<u>Answer and Explanation:</u>
Initial temperature before starting T = 19oC = 292.15 K
Initial volume = 16.2L
Tyre pressure = 245kPa = 2.418atm [1atm=101.235kPa]
1. The number of mol (n)=PV/RT = (2.418 16.2) divided by (0.08205 292.15) = 1.634
2. At 55oC the pressure = (1.634 0.08205 328.15) divide by16.2 atm = 2.716 atm = 275kPa
3. The tyre will burst because the pressure exceed the tolerance limit
4.Max press = 265kPa = 2.615atm
V = 16.2L [given no significant change]
n = (2.615 16.2) divide by (0.08205 328.15) = 1.573
So, initial pressure will be = (1.573 0.08205 292.15) divide by16.2 = 2.328atm = 235.9kPa

Answer:
Because the mass of the the earth is way bigger than the mass of a classmate
Explanation:
Formula for force of gravity is;
F = Gm1•m2/r²
Where m1 and m2 are the two objects masses in question.
So, m1 may be your mass while m2 may be either the mass of the earth or your classmate.
The bigger the mass of m2, the more the force of gravity
Mass of the earth is about 5.97 × 10^(24) kg is which is so much more bigger than that of the classmate which is a human being.
Therefore, the reason why you may feel the effect of the gravitational forces between you and Earth, but not between you and a classmate is probably because the mass of the the earth is way bigger than the mass of a classmate
Answer:
Explanation:
since the problem involves pressure and volume, boyle's law is used.
P1V1= P2V2
P1 = 1.85 atm
P2 =?????
V1
<span>This example represents the challenge of survival of the fittest. In this situation, the trees have a distinct advantage due to their above average height. This puts them in the best position to gain the resources that they need to survive, most notably, the sun. The smaller plants, however, do not have this advantage, and lose out to the trees.</span>
