Bài 1.

$\dfrac{p_1}{T_1}=\dfrac{p_2}{T_2}$

Vì p tỉ lệ thuận T nên:

$\dfrac{p_2}{p_1}=\dfrac{T_2}{T_1}$

$=>\dfrac{p_2}{p_1}=\dfrac{323+273}{25+273}=2 lần$

Bài 2.

$\dfrac{p_1}{T_1}=\dfrac{p_2}{T_2}$

$<=>\dfrac{p_1}{T_1}=\dfrac{2p_1}{T_1+313}$

$<=>\dfrac{1}{T_1}=\dfrac{2}{T_1+313}$

$=>T_1=313°K$

Bài 3.

$\dfrac{v_1}{T_1}=\dfrac{v_2}{T_2}$

$<=>\dfrac{v_1}{T_1}=\dfrac{\frac{20}{100}v_1+v_1}{T_1+6}$

$<=>\dfrac{v_1}{T_1}=\dfrac{1,2v_1}{T_1+6}$

$<=>\dfrac{1}{T_1}=\dfrac{1,2}{T_1+6}$

$=>T_1=30°K$

Bài 4.

$\dfrac{p_1v_1}{T_1}=\dfrac{p_2v_2}{T_2}$

$<=>\dfrac{p_1v_1}{T_1}=\dfrac{3p_1.\frac{1}{2}v_1}{T_1+97}$

$<=>\dfrac{1}{T_1}=\dfrac{3.\frac{1}{2}}{T_1+97}$

$=>T_1=194°K$
