Explanation:
From the question we are told that
The first distance is
The first speed is
The second distance is
The second speed is
Generally the time taken for first distance is
The time taken for second distance is
The total time is mathematically represented as
=>
=>
Generally the constant velocity that would let her finish at the same time is mathematically represented as
=>
=>
a) Solids keep shape, liquids take shape of containers but don't spill, gases take container's shape and spill out
b) if you heat gas, speed of its molecules will increase and they'll push the container's walls stronger, so the pressure will increase when the container heated
c) Heat flows from warmer to colder bodies
d) For monatomic gases it's U=1.5nRT only, molecular gas has bonds between atoms so total internal energy increases
e) Of gases
f) m/s
g) U=5/2*nRT=37830.85 J
