Answer:
when you bring two objects of different temperatures together, energy will always be transferred from the hotter to the cooler object. The objects will exchange thermal energy, until thermal equilibrium is reached, until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
Answer:
As a child, Esperanza wants only to escape Mango Street. Her dreams of self-definition don't include the fact that she has any responsibility to her family or to the people around her, and she wishes to leave them all behind.

Answer:
-2.79 x 10²J
Explanation:
using the pressure volume work formula which states that
work = -PΔV
= -(1.0 atm) (2.7-0.0)L = -2.7L . atm
Convert litre.atmosphere to Joules.
1 L . atm = 101.325 joules
-2.75 L .atm = -2.75 x 101.325 = -278.64375 =
Work = -2.79 x 10²J
Answer:
t=444.4s
Explanation:
m=1.5*10^7 kg
F=7.5*10^5 N
v=80km/h*(1h/3600s)*(1000m/1km)=22.22m/s
<u>Second Newton's Law:</u>
F=ma
a=F/m=7.5*10^5/(1.5*10^7)=0.05m/s^2
<u>Kinematics equation:</u>
vf=vo+at=at
vo: initial velocity equal zero
t=vf/a=22.22/0.05=444.4s
