature decreases.
Explanation:
The average Kinetic energy is given by
× × T where
K = The average molecular kinetic energy of the gas (J)
= Boltzmann's constant (1.38× J/K)
T = Temperature of the gas in Kelvin (k)
When the temperature of a given mass of gas drops average kinetic energy of the molecules goes down and the average molecular speed decreases. The lower kinetic energy which is the energy of motion of the molecules indicates lower speed of the molecules.
Note that, the kinetic energy and average speed are related by the following formula
KE = ×m×v²
Where KE = Kinetic energy in Joules (J)
v = the velocity in m/s and
m = the mass of the molecule in Kg
60 I think bcz if there is 1&2 they differ 10 times
