Answer 1

1-d

2-a,c

3.

V₁/2=V₂

T₂=1,5T₁

p₁V₁/T₁=p₂V₂/T₂<=>p₁V₁/T₁=p₂*V₁/2/1,5T₁<=>p₁=p₂/2/1,5=p₂/3

p₁=p₂/3

3-d

4.

p₂=4p₁

ΔT=T₂-T₁=4=>T₂=4+T₁

p₁/T₁=p₂/V₂<=>p₁/T1=4p₁/(4+T₁)<=>4+T₁=4T₁<=>3T₁=4=>T₁=4/3=1,33=1,(3) K

T₁=1,(3) K

5.

T₁=253°C=526 K

p₂=p₁/2

p₁/T₁=p₂/T₂<=>p₁/526=p₁/2/T₂<=>2T₂=526=>T₂=526/2=263 K

T₂=263 K

6.

V₁=400 cm³=4*10⁻⁴ m³

V₂=424 cm³=4,24*10⁻⁴ m³

T₁=27°C=300 K

V₁/T₁=V₂/T₂=>T₂=T₁V₂/V₁=300*4,24*10⁻⁴/4*10⁻⁴=1275/4=318,75 K

La 1 nu stiu sigur daca e corect!
