Answer:

You have a 2.0 L balloon filled with air at a temperature of 273 K.

240 K

323 K

655 K

900 K

Answer 2

• V1=2L
• V2=2.4L
• T1=273K
• T2=?

Apply Charles law

$\\ \rm\Rrightarrow V_1T_2=V_2T_1$

$\\ \rm\Rrightarrow 2T_2=2.4(273)$

$\\ \rm\Rrightarrow 2T_2=655.2$

$\\ \rm\Rrightarrow T_2=\dfrac{655.2}{2}$

$\\ \rm\Rrightarrow T_2=327.6K$
