Câu 3.
\(T_1=0^oC=273K\)
\(T_2=30^oC=30+273=303K\)
Qúa trình đẳng tích:
\(\dfrac{p_1}{T_1}=\dfrac{p_2}{T_2}\Rightarrow\dfrac{700}{273}=\dfrac{p_2}{303}\)
\(\Rightarrow p_2=776,92mmHg\)
Câu 4.
\(T_1=33^oC=33+273=306K\)
\(T_2=37^oC=37+273=310K\)
Qúa trình đẳng tích:
\(\dfrac{p_1}{T_1}=\dfrac{p_2}{T_2}\Rightarrow\dfrac{3\cdot10^5}{306}=\dfrac{p_2}{310}\)
\(\Rightarrow p_2=303921Pa\)
