4)Температура жидкости с ростом давления температура кипения увеличивается, а с уменьшением давления температура кипения уменьшается.
5)Q=qm
Q=46*10^6*0,2=9,2*10^6=9200 кДж
ответ :Q=9200 кДж
6)R=p*L/S
R=0,028*0,7/0,75=0,026 Ом
U=I*R=5*0,026=0,13 В
ответ :U=0,13 В
7)F=k*q1*q2/r^2
r=корень(k*q1*q2/F)
r=корень(9*10^9*5*10^-9*6*10^-9/12*10^-5)=0,04 м
ответ :r=0,04 м=4 см
8)n(кпд) =A/Q*100%
n=P*t/c*p*V(t2-t1) *100%
t=n*c*p*V(t2-t1) /P*100%
t=0,8*4200*1000*0,003(100-20)/600=1344 c =22,4 мин
ответ :t=22,4 мин
